Recommendations on Measurement Units – Why and How

Young Bae Lee Hansen 1,
PMCID: PMC6803776  PMID: 31695584

Abstract

Globally, laboratories are producing, communicating, and exchanging millions of laboratory examination values to multiple parties every day. For most values, ‘measurement units’ are required to make the numerical values comparable and meaningful. However, a non-systematic use of ‘measurement units’ can create errors in communication between health care providers and become a risk to patient safety. Therefore, the Committee of Nomenclature for Properties and Units (C-NPU) recommends using an unambiguous terminology of ‘measurement units’, for daily patient care and scientific publications. In this work, C-NPU summarizes the recommendations on ‘measurement units’, explaining the reasons and the principles of the ‘measurement units’ used in laboratory medicine.

Key words: weights and measures, metric system, international system of units, health information interoperability, health communication, medical informatics

INTRODUCTION

‘Measurement unit’ (unit) is a well-understood and necessary concept in laboratory medicine. Without units, most quantitative laboratory examination values will not make sense and are not comparable. Dybkær and Jørgensen wrote in 1967: “To state that the mass concentration of haemoglobin in a blood sample is 25 is essentially meaningless. If the unit g/L is assumed, the patient is considered anaemic. If the unit g/dL is assumed, the patient is considered to be polycytaemic” (1).

With the introduction of the International System of Units (SI units) (2) in the 1960’s, the worldwide scientific laboratory societies have accepted and, to a large extent, implemented the SI units for presentation of laboratory reports in health care and research. However, as indicated by the recent campaign of the European Federation of Clinical Chemistry and laboratory Medicine (EFLM), there is nevertheless a further need of standardisation or harmonisation on a national, regional, and international level (3). The campaign recommended implementation of the “principles on units”, proposed by Dybkær and Jørgensen in 1967 (1). These principles are more restricted than the original SI-system to ensure unambiguity in reporting, presenting, and exchanging quantity values in health care. Each laboratory may choose any relevant units for reporting laboratory examination values, but when multiple parties are involved in exchanging laboratory reports, the choice should be limited to the “principles on units”. Arguably, the principles will reduce the risk of post-analytical errors, e.g. misunderstanding and misinterpretation of laboratory reports and errors in communication between different health care personnel and organisations.

The “principles on units” in laboratory medicine, as initially proposed by Dybkær and Jørgensen, have been implemented in the Nomenclature for Properties and Unit (NPU) terminology (4, 5).

In this letter, we summarise the IFCC’s and IUPAC’s Recommendations and Technical Reports on relevant principles and rules on units in laboratory medicine, and the reasons behind these principles.

KIND-OF-QUANTITY, QUANTITY, AND MEASUREMENT UNIT

In order to understand the concept ‘measurement unit’, it is necessary to see its close relation to the other essential metrological concepts ‘kind-of-quantity’ and ‘quantity’. ‘Mass’, ‘substance concentration’, and ‘volume fraction’ are examples of ‘kinds-of-quantity’ that place system and any relevant component in a mathematical relation. E.g., ‘substance concentration’ is defined as “amount-of-substance of component B divided by volume of system 1” or:

graphic file with name ejifcc-30-250-e001.jpg

On a more tangible level, the system and component can be specified further including a magnitude, e.g.:

graphic file with name ejifcc-30-250-e002.jpg

The latter example is a ‘quantity’, having the formal and metrological definition “property of phenomenon, body, or substance, where the property has a magnitude that can be expressed as a number and a reference” (6). The differences between both concepts are shown in Table 1.

Abstract kind-of-quantity substance concentration Inline graphic
Measurable quantity substance concentration of sodium ion in Mr. Smith’s plasma is 143 mmol/L at 2:30 p.m. on 2nd May 2018. Inline graphic

In the example for ‘quantity’, ‘plasma’ is the ‘system’, ‘sodium ion’ is the ‘component’ and ‘substance concentration’ is the ‘kind-of-quantity’. Also, there is a magnitude according to the definition of ‘quantity’, as compared with the example for ‘kind-of-quantity’ that does not have a magnitude.

In laboratory medicine, eight ‘base kinds-of-quantity’ exist as listed in Table 2 with their corresponding ‘base units’ and ‘quantity dimensions’ (5). The ‘base kinds-of-quantity (e.g. ‘amount-of-substance’) can be combined in various ways, forming ‘derived kinds-of-quantity’, e.g. ‘substance concentration’.

