1
Indicates whether the Na+ was below lower limit of reference range for patient age at time of specimen collection.
2
Indicates whether the Cl- or HCO3− was above upper limit of reference for patient age at time of specimen collection.
3
Note that some patients had multiple specimens with different categories so that sum of results exceeds number of unique patients.
