What Random Blood Glucose value indicates a hyperglycemic state requiring prophylaxis?

• A. > 200 mg/dL
• B. > 180 mg/dL
• C. > 150 mg/dL
• D. > 250 mg/dL

Answer: (A)

The key concept is recognizing the diagnostic threshold for hyperglycemia using a random blood glucose test. A random glucose value above 200 mg/dL, especially if the patient has typical symptoms of hyperglycemia, indicates diabetes and prompts medical evaluation and management to prevent complications. In practice, this level signals that prophylactic planning—such as postponing elective dental procedures until glucose is controlled and obtaining medical clearance—may be necessary to reduce risks like infection or poor healing. Values below this threshold do not by themselves diagnose hyperglycemia, while a higher value confirms hyperglycemia but the critical cutoff for concern is the 200 mg/dL mark.
