The GCT (Glucose Challenge Test) measures blood sugar after consuming 75 grams of glucose, commonly used to screen for diabetes or gestational diabetes.
The GCT - Blood Sugar (Post Glucose 75 Grams) test, also known as the Glucose Challenge Test (GCT) or Oral Glucose Tolerance Test (OGTT), measures how efficiently your body processes glucose. This test is particularly important for diagnosing diabetes and gestational diabetes (a type of diabetes that develops during pregnancy). In this test, blood sugar levels are measured after the consumption of a 75-gram glucose drink, providing insights into how well the body manages glucose after a defined sugar intake.
The GCT - Blood Sugar (Post Glucose 75 Grams) test assesses the body's ability to process glucose after ingesting a standard 75-gram glucose solution. When glucose is consumed, the pancreas should release insulin, which helps cells absorb glucose, bringing blood sugar levels back to a normal range. This test reveals if glucose levels remain elevated after consumption, which could indicate an inability to produce or effectively use insulin.
This test is helpful for:
Diagnosing diabetes or prediabetes: Elevated glucose levels after consumption suggest diabetes or prediabetes.
Screening for gestational diabetes in pregnancy: Commonly conducted between 24-28 weeks of pregnancy, as high blood sugar can affect both mother and baby.
Monitoring glucose tolerance over time: Useful for individuals with risk factors for diabetes or insulin resistance.
This test is recommended for Individuals at risk for diabetes: Those with a family history, high body mass index (BMI), or lifestyle factors that increase the likelihood of diabetes. Pregnant women: Especially those between 24-28 weeks of pregnancy or those with risk factors for gestational diabetes. Individuals with symptoms of diabetes: Common symptoms include increased thirst, frequent urination, fatigue, and unexplained weight loss. People with pre-existing conditions: Conditions such as PCOS (polycystic ovary syndrome), hypertension, or heart disease can elevate the risk of diabetes.

1. GCT - BLOOD SUGAR ( POST GLUCOSE 75 GRAMS After 2 hrs. )
2. Urine Sugar ( POST GLUCOSE 75 GRAMS After 2 hrs. )
Depending on whether a baseline (fasting) glucose reading is also needed, fasting may be required. Your healthcare provider will guide you on any preparation.
A high glucose level indicates the body may not be processing glucose effectively, suggesting potential diabetes or prediabetes. In pregnant women, high levels may indicate gestational diabetes.
While primarily used for diagnosing diabetes, this test also helps assess how well glucose is managed in the body, which is valuable for conditions like insulin resistance or gestational diabetes.
The entire process takes about two hours from the time you drink the glucose solution.
