Glukoosirasitusta

Glukoosirasitusta, also known as a glucose tolerance test, is a medical diagnostic procedure used to assess how the body processes glucose. It is commonly employed to diagnose prediabetes and diabetes mellitus. The test typically involves two main steps. First, a fasting blood glucose level is measured after a period of not eating or drinking for at least eight hours. Following this initial measurement, the individual consumes a standardized sugary drink containing a specific amount of glucose. Their blood glucose levels are then measured at regular intervals, usually one and two hours after consuming the drink.

The results of the glukoosirasitusta indicate how efficiently the body absorbs and utilizes glucose from the bloodstream. Elevated glucose levels after the oral glucose load can suggest impaired glucose metabolism. A fasting glucose level below 5.6 mmol/L and a 2-hour post-load level below 7.8 mmol/L are considered normal. Levels between 7.8 and 11.1 mmol/L at the 2-hour mark indicate impaired glucose tolerance, a precursor to type 2 diabetes. Levels of 11.1 mmol/L or higher at the 2-hour mark, along with a fasting glucose of 7.0 mmol/L or higher, are indicative of diabetes. This test is a valuable tool for early detection and management of glucose metabolism disorders.
