The OGTT test with 75g of glucose (oral glucose tolerance test) is a specific laboratory analysis used to assess glucose tolerance in the body. This test includes consuming 75g of glucose orally and monitoring blood glucose levels at specific time intervals within 120-180 minutes. The analysis is extremely important for diagnosing diabetes and identifying potential glucose tolerance disorders, making it one of the more significant blood tests for diabetes.

Significance of this analysis

The 75 g glucose tolerance test is highly clinically important in diagnosing Diabetes mellitus and glucose tolerance disorders and assessing insulin resistance. The professional team at IntroLab, a private laboratory in Belgrade, will use this test to measure glucose and insulin levels simultaneously, providing important clinical information about the organism’s metabolic status.
