Which urine dipstick test detects acetone in the urine?

The detection of acetone in urine is specifically associated with the presence of ketones. When the body metabolizes fat for energy, especially during prolonged periods of fasting, low-carbohydrate diets, or uncontrolled diabetes, ketones are produced as a byproduct. Acetone is one of the three main types of ketones found in the body, the other two being acetoacetic acid and beta-hydroxybutyric acid.

A urine dipstick test designed to measure ketones will indicate the presence of these compounds, including acetone. The test works by utilizing a chemical reaction on the dipstick that changes color when ketones are present in the urine, providing a visual indication of ketosis.

The other options do not pertain to the detection of acetone specifically. The protein test detects the presence of protein in urine, which can indicate kidney issues, while the pH test measures the acidity or alkalinity of the urine. The bilirubin test screens for bilirubin, a substance produced from the breakdown of red blood cells, which can signify liver function issues or bile duct obstructions. Therefore, the choice that accurately identifies acetone in urine is the ketones test.
