Diagnosis of diabetes and blood glucose monitoring guidelines

Diagnosis of diabetes	- glycaemia ≥2 g/L, associated with clinical signs
	- fasting blood glucose ≥1.26 g/L on two occasions
	- blood glucose ≥2 g/L 2 hours after OGTT
HbA1c >6%	- should trigger more frequent blood glucose monitoring,
	- given that the anemia frequently observed in transplant patients
	can alter HbA1c
In patients with weight loss, thirst and polyuria (particularly at night),	- capillary blood glucose monitoring must be performed
	- before a meal and two hours thereafter
	- with a ketone research.
If 2 capillary blood glucose values >1.50 g/L,	- monitoring must be continued
	- regardless of whether or not the patient is symptomatic.
When corticosteroid therapy is initiated	- check postprandial blood glucose ++
	- may be elevated even when pre-prandial glycaemia is
	normal regardless of the clinical signs.
During a steroid therapy step-down phase	- frequent monitoring recommended, to avoid hypoglycemia.
During the period of insulin adjustment	- capillary glycaemia should be monitored
	- 6 x/day (before each main meal and 2 hours thereafter).
If not possible to obtain regular self-monitoring	- try to obtain 6 or 7 measurements over 2 or 3 days
	- or refer the patient for a 3- to 7-days continuous
	ambulatory glucose monitoring
When nocturnal enteral nutrition is initiated,	- perform 1 or 2 night-time and a morning capillary blood glucose to adjust the evening dose of insulin.

Once the treatment parameters have stabilized, monitoring can be relaxed, with measurement of pre-prandial and postprandial glycaemia (at 2 hours) after one of the day’s meals.
