Glükoosikoormustesti

Glükoosikoormustesti, also known as an oral glucose tolerance test (OGTT), is a medical diagnostic procedure used to assess how the body metabolizes glucose. It is primarily used to diagnose diabetes mellitus, gestational diabetes, and impaired glucose tolerance. The test involves measuring blood glucose levels at specific intervals after a person consumes a standardized amount of glucose.

The procedure typically begins with a fasting blood sample being drawn. The individual then drinks a sweet liquid containing a measured amount of glucose. Following this, blood samples are taken at regular intervals, usually one hour and two hours later, though sometimes additional samples may be collected. These measurements indicate how efficiently the body absorbs and utilizes glucose from the bloodstream.

Elevated blood glucose levels at the standard time points can suggest impaired glucose tolerance or diabetes. Gestational diabetes, which occurs during pregnancy, is specifically diagnosed using a version of this test. The results are interpreted based on established diagnostic criteria set by medical organizations. It is a non-invasive and relatively straightforward test, though it requires the individual to fast beforehand and remain in a clinical setting for the duration of the testing period.
