Tests for gestational diabetes.
Doctor Slinkin will likely evaluate your risk factors for gestational diabetes early in your pregnancy:
If you’re at high risk of gestational diabetes — for example, if you were obese at the start of your pregnancy; you had gestational diabetes during a previous pregnancy; or you have a mother, father, sibling or child with diabetes — your doctor may test for diabetes at your first prenatal visit.
If you’re at average risk of gestational diabetes, you’ll likely have a screening test for gestational diabetes sometime during your second trimester — typically between 24 and 28 weeks of pregnancy.Your doctor may use the following screening tests:
Initial glucose challenge test. You’ll begin the glucose challenge test by drinking a syrupy glucose solution. One hour later, you’ll have a blood test to measure your blood sugar level. A FBS level below 140 mg/dL (7.8 mmol/L) is usually considered normal on a glucose challenge test, although this may vary at specific clinics or labs.
f your blood sugar level is higher than normal, it only means you have a higher risk of gestational diabetes. Denis recommends a re-examination to dtermine if you have gestational diabet.
Follow-up glucose tolerance testing. For the follow-up test, you’ll be asked to fast overnight and then have your fasting blood sugar level measured. Then you’ll drink another sweet solution — this one containing a higher concentration of glucose — and your blood sugar level will be checked every hour for a period of three hours.
If at least two of the blood sugar readings are higher than the normal values established for each of the three hours of the test, you’ll be diagnosed with gestational diabetes.
