Which statement about the random blood glucose test is true?

• A. It is a blood test taken randomly with a glucose level of 200 mg/dL or higher indicating diabetes
• B. It must be performed after overnight fasting
• C. It measures cholesterol
• D. It requires 24-hour urine sample

Answer: (A)

The random blood glucose test is a casual measurement of blood sugar taken without regard to meals. A reading of 200 mg/dL or higher, in the presence of classic symptoms of hyperglycemia (such as increased thirst, urination, and unintended weight loss) or a hyperglycemic crisis, supports a diagnosis of diabetes. This is why that statement is true: it emphasizes the non-fasting nature of the test and the diagnostic threshold when symptoms are present. The other statements aren’t correct because fasting isn’t required for this test, it doesn’t measure cholesterol, and it doesn’t rely on a 24-hour urine sample.
