tvåtimmarsglukos
tvåtimmarsglukos refers to the blood glucose level measured two hours after starting a meal. This measurement is a common component of an oral glucose tolerance test (OGTT). The OGTT is a diagnostic procedure used to evaluate how the body metabolizes glucose. During the test, a person drinks a liquid containing a specific amount of glucose, and their blood glucose levels are measured at intervals, typically including a fasting sample, one hour after ingestion, and two hours after ingestion. The two-hour postprandial (after meal) glucose level is particularly important for diagnosing impaired glucose tolerance and diabetes mellitus. Elevated two-hour glucose levels can indicate that the body is not effectively clearing glucose from the bloodstream, either due to insufficient insulin production or impaired insulin sensitivity. Generally, a two-hour glucose level below 7.8 mmol/L (140 mg/dL) is considered normal. Levels between 7.8 and 11.1 mmol/L (140 and 200 mg/dL) suggest impaired glucose tolerance, and levels of 11.1 mmol/L (200 mg/dL) or higher are indicative of diabetes. This measurement helps healthcare professionals assess an individual's risk of developing or diagnose existing metabolic disorders.
