During a health screening, a random blood glucose is 200 mg/dL. What is the next appropriate step?

• A. Call the health care provider to have the value rechecked as soon as possible.
• B. Seek treatment for diabetes mellitus.
• C. Begin blood glucose monitoring three times a day.
• D. Ask the pharmacist about starting insulin therapy.

Answer: (A)

A single random glucose of 200 mg/dL is abnormal, but it does not by itself diagnose diabetes. The best next step is to have the value rechecked by a healthcare provider as soon as possible. This confirms whether the high result is persistent or a one-time spike from factors like recent meals, stress, illness, or lab error. After rechecking, the clinician will guide further testing (such as fasting glucose, HbA1c, or an oral glucose tolerance test) to establish whether diabetes is present. Starting treatment or insulin based on one reading is not appropriate, especially in a screening setting without symptoms. If symptoms of hyperglycemia are present, that would push toward a more urgent evaluation, but still typically requires confirmatory testing.
