Sokerirasitustesti

Sokerirasitustesti, also known as an oral glucose tolerance test (OGTT), is a medical diagnostic procedure used to assess how the body metabolizes glucose. It is commonly employed to diagnose conditions such as gestational diabetes mellitus during pregnancy and type 2 diabetes mellitus in the general population. The test involves several steps, beginning with a fasting blood sample taken after the patient has abstained from food and drink for at least eight hours.

Following the initial blood draw, the patient consumes a standardized sugary drink, typically containing 75 grams of glucose dissolved in water. After drinking the solution, the patient remains at rest, usually for two hours. During this waiting period, the body processes the ingested glucose, and its levels in the bloodstream fluctuate.

At the end of the two-hour period, a second blood sample is drawn. In some cases, additional blood samples may be taken at one-hour intervals between the fasting and two-hour marks to obtain a more detailed profile of glucose metabolism. The laboratory then analyzes the blood samples to measure glucose concentrations.

The results are interpreted by comparing the measured glucose levels to established diagnostic criteria. Elevated glucose levels at specific time points can indicate impaired glucose tolerance or diabetes. For gestational diabetes, specific criteria are used during pregnancy, and the test is usually performed between the 24th and 28th week of gestation. The sokerirasitustesti is a valuable tool for early detection and management of these metabolic disorders.
