Is the comparative laboratory method the same as the CardioChek method?
• Are you using whole blood? (Ketone is the only test strip that uses whole blood, serum, or plasma. All other test strips require fingerstick whole blood or venous whole blood collected in either EDTA or heparin tubes.) • Is an adequate sample size used? Too much or too little blood may give an inaccurate result. Check your package insert for the correct sample size. (Most single tests require 15 µL; multiple test panels require 25 µL – 40 µL.) A capillary blood collector, capillary tube, or pipet must be used to ensure accurate dosing.
