What is a GTT (75gm glucose) Test in Visit Clinic?

The GTT (75gm glucose) measures how your body handles a fixed glucose load. It tracks blood sugar levels over time after you drink a 75 gram glucose solution. This shows how well insulin and your pancreas are working to clear sugar from the blood. Doctors use it to find diabetes, prediabetes, and gestational diabetes. It also helps when symptoms are unclear or when screening is needed because of risk factors. Results guide treatment, lifestyle changes, and follow-up testing. The test gives more detail than a single fasting sugar reading. It can reveal problems with glucose control that might otherwise be missed.

Do not eat or drink anything except water for 8-12 hours before the test

Why Take a GTT (75gm glucose) Test in Visit Clinic?

GTT (75gm glucose) is part of diabetes screening and gestational diabetes evaluation. Doctors may order it if you have symptoms like excessive thirst, frequent urination, unexplained tiredness, or if routine blood sugar tests are borderline. It helps diagnose diabetes, prediabetes, and pregnancy-related glucose intolerance. Abnormal results can come from poor diet, obesity, insulin resistance, certain medicines, or pancreatic disease. A family history of diabetes often makes this test important.

What is the GTT 75 gm glucose test in Visit Clinic?

The GTT 75‑gram glucose test (oral glucose tolerance test) evaluates how your body processes a 75 g oral glucose load to detect diabetes or gestational diabetes. After overnight fasting a baseline blood sample is taken, you drink the glucose solution, and blood glucose is measured at set intervals (commonly 1 and 2 hours). Results are compared to standard thresholds to diagnose impaired tolerance or diabetes.

What is the cost of 75gm glucose test in pregnancy in Visit Clinic?

The 75 g oral glucose tolerance test cost varies widely. On public systems (e.g., NHS) it’s free for pregnant women. In private settings prices typically run about £30–£80 (UK), ₹200–₹800 (India) or roughly $20–$200 (US), depending on lab and insurance. Check your local clinic or lab for exact fees and whether it’s covered by your antenatal care.

What happens if GTT is positive in Visit Clinic?

A positive glucose tolerance test means your blood sugar rose above the threshold, indicating gestational diabetes or impaired glucose regulation. Care typically includes dietary and exercise changes, regular glucose monitoring, and sometimes medication (metformin or insulin). You’ll receive closer pregnancy and fetal monitoring to reduce risks (large baby, pre‑eclampsia, delivery complications). Follow-up glucose testing is recommended after delivery.

What is a normal GTT level for a pregnancy test in Visit Clinic?

A normal glucose tolerance test (75 g OGTT) in pregnancy is: fasting less than 92 mg/dL (5.1 mmol/L), 1‑hour less than 180 mg/dL (10.0 mmol/L), and 2‑hour less than 153 mg/dL (8.5 mmol/L). A 50 g screening test typically uses a 1‑hour cutoff around 130–140 mg/dL for further testing, but diagnosis relies on the 75 g OGTT thresholds above.

How does gestational diabetes affect the baby in Visit Clinic?

Gestational diabetes can cause fetal overgrowth (macrosomia), increasing risk of difficult delivery, shoulder injury and cesarean section. Babies may develop low blood sugar (neonatal hypoglycemia), breathing problems, jaundice and preterm birth. Uncontrolled maternal glucose also raises risks of stillbirth and long-term child obesity and type 2 diabetes. Good pregnancy monitoring and treatment reduce these risks.

Can I eat before the 75g glucose test in Visit Clinic?

No — you should fast before a 75 g oral glucose tolerance test. Typically you fast 8–14 hours and may drink only water; avoid food, sugary drinks, gum, and smoking. Take only medications your clinician permits and avoid heavy exercise beforehand. Follow your provider’s instructions and call them if you’re unsure about eating or taking medicines that could affect results.