A list of base kinds-of-quantity and their corresponding base units and dimensions from IFCC’s and IUPAC’s ‘Silver Book’ (5). Note: ‘Number of entities’ is not an SI base kind-of-quantity but is used as a base kind-of-quantity in laboratory medicine.

To ‘substance concentration’, the corresponding compound unit can be, e.g., mmol/L. To a (base or derived) kind-of-quantity, several corresponding units are possible. Examples of corresponding units to ‘substance concentration’ are ‘mol/L’, ‘mmol/L’, ‘μmol/L’, ‘nmol/L’, etc. A comprehensive description of ‘kinds-of-quantity’ and ‘measurement units’ can be found in IFCC’s and IUPAC’s ‘Silver Book’ (5)–together with ‘kind-of-nominal-property (related to ‘nominal properties’ which have no magnitude).

Reporting solely the numerical value and unit may not be sufficient information on the examination because the possible corresponding ‘kind-of-quantity’ to e.g., ‘g/L’, could be ‘mass concentration’ or mass density’. Moreover, in order for the clinicians to assess the values of laboratory examinations, especially laboratory examination reports from other laboratories, it is essential to provide information about the generic nature of the laboratory examinations. Thus, C-NPU recommends to report, systematically, the system, component, kind-of-quantity (or kind-of-nominal property) and, when relevant, the unit for a given laboratory examination.

GENERAL RULES FOR SI UNITS AND NON-SI UNITS

It is recommended to use units with unambiguous definitions, accepted by international scientific communities. Such units can be SI units and non-SI units.

1. Base SI units

The definitions, symbols, and magnitudes of SI units are traced to accepted international references (Table 2) (2).

Examples

“The metre is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second” (2).

“The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom” (2).

Note: From the year 2019, all seven SI base units will be defined in terms of constants. The practical use of the seven SI base units will not change (7).

2. Unit of a given magnitude should have only one expression

For a unit with a given magnitude, there are several possible expressions, e.g.:

graphic file with name ejifcc-30-250-e003.jpg

Such variety may cause errors in communication between health personnel and organisations.

To ensure unambiguity in reporting values, only one expression for a unit of a given magnitude should be used.

3. Multiples and submultiples of units

To present numerical values in the interval of 0.1-999(8) and to make values with very large or very small numerical values readable, the units can be combined with SI prefixes, expressed as either SI prefix symbols or SI prefix factors (numerical values) (Table 3).

Table 3.

SI prefixes: factors, terms, and symbols

Factor Term Symbol Factor Term Symbol
101 deca da 10–1 deci d
102 hecto h 10–2 centi c
103 kilo k 10–3 milli m
106 mega M 10–6 micro μ
109 giga G 10–9 nano n
1012 tera T 10–12 pico p
1015 peta P 10–15 femto f
1018 exa E 10–18 atto a
1021 zetta Z 10–21 zepto z
1024 yotta Y 10–24 yocto y

SI prefix table from the SI Brochure: The International System of Units (SI) [8th edition, 2006; updated in 2014] (BIPM) (2).

To avoid errors in communication with potential patient mistreatments as consequences, multiple combinations of SI prefixes should not be allowed. Thus, the following rules apply:

  • One SI prefix per unit

  • The SI prefix belongs to the numerator only

Only one SI prefix per unit should be used. Combinations of SI prefixes are to be avoided (Table 4).

Table 4.

Examples of one SI prefix per unit

The mass of haemoglobin per erythrocyte in Mr. Smith’s blood is 31 pg.
Millimole per litre mmol/L μmol/mL The substance concentration of sodium in Mr. Smith’s plasma is 134 mmol/L.

An SI prefix in the denominator should be avoided in a compound unit (Table 5).

Table 5.

Examples of SI prefix in the numerator

Micromole per litre μmol/L nmol/mL The substance concentration of bilirubins in Mr. Smith’s plasma is 8 μmol/L.
Millimole per kilogram mmol/kg μmol/g The mass of calprotectin in Mr. Smith’s faeces is 8 mmol/kg.

An exception is that ‘kilogram’ (and not ‘gram’) is the base SI unit for mass and therefore can be expressed in the denominator as ‘kg’.

