Which test would you expect to provide information on glucose metabolism?

The oral glucose tolerance test (OGTT) is specifically designed to assess the body’s ability to metabolize glucose. During this test, a patient ingests a standardized glucose solution, and blood samples are taken at intervals to measure how effectively glucose is cleared from the bloodstream. The results provide critical information regarding insulin response and overall glucose metabolism, helping to diagnose conditions such as prediabetes or diabetes.

In contrast, the other tests listed serve different diagnostic purposes. Thyroid-stimulating hormone (TSH) testing is used to evaluate thyroid function. C-reactive protein (CRP) testing is a marker for inflammation and does not provide insights into glucose metabolism. Lastly, low-density lipoprotein (LDL) testing is focused on measuring cholesterol levels and assessing heart disease risk, rather than evaluating how the body metabolizes glucose.
