[7] A negative screening test obviates the need for the cumbersome OGTT, the gold standard for GDM diagnosis, which is costly and is associated with multiple sampling, nausea and vomiting.
In univariate regression analysis (Table 2) between CC-resistant and CC-sensitive PCOS women, BMI, waist circumference, Ferriman-Gallwey score, oral glucose tolerance test (OGTT)- fasting/1 hr/ 2 hr values, HOMA-IR, LDL, HDL, triglyceride, cholesterol, androstenedione, AMH, LH-FSH ratio, ovarian volume, and antral follicle count were found to be statistically significant.
Louis, MO), dissolved in 150 mL of water for the OGTT. Blood samples were drawn at baseline and 120 minutes through an antecubital venipuncture into Vacutainer test tubes with ethylenediaminetetraacetic acid.
All 200 patients were subjected to comparative testing through a non-fasting 75 g oral glucose (DIPSI) and fasting 100 g OGTT interpreted by CCC at less than 20 weeks POG and again between 24-28 weeks POG, with a temporal separation of [less than or equal to]4 days between the non-fasting OGTT with the DIPSI criteria and fasting OGTT with CCC.
Serum glucose and insulin responses to OGTT were similar between groups pre-intervention.
Prediabetes involves a long asymptomatic period of impaired glucose metabolism that can be diagnosed by measurement of FPG, 2hr OGTT value and/ or HbA1c.
The American Diabetes Association (ADA) recommendation glycemic thresholds with 75gm OGTT are also similar to the IADPSG.5 The WHO criteria (75gm OGTT) glycemic thresholds for diagnosis of GDM are the same as for a people with impaired glucose tolerance (IGT) and DM outside pregnancy.6
"1h-PG is a useful predictor of retinopathy risk, has a predictive value similar to that of 2h-PG, and may be considered as an alternative glucose time point during an OGTT," the authors write.
If a predetermined threshold is met or exceeded, the second step is to administer a 100-g glucose load, 2-h OGTT (the diagnostic test).
A 50 g glucose challenge test (50 g GCT) is done, followed by a 100 g oral glucose tolerance test (100 g OGTT) in case of a positive screen (>140mg/dL).