4. Units for kinds-of-quantity of Dimension One (dimensionless)

Kind-of-quantity of Dimension One (dimensionless) is a “quantity for which all the exponents of the factors corresponding to the base quantities in its quantity dimension are zero” (6). The ‘base kind-of-quantity’, ‘number of entities’ and kinds-of-quantity with the same ‘kind-of-quantity’ (dimension) in the numerator and denominator, e.g. ‘mass fraction’

graphic file with name ejifcc-30-250-e004.jpg

or ‘substance ratio’

graphic file with name ejifcc-30-250-e005.jpg

have the dimension one, according to the rules of algebra. The corresponding coherent units for these kinds-of-quantity are numerical values, e.g., ‘one’ or SI prefix factors. The specified ‘kind-of-quantity’ along with the corresponding unit in the laboratory report provide the full nature of the quantity measured.

For the ‘kinds-of-quantity’ of Dimension One with the corresponding unit ‘one’, the unit symbol is often omitted for the values of these types (Table 6).

Table 6.

Examples of the unit ‘one’ for kinds-of-quantity of Dimension One

Unit Unit symbol Examples of deprecated symbols Examination example with correct unit
One 1 - The number of cavities in Mr. Smith’s teeth is 2.
kg/kg
mg/mg
The mass fraction of free prostata specific antigen of total prostata specific antigen in Mr. Smith’s plasma is 0.14.
mol/mol

The substance fraction of methaemoglobin of haemoglobin in Mr. Smith’s blood is 0.03.
L/L

The volume fraction of erythrocytes of Mr. Smith’s blood is 0.42.
s/s
min/min
The time of tissue factor-induced coagulation in Mr. Smith’s plasma divided by the time of tissue factor-induced coagulation in the certified reference material, IRP 67/40, is 1.0 (INR).

To express very small or very large values, the units should be expressed as SI prefixes, according to the rules of multiples and submultiples of units. To avoid confusion with unit symbols, SI prefix factors should be used, not the SI prefix symbols (Table 7).

Table 7.

Examples of SI prefix factors as units for kinds-of-quantity of Dimension One

Unit Unit symbol Examples of deprecated symbols Examination example with correct unit
Ten to the power of 6 per litre 106/L M/L*
M×1/L

Ten to the power of -3 per litre 10-3/L m/L**
m×1/L
The number concentration of RNA from Human immunodeficiency virus 1 in Mr. Smith’s plasma is 0 × 10-3/L.

* ‘M’ is the SI prefix symbols for ‘mega’

** ‘m’ is the SI prefix symbols for ‘milli’.

Consequently, redundant units are avoided because the same unit ‘one’ or SI prefix factors can represent units of various dimensionless kind-of-quantities and different expressions of a unit of a given magnitude (Table 6 and Table 8).

Table 8.

Examples of SI prefix factor representing various units

(The albumin value is adjusted to the amount-of-substance of creatininium in urine).
Inline graphic The number fraction of reticulocytes of erythrocytes in Mr. Smith’s blood is 10 × 10-3.

Another issue to address is conversion of unit from ‘one’ to ‘%’ for a kind-of-quantity of dimension ‘one’, e.g. erythrocyte volume fraction (EVF). EVF can be expressed with ‘one’ or ‘%’ as units, whereas ‘one’ is usually omitted. Without the indication of unit, it may be tempted to convert from ‘one’ to ‘%’. Values of erythrocyte volume fraction (EVF) will be reported either as “0.42” or “42”. Despite the small and simple conversion from ‘one’ to ‘%’ the laboratory report with both type of results will cause confusion, if not interpreted by a conscious human mind.

5. Units for quantities of the same sort of system, sort of component(s), and kind-of-quantity should differ at least by a factor of one thousand

A laboratory examination of a quantity with a given sort of system, sort of component(s), and kind-of-quantity can be reported with different corresponding units, according to the choice of the local laboratories. To reduce misinterpretations that may occur when exchanging laboratory results between hospitals or when health personnel change hospitals, it is recommended that the laboratories use units that differ by at least a prefix factor of one thousand (103) for the same type of examination performed in 2 or more laboratories.

E.g. Laboratory A measures the substance concentration of epinephrine in plasma with the unit, ‘μmol/L’. Laboratory B performs the same type of measurement but present the value with a unit that differs at least by a prefix factor of one thousand. In this case Laboratory B uses the unit, ‘nmol/L’.

Example

NPU14042 Plasma—Epinephrine; substance concentration = ? μmol/L

NPU04625 Plasma—Epinephrine; substance concentration = ? nmol/L

This recommendation is to prevent overlapping intervals of value sets for a specific laboratory examination. Often, value sets vary for the same laboratory examination using different units, but these variations may overlap when the units differ by a factor of 10 or 100, e.g. ‘cm’ and ‘mm’, ‘%’ and ‘‰’, or ‘dL’ and ‘L’. The overlaps can cause misinterpretation, when the clinicians incorrectly assume use of the unit they are familiar with for a result from another laboratory (see example below). Thus, the use of SI prefix factors: centi (c), deci (d), deca (da) and hecto (h) are discouraged, except when the units are lifted to a power (see section 7.3).

