A 45year old patient is having FBS 111mg/dl, PPBS 181mg/dl, HbA1C 6.1%. The diagnosis is
**Core Concept**
The patient's laboratory results indicate impaired glucose regulation, with a diagnosis that falls between normal glucose metabolism and overt diabetes mellitus.
**Why the Correct Answer is Right**
The patient's Fasting Blood Sugar (FBS) is 111mg/dl, which is higher than the normal range (<100mg/dl), but not high enough to diagnose diabetes mellitus. The Postprandial Blood Sugar (PPBS) is 181mg/dl, which is also elevated, but not diagnostic of diabetes. The Hemoglobin A1C (HbA1C) is 6.1%, which is below the threshold for diagnosing diabetes (≥6.5%). However, the patient's HbA1C is higher than normal (<5.7%), indicating impaired glucose regulation. This is consistent with a diagnosis of **Impaired Glucose Tolerance (IGT)**.
