Implication

Prospective study demonstrates high diagnostic accuracy of point-of-care capillary glucose testing in pregnant women, suggesting a viable alternative to standard venous sampling.

Key Points

To assess the clinical accuracy of capillary point-of-care glucose testing compared with standard venous blood sampling during an oral glucose tolerance test for diagnosing gestational diabetes mellitus.
Conducted a prospective study of 353 pregnant women at risk for gestational diabetes at an antenatal clinic in Heerlen, The Netherlands, between August and November 2021.
Collected paired capillary and venous blood samples at fasting, 1 hour, and 2 hours following a glucose load, analyzing them using the Accu-Chek Inform II and Cobas 8000 systems, respectively.
Assessed diagnostic sensitivity, specificity, and predictive values using IADPSG criteria, evaluating measurement agreement through Bland-Altman and Passing-Bablok analyses.
Point-of-care testing demonstrated an overall diagnostic sensitivity of 92.3% and a negative predictive value of 98.8% for gestational diabetes mellitus.
Peak diagnostic performance occurred at 2 hours post-load, showing a sensitivity of 96.3% and a specificity of 91.9%.
Area under the ROC curve was 0.94 at fasting, 0.97 at 1 hour, and 0.98 at 2 hours, with Bland-Altman mean differences from venous measurements ranging between 0.07 mmol/L and 0.81 mmol/L.
