Oral Glucose Tolerance Test (O-GTT)

This test evaluates how the body handles glucose over a defined period after a glucose challenge. It provides information about glucose regulation and may help identify abnormal blood sugar responses. Healthcare professionals may use it when assessing possible diabetes, impaired glucose tolerance, or pregnancy-associated glucose intolerance when clinically appropriate. Results are interpreted according to the sequence and timing of glucose measurements together with symptoms, medical history, and other relevant clinical findings.
