Ketone testing strips check for the presence in urine of one type of ketone, called acetoacetic acid. Read the directions that come with your strips for proper use. Youâll either run the strip through a stream of urine or collect urine in a clean container and dip the strip into it.
The urinary ketone test uses sodium nitroferricyanide (sodium nitroprusside). Acetoacetic acid induces a color change (to lavender) by reducing the iron in the nitroferricyanide to its ferrous state. Acetylcysteine can also reduce the iron moiety, causing a false positive test for urinary ketones. Irrigating solutions containing acetylcysteine should be added to the list of medications and substances that can result in such false positive tests.
