Glucose-Insulin Three-Specimen Testing
Glucose-insulin three-specimen testing measures blood sugar and insulin together at three points. The first draw is taken fasting. The next two follow a glucose drink, at one hour and at two hours. Reading insulin beside sugar shows how hard the pancreas is working.
A fasting sugar alone can look normal for years while insulin climbs to hold it there. Pairing the two catches the earlier pattern. That matters because insulin resistance disturbs ovulation in many women with PCOS, now named PMOS (polyendocrine metabolic ovarian syndrome).
The signal is measurable. One study compared 50 women with PCOS and 50 women without it, matched for body size. Fasting insulin and fasting blood sugar both ran higher in the PCOS group.1
