Easy to use With mixed reviews on how easy or difficult the blood typing kits are to use, I was a bit skeptical. I was also concerned I wouldn’t be able to interpret the results. For best and easiest use (and when I use the remaining kits for my adult kids), read the instructions and understand them before doing anything.
