Ketostix Urine Reagent Strips

Ketostix are dip-and-read urine test strips used to detect and estimate ketone levels, giving you a fast at-home reading without a meter or blood sample. They matter most to two groups: people managing diabetes who need to catch rising ketones before they become dangerous, and those following ketogenic or low-carb diets who want confirmation their bodies are producing ketones. The test itself is simple — dip a strip in a fresh urine sample, wait the specified number of seconds, then compare the reaction pad against the color chart on the bottle, from negative through trace, small, moderate, and large.

This collection carries genuine Ascensia (Bayer) Ketostix. The Ascensia Ketostix Urine Reagent Strips, 100 per Bottle (2881) is the value size for anyone testing regularly, while the Ketostix Urine Reagent Strip (2880) offers the same trusted ketone measurement in a smaller quantity. Each strip reads only ketones (acetoacetic acid), so results are quick and easy to interpret against a single color scale.

A few practical points buyers ask about: strips work best with a fresh sample and accurate timing, so read at exactly the interval printed on the label. Keep the bottle tightly capped and stored away from heat and humidity — moisture degrades the reagent pad — and note the discard date once opened. For people with diabetes, moderate to large ketone readings, especially alongside high blood sugar, warrant a call to your healthcare provider. Ketostix estimate ketones but don't measure glucose; pair them with your regular monitoring routine.
