GK Dual Blood Ketone Test Strips (x25)


Our GK Dual ketone teststrips are admired for their accuracy. Used daily by thousands of ketonians, and health professionals.

The GK Dual® Blood Ketone Test Strips are thin strips with a chemical reagent system which work with the On Call® GK Dual and the Go-Keto Blood Glucose & Ketone Meter to measure the blood β-Ketone (beta-hydroxybutyrate) concentration in whole blood. Blood is applied to the end tip of the test strip, and then automatically absorbed into the reaction cell where the reaction takes place. A transient electrical current is formed during the reaction and the blood β-Ketone concentration is calculated based on the electrical current detected by the meter, then the result is shown on the meter display. The meters are calibrated to display plasma equivalent results.
