What is the glucose dipstick range in a urinalysis?

• A. 0 to >2000 mg/dL
• B. 0 to 500 mg/dL
• C. 0 to 1000 mg/dL
• D. 0 to 200 mg/dL

Answer: (A)

The glucose dipstick range in a urinalysis is significant for diagnosing and monitoring conditions like diabetes mellitus, as it reveals the presence and concentration of glucose in the urine. The range provided by a dipstick test typically extends from 0 to >2000 mg/dL. This broad range allows for the detection of various levels of glycosuria, from normal (0) to very high levels (>2000 mg/dL). In clinical practice, a dipstick that can show values greater than 2000 mg/dL is useful because it indicates not only the presence of glucose but also a potential acute hyperglycemic event, which is essential for patient management. Glucose levels above the renal threshold (approximately 180 mg/dL) will be excreted in the urine, and a percentage of individuals with uncontrolled diabetes may present extremely high glucose levels in their urine, justifying the upper limit of over 2000 mg/dL. Therefore, the selection that states a range of 0 to >2000 mg/dL accurately portrays the testing capability of glucose dipsticks in a urinalysis context.
