A Glucose Tolerance Test (GTT) is a diagnostic tool used to assess how well your body processes glucose (sugar). It’s commonly used to diagnose type 2 diabetes, gestational diabetes, and insulin resistance. This test measures your blood sugar levels before and after consuming a glucose-rich drink.
The Glucose Tolerance Test (GTT) evaluates how efficiently your body regulates glucose levels over time. It involves:
Initial fasting blood sample to measure baseline glucose
Ingestion of a glucose solution
Follow-up blood samples taken at intervals (usually 1, 2, or 3 hours)
This test provides detailed information about your body's ability to manage sugar and can identify abnormalities even before symptoms develop.
Before the Test:
You may need to fast for 8–12 hours
You’ll be advised to avoid smoking and certain medications beforehand
During the Test:
A fasting blood sample is taken
You’ll drink a sweet glucose solution
Additional blood samples will be taken over the next few hours
You’ll need to stay at the clinic during the test period
After the Test:
Your results will be reviewed by a healthcare professional
Further testing or treatment may be recommended based on findings
GTT services are typically conducted by:
Phlebotomists or nurses in clinical or hospital settings
GP surgeries, antenatal clinics, or specialist diabetes centres
Pathology labs and diagnostic clinics
All providers available through My Health Assistant are qualified and experienced in performing GTTs safely and accurately.
You may be referred for a GTT if you:

Have risk factors such as obesity, PCOS, or a family history of diabetes
Are being monitored for insulin resistance or prediabetes
Depending on your health status, the following GTT types may be offered:
Standard Oral Glucose Tolerance Test (OGTT) – for diagnosing type 2 diabetes
Pregnancy GTT – typically done between 24–28 weeks gestation
Extended GTT – includes more blood draws over several hours for in-depth analysis
Your healthcare provider will determine the appropriate version for your needs.
The GTT is a very safe and routine procedure. Minor risks may include:
Temporary dizziness or nausea after drinking the glucose solution
Bruising or slight discomfort from multiple blood draws
Mild hypoglycemia in some individuals during the test
All risks are minimal and easily managed by medical professionals.
