The dipstick protein detection can detect as little as 5-20 mg of protein per deciliter. Which option accurately states this range?

The dipstick protein detection can detect as little as 5-20 mg of protein per deciliter. Which option accurately states this range?

• A. 1-2 mg/dL
• B. 5-20 mg/dL
• C. 50-100 mg/dL
• D. 200-500 mg/dL

Answer: (B)

Protein on a dipstick is detected by a color-changing pad that responds to albumin in urine, and its sensitivity is about 5 to 20 mg per deciliter. This means it can pick up the presence of protein starting around 5 mg/dL and provides detectable changes up to roughly 20 mg/dL in the lower range. Therefore, the statement that matches this detection capability is 5–20 mg/dL. Values well below that (like 1–2 mg/dL) may be undetectable, while higher ranges (50–100 mg/dL, 200–500 mg/dL) reflect higher concentrations but are not describing the stated detection limit.