Example

Laboratories A and B (in Hospitals A and B, respectively) measure number fraction of the reticulocytes among erythrocytes in Mr. Smith’s blood with the use of two different units. The units differ by a factor of 10 (see below laboratory reports from laboratories A and B).

The patient is regularly admitted to Hospital B, but due to practical difficulties, a blood sample from the patient is analysed by Laboratory A in the patient’s hometown. The health care personnel at hospital B may not react adequately on the value ‘1’ from laboratory A on 24th January, because the value lies in a familiar value set interval and could mistakenly be interpreted to be within Laboratory B’s reference interval (Table 9).

Table 9.

Erythrocytes (Blood)—Reticulocytes; number fraction** 1 0.8 - 0.5–2.2 ×10-2

* Examination result from Lab A.

** Examination result from Lab B.

6. Non-SI units

Besides the non-SI units accepted for use together with the SI system, e.g., litre, (Table 10), there are two important internationally used expressions for non-SI units in laboratory medicine: ‘WHO International Unit’ (IU) and ‘(procedure defined unit)’ (p.d.u.).

An extract of a list of accepted non-SI units from BIPM (2).

6.1 WHO International Unit (IU)

The term ‘WHO International Unit’ (IU) does not indicate one unit but comprises a heterogeneous group of units, each defined by internationally certified reference material (CRM), (e.g. a WHO International Standard). Thus, the given CRM defines the material and magnitude of the unit. ‘IU’ should not be confused with the symbol for enzyme unit ‘U’ that is defined as ‘μmol per minute’ (5).

A current CRM may not be permanent for a specific measurand, and the magnitude of the unit may be redefined by a new CRM batch (see examples below). To distinguish between different IUs, the given CRM should be stated in the examination report.

In the NPU terminology, the specific CRM is a part of the laboratory examination code (in the examples below ‘IS 09/172’ and ‘IS 84/665’ are specific CRMs).

Examples

NPU58076 Plasma —Coagulation factor IX; arbitrary substance concentration (enzymatic; IS 09/172; procedure) = ? IU/L

NPU01636 Plasma —Coagulation factor IX; arbitrary substance concentration (enzymatic; IS 84/665; procedure) = ? IU/L

Note: The modifier ‘arbitrary’ is ambiguous. Sometimes it is used for ‘random’. This is not the case here. An ‘arbitrary substance concentration’ is a substance concentration decided and defined by an ‘arbiter’. In this case ‘WHO’ is the ‘arbiter’.

The use of SI prefix factors is allowed in descriptions of very small or very large values, because the international CRM has a well-defined magnitude. However, SI prefixes are not recommended in combination with IU expressions due to confusion with the symbol for the ‘enzyme unit’, U (Table 11). E.g. ‘kU/L’ can be mistaken for ‘kIU/L’, and ‘mU/L’ for ‘mIU/L’.

Table 11.

Examples of use of SI prefix for ‘International Unit’ and ‘enzyme unit’

Unit Unit symbol Examples of deprecated symbols Examination example with correct unit
103 International Unit per litre ×103 IU/L kIU/L The arbitrary substance concentration of Birch -IgE in Mr. Smith’s plasma is 10 × 103/L.
10-3 International Unit per litre ×10-3 IU/L mIU/L The arbitrary number concentration of RNA from Hepatitis C virus in Mr. Smith’s plasma is 200 × 10-3 IU/L.
10-3 enzyme unit per litre mU/L ×10-3 U/L The catalytic-activity concentration of guanosine deaminase in Mr. Smith’s plasma is 250 mU/L.
103 enzyme unit per litre kU/L’ ×103 U/L The catalytic-activity concentration of pancreatic amylase in Mr. Smith’s duodenal fluid is 40 × 103 U/L.

6.2 Procedure defined unit (p.d.u.)

If the unit is defined by a measurement procedure that is not traceable to an international unit or an international CRM, the laboratory must describe and term the unit used. Such units are frequently termed ‘arbitrary unit’, ‘arbitrary unit/L’, ‘ELISA unit’, etc. — without any indication of either dimension or magnitude.

