The diagnostic threshold with the appropriate test and condition b. prediabetes—fasting, ≥100 mg/dl blood glucose . Therefore , b.prediabetes—fasting, ≥100 mg/dl blood glucose is correct .
The diagnostic criteria for prediabetes and diabetes are essential for identifying individuals at risk and managing their conditions effectively.
Let's break down the given options:
a. Prediabetes—OGTT, ≥200 mg/dl blood glucose:
This statement is not accurate.
The Oral Glucose Tolerance Test (OGTT) is commonly used to diagnose diabetes, but the threshold for prediabetes is typically a fasting blood glucose level of 100-125 mg/dl, not the mentioned ≥200 mg/dl.
b. Prediabetes—fasting, ≥100 mg/dl blood glucose:
This is the correct match. Prediabetes is often diagnosed with a fasting blood glucose level between 100-125 mg/dl.
Fasting blood glucose levels below 100 mg/dl are considered normal.
c. Diabetes—OGTT, ≥180 mg/dl blood glucose:
This statement is partially correct. The OGTT can be used to diagnose diabetes, but the threshold is usually a blood glucose level of ≥200 mg/dl, not ≥180 mg/dl.
d. Diabetes—fasting, ≥140 mg/dl blood glucose:
This statement is incorrect. The fasting blood glucose threshold for diagnosing diabetes is typically ≥126 mg/dl, not ≥140 mg/dl.
Option b is the correct match for prediabetes diagnosis using fasting blood glucose levels, while option c is partially correct for diabetes diagnosis using the OGTT, but the threshold should be ≥200 mg/dl, not ≥180 mg/dl.
