Very easy-to-use at-home kit that provides lots of important lab results just from finger-prick blood. I wanted a reading of liver- and general metabolic health between annual physicals and labs. Was impressed with my first-time use of this kit and how quickly results were reported and in a very easy-to-interpret form. The only issue I had is that instructions call for "4 drops of blood" to fill the required area on the card until blood seeps to a guide line. It took several more large drops (will count next time). Not a big deal. I'll use this again.
