Which test can be used as a confirmatory test for ketones in urine and other body fluids?

The Acetest tablets test is a confirmatory test for ketones in urine and other body fluids because it specifically reacts with acetoacetate, one of the primary ketone bodies produced during ketosis. When the Acetest tablet is introduced to a sample, it undergoes a color change that indicates the presence of ketones, providing a reliable and straightforward method for confirmation.

In contrast, ketone strip tests, while useful for initial screening, may not be as specific or sensitive for all ketone types compared to the Acetest. Benedict's test is primarily used for detecting reducing sugars and does not evaluate ketones at all. The Jaffe reaction is associated with the measurement of creatinine levels and is not applicable for ketone detection. Therefore, the Acetest serves as the most appropriate confirmatory method for identifying ketones in biological fluids.