The NPU terminology uses the term ‘(procedure defined unit)’, symbolized ‘(p.d.u.)’, to indicate that the NPU terminology does not specify the unit for the kind-of-quantity in question. Although it may appear to be a well-defined unit, the concept contains a heterogeneous group of arbitrary and proprietary units.

It reflects the disagreement of the unit magnitudes between different assays and no common CRM.

The actual magnitude of the unit depends on the analytical measurement procedure, and it is the responsibility of the laboratory to communicate the required information for clinical evaluation of the laboratory reports.

Thus, the ‘(procedure defined unit)’ is a simple placeholder for the units that one or more laboratories have termed and described.

Local symbols for these non-SI units should not look like SI-units, such as ‘mg/L’, to prevent misunderstanding of laboratory values.

Example

NPU29718 Plasma—3-hydroxy-3-methylglutaryl-coenzyme A reductase antibody (IgG); arbitrary substance concentration (procedure) = ? (procedure defined unit)

In this case, the local term for the ‘(procedure defined unit)’ could be, e.g., ‘arbitrary unit/L’.

Combinations of the term ‘(p.d.u.)’ with SI prefixes and/or SI- or non-SI units are meaningless, as they may represent units of any magnitude and dimension (Table 12).

Table 12.

Examples of use of procedure defined unit

Unit Unit symbol Examples of deprecated symbols Examination example
Procedure defined unit (p.d.u.) (p.d.u.)/kg The arbitrary substance content of haemoglobin in Mr. Smith’s faeces is 20 ELISA unit/kg.
m(p.d.u.)
10-3× (p.d.u.)

Comparisons on a national or regional level require harmonisation and pre-coordination for the laboratory examinations using ‘(p.d.u.)’ as unit.

7. Exceptions

Units that violate some of the above rules may exceptionally be accepted as follows.

7.1 International recommendation on specific units

Well-defined and unambiguous units that violate the above stated rules may be acceptable for use if an international recommendation has been established.

Example

‘Millimole per mole’ (‘mmol/mol’) was recommended by IFCC for the laboratory examination of ‘HbA1C’ (9).

7.2 Per cent

Many kinds-of-quantity defined as fractions are by convention and very long tradition expressed with the unit ‘per cent’ (‘%’ or ‘10-2’), however, it is recommended to use caution when using this unit due to the high risk of errors in communication between health personnel, as explained in section 5. Therefore, if there is a strong international need of using ‘%’ as unit for a specific laboratory examination, an international recommendation needs to be established for that specific laboratory examination.

Example

‘Per cent’ was recommended by IFCC for the laboratory examination ‘carbohydrate-deficient transferrin (CDT)’ (10).

NPU57406 Transferrin (Plasma)— Disialotransferrin; substance fraction (IFCC 2016) = ? %

Consequently, for the NPU terminology, NPU codes for that laboratory examination, using ‘one’ or ‘10-3’ as units, cannot be established due to risk of misinterpretation of exchanged laboratory results. This will ensure that only ‘%’ will be reported in any laboratory.

7.3 Units lifted to a power

For units lifted to a power, e.g. ‘cm2’ and ‘m3’, the SI prefixes with a factor less than 1000 are acceptable for a laboratory examination with the same system, component, and kind-of-quantity. E.g. ‘mm2’, ‘cm2’, ‘dm2’ and ‘m2’ are acceptable, because they ensure steps of at least a factor of 100 between the numerical values.

The intervals of the value sets for these units are not overlapping, and there is no increased risk of misinterpretation in exchanging laboratory reports.

Examples

Patient—Body Surface; area = 1.8 m2

Patient—Body Surface; area = 180 dm2

Patient—Body Surface; area = 18 000 cm2

Patient—Body Surface; area = 1 800 000 mm2

Note: The two bottom entries should for readability purposes not be established (see Section 3: Multiples and submultiples of units).

CONCLUSION

Globally, millions of laboratory examinations are performed, communicated, exchanged, and presented every day. Moreover, as patients (and health care personnel) are traveling between hospitals and other health care organisations, patient health data are communicated between these organisations as well.

The risk of post-analytical misinterpretations — especially of the exchanged laboratory data — is, thus, high and may induce errors in patient care. To reduce risk and support optimal interoperability, the reviewed principles on measurement units are recommended for use by all parties in health care IT systems and organisations, and in scientific publications in the field of health care.

To illustrate our recommendations regarding measurement units, we provide a list of two hundred frequent laboratory examinations with units as used in Danish, Dutch, Norwegian, and Swedish laboratories. See Supplement to ‘measurement units’ (in Table 13, after the References section).
