How a Glucose Tolerance Test (GTT) report is read
- The oral glucose tolerance test should be performed after an overnight fast of 8 to 14 hours using a 75 g oral glucose load.
- Diagnostic criteria differ for gestational diabetes.
- Acute illness, vomiting during the test, or recent carbohydrate restriction may affect the validity of the results.
What commonly goes wrong with a Glucose Tolerance Test (GTT)
The practical errors that actually cause repeat samples and misread results, mostly at collection and at the point the result is read.
- The patient must eat a normal unrestricted carbohydrate diet for three days before the test, roughly 150 g of carbohydrate a day. Patients who cut rice and roti to "prepare" for the test push their values up, not down.
- The clock starts at the first sip of the glucose load, not when the glass is empty. The load should be finished within about five minutes and each tube labelled with its time slot at the moment of draw, since swapped 1 hour and 2 hour tubes are a common error that leaves no trace on the report.
- The patient stays seated and at rest for the whole duration, with no smoking and no walking outside. If the patient vomits the load, the test is abandoned and repeated on another day, not reported with whatever samples were collected.
- Antenatal protocols differ, and the fasting 75 g WHO test and the non fasting 75 g DIPSI test are not the same procedure. Applying one protocol's cut-offs to the other's sampling is a frequent mix-up, so the request form and the report should both state which protocol was performed.
