Screening test for gestational diabetes.
The 1 Hour After 50gm Glucose Test (Glucose Challenge Test – GCT) measures how well the body processes sugar. The patient drinks a solution containing 50 grams of glucose, and blood is collected after one hour to check glucose levels. It helps identify women at risk of gestational diabetes during pregnancy. Note : Arogga will provide Glucose (Charge applicable)

How our test process works!
Overview
1 Hour After 50 gm Glucose Test (also called Glucose Challenge Test – GCT) measures how efficiently the body processes sugar after consuming a 50-gram glucose solution. It is primarily used to screen for gestational diabetes mellitus (GDM) during pregnancy.
Risk Assessment
-
Detect early glucose intolerance or insulin resistance during pregnancy.
-
Helps identify women at risk of gestational diabetes, which can lead to complications like:
-
Fetal macrosomia (large baby)
-
Preeclampsia
-
Cesarean delivery
-
Neonatal hypoglycemia
-
Normal Range
| Result (mg/dL) | Interpretation |
|---|---|
| < 140 mg/dL | Normal (no GDM) |
| 140–189 mg/dL | Borderline – needs confirmatory 3-hour 100 gm OGTT |
| ≥ 190 mg/dL | Suggestive of gestational diabetes |
Interpretation
-
If glucose < 140 mg/dL → Normal glucose handling.
-
If ≥ 140 mg/dL, a confirmatory oral glucose tolerance test (OGTT) with 100 gm glucose is recommended.
-
High values indicate reduced glucose tolerance, suggesting possible gestational diabetes mellitus (GDM).
Sample Type
-
Venous blood sample collected 1 hour after consuming 50 gm of oral glucose.
-
Fasting is not required for this test.
