Evaluation of the analytical and clinical accuracy of four blood glucose meters in pregnant women with hyperglycaemia.

ABSTRACT:

Aims

Physiological changes during pregnancy can infuence the performance of blood glucose meters. This study aimed to evaluate the analytical and clinical accuracy of glucose meters in pregnant women with hyperglycaemia.

Materials and methods

Glucose was measured by four commonly used meters among consecutive women with diabetes in pregnancy. Capillary and venous samples were collected concurrently and compared with i-STAT (amperometry) and laboratory (hexokinase) glucose as reference methods. Bland-Altman plot, International Organization for Standardization criteria, surveillance error grid (SEG) and haematocrit influence were assessed.

Results

In total, 824 paired samples from 103 women were analysed (GDM 57%, mean i-STAT capillary glucose 6.7 ± 2.3 mmol/L [121 ± 41
