What is the Glucose Tolerance Test (GTT) test?

An oral glucose tolerance test measures how well your body handles a known amount of sugar. Rather than taking one reading, it looks at your blood glucose before you drink a sugary liquid and again afterwards, which shows how quickly your body clears sugar from the blood. NIDDK explains that this helps detect type 2 diabetes, prediabetes and gestational diabetes. At Marham Lab an OGTT costs PKR 700 and your report is ready the same day.

OGTT and GTT: The Same Test

OGTT stands for oral glucose tolerance test. GTT is the shorter form used on most Pakistani lab forms and prescriptions. Sugar tolerance test is the everyday name people use. All three mean the same procedure. One name that is genuinely different is the glucose challenge test, or GCT, sometimes called the glucose screening test. That one is a single sample taken an hour after a sweet drink, with no fasting required. NIDDK describes it as a screening step in pregnancy, and notes that if the result comes back at roughly 135 to 140 mg/dL or higher, you would then return for a full fasting OGTT.

What the Test Measures

TestWhat it showsFasting needed
OGTTHow your body clears a measured sugar load over 2 hoursYes, at least 8 hours
Fasting plasma glucoseOne glucose reading after an overnight fastYes, at least 8 hours
HbA1cAverage blood glucose across roughly 3 monthsNo
Glucose challenge testA single reading 1 hour after a sweet drink, used to screen in pregnancyNo

NIDDK is candid that the OGTT is more expensive and harder to administer than the simpler tests. Its advantage is sensitivity. It catches problems with glucose handling that a single fasting reading can miss.

Normal Range

These are the NIDDK thresholds for a result taken 2 hours after the glucose drink, for people who are not pregnant.

Result 2 hours after glucoseWhat it indicates
139 mg/dL or belowNormal
140 to 199 mg/dLPrediabetes
200 mg/dL or aboveDiabetes

If you are pregnant, different cut offs apply and your doctor will explain which ones your clinic uses. NIDDK also notes that a doctor will usually confirm a diabetes diagnosis with a second test rather than acting on one result.

What High Values Mean

ResultWhat it can meanWhat usually happens next
Prediabetes rangeYour body is handling sugar less efficiently than it should. This raises the chance of developing type 2 diabetes, but NIDDK is clear that type 2 diabetes can be prevented from hereYearly retesting, and changes to diet and activity. This is the stage where action works best
Diabetes rangeBlood glucose is above the diabetes thresholdA confirming test, then a treatment plan with your doctor
High two or more times during a pregnancy OGTTYou may have gestational diabetesCare through the pregnancy, and a further test for type 2 diabetes usually within 12 weeks after delivery

A single number does not diagnose anything on its own. Take the report to a doctor.

Who Should Get Tested and When

NIDDK recommends testing for type 2 diabetes if you carry certain risk factors, including being aged 35 or older, being overweight with at least one other risk factor, or having had gestational diabetes previously. South Asian populations are among those listed at higher risk.

The pregnancy schedule is more specific, and worth knowing because it is easy to miss.

  • Anyone planning a pregnancy should be tested for type 2 diabetes beforehand, especially with risk factors
  • If already pregnant, test for type 2 diabetes at the first prenatal appointment or within the first 15 weeks
  • All pregnant women without a previous diabetes diagnosis should be tested for gestational diabetes between 24 and 28 weeks
  • After a gestational diabetes pregnancy, test again for type 2 diabetes, usually within 12 weeks of delivery
  • If results are normal, retest every 3 years. If you have prediabetes, retest every year

Anyone with symptoms of diabetes should be tested regardless of risk factors. NIDDK also warns against trying to diagnose yourself with an over the counter glucose meter, which cannot diagnose diabetes.

How to Prepare

Fast for at least 8 hours before the test. Fasting means nothing to eat or drink except sips of water. Book a morning slot, because the test itself takes several hours and you will be fasting until the first sample is drawn. Tell your doctor about any medicine you take, and mention if you are unwell on the day, since illness can affect glucose readings. Do not skip the fast and turn up anyway. An OGTT taken without proper fasting produces a result nobody can interpret, and the whole appointment is wasted.

What Happens During the Test

This is the part people are least prepared for, so plan your day around it. A phlebotomist takes a first blood sample while you are still fasting. You then drink a measured sugary liquid. A second sample is taken 2 hours later. If you are pregnant, NIDDK notes your blood is drawn every hour for 2 to 3 hours instead, so there are more samples. You need to stay for the whole period, and you should not eat, drink anything else or walk around a great deal between samples, because activity changes how your body handles the sugar. Bring something to occupy yourself. Because this test needs several samples across 2 to 3 hours, ask when booking whether home collection is practical for your slot or whether a collection point suits you better.

Conditions It Can Help Detect

The OGTT identifies type 2 diabetes, prediabetes and gestational diabetes. Prediabetes is the one worth pausing on, because NIDDK is explicit that developing type 2 diabetes can be prevented from that stage. Finding it is the point of testing before symptoms appear. The test cannot tell your doctor which type of diabetes you have. NIDDK notes that distinguishing type 1, type 2 and rarer monogenic forms needs other tests, such as autoantibody or genetic testing, and that the type matters because treatment differs.

Final Thoughts

The OGTT asks a question a single blood sugar reading cannot: not what your glucose is right now, but how well your body copes when challenged. That is why it catches prediabetes and gestational diabetes early. The two things to get right are the 8 hour fast and setting aside the full morning. Book it when your doctor asks for it, or when you are pregnant and reaching the 24 to 28 week window, and take the result to a doctor rather than reading the number alone.

Common questions

Plan for 2 to 3 hours at the collection point, which surprises most people. A first sample is taken while you are fasting, you drink the glucose liquid, and a second sample follows 2 hours later. If you are pregnant, NIDDK notes blood is drawn every hour for 2 to 3 hours, so there are more samples and the visit is longer. You need to remain there throughout and avoid eating, drinking or moving about much between samples.

Yes, fast for at least 8 hours. NIDDK defines fasting as nothing to eat or drink except sips of water, so plain water is allowed. Arriving without having fasted makes the result uninterpretable and the appointment has to be repeated, so book a morning slot and stop eating the night before.

NIDDK advises that all pregnant women without a previous diabetes diagnosis be tested for gestational diabetes between 24 and 28 weeks. You may be screened first with a glucose challenge test, which needs no fasting, and sent for a full fasting OGTT only if that result is around 135 to 140 mg/dL or higher. Pregnancy uses different cut offs from the standard ones, so ask your doctor what your clinic applies.

Sometimes, but not always, and pregnancy is the main exception. NIDDK notes the A1C test may not be accurate in the second or third trimester of pregnancy, or if you have certain kinds of anaemia or another blood problem, because haemoglobin variants can interfere with the measurement. An [HbA1c test](/labs/tests/hba1c-test-price) is far more convenient since it needs no fasting, but if you are pregnant or anaemic your doctor may specifically want the OGTT instead.
