Glucose Tolerance Test

Is a test that evaluates how fast the body metabolizes glucose. It helps monitor blood sugar levels in diabetic individuals.

The Glucose Tolerance Test (GTT) helps diagnose diabetes and evaluates how effectively your body processes glucose. It involves tracking blood sugar levels at various intervals after consuming a glucose-rich drink. The GTT generally includes these steps:

  1. Fasting Blood Sugar
    Measures blood sugar levels following an overnight fast.
    Establishes a baseline to assess your body’s glucose response.

  2. Glucose Drink
    You will consume a liquid containing a specific glucose amount (typically 75 grams).
    The drink must be finished within a designated time (usually within 5 minutes).

  3. Blood Sugar Monitoring
    Blood samples are collected periodically (every 30 minutes to 2 hours) after drinking glucose.
    Monitors how efficiently your body metabolizes glucose over time.

  4. Oral Glucose Tolerance Test (OGTT)
    In some cases, an extended version called the Oral Glucose Tolerance Test (OGTT) is performed.
    The OGTT includes additional blood sugar checks over a period of up to 3 hours.

  5. Results Interpretation
    Blood sugar levels recorded during the GTT or OGTT are compared to standard values.
    Results help determine normal glucose tolerance, impaired tolerance, or diabetes risk.

Abnormal readings may indicate prediabetes (impaired glucose tolerance) or diabetes, depending on test results. The Glucose Tolerance Test is a crucial diagnostic tool for detecting diabetes and assessing glucose metabolism. It helps identify early glucose intolerance, allowing timely intervention to manage or prevent diabetes. The test is conducted under medical supervision, and adherence to fasting and preparation guidelines is essential for accurate results.

  • What type of Test do your Laboratory offer?
    We offer tests such as Complete blood tests, urine tests, Bilirubin Blood Tests, Lipid profile Tests, Glucose Blood Tests, Electrolyte Analysis and diagnostic screenings for various diseases and conditions.
  • How long will it take to receive the Blood Results?
    The turnaround time for test results can vary depending on the type of test performed. Routine tests often have a quicker turnaround time, with results typically available within 24 to 48 hours. Complex tests or those requiring additional analysis may take longer, and we strive to provide accurate results as efficiently as possible.
  • Can I take an Appointment to visit, or should I visit directly ?
    Appointments are recommended to ensure minimal waiting time and to allow us to allocate the necessary resources for your test. However, we also accept walk-ins and strive to accommodate everyone efficiently. Scheduling an appointment is the best way to guarantee a convenient and streamlined experience.
  • Are there any special things to consider before coming for any tests ?
    Some tests may require specific preparations, such as fasting for a certain duration before blood work or avoiding certain medications prior to the test. Our team will provide you with detailed instructions and any necessary preparations when you schedule your test to ensure accurate results.
