I purchased the CardioChek 3 in 1. Chloresterol home test kit. I used all the test included in the kit. 3-over all Chloresterol, 3- HDL and 3-Triglyceride. Just for accuracy. I had a Chloresterol test at my doctor and all nine of these test were accurate. With only one test off by two points. I know the results could be off based on each and every machine due to it being calibrated from factory prior to shipping. But I must say my machine was on point. Very pleased...
