Average Reviews:
(More customer reviews)The rest of my family members were able to find out their blood type when they first donated blood, but since I don't weigh enough to donate, I figured that I would only find out my own type if I ever needed a transfusion for some reason. Maybe it's because I'm a science nerd, but I really couldn't help wondering which antigens my red blood cells are carrying, so I was very excited to come across this inexpensive kit. Having read reviews that mentioned ambiguous results, I was extra meticulous in following the instructions and fortunately came out with a very clear result. It's not a difficult process, but it helps to pre-read the instructions and organize your materials before starting. The instructions also include an internet address were you can view a video demonstration of the procedure if it's unclear to you. Basically, you add a drop or two of blood to 4 different substances on the card and check to see if your blood reacts or not. In addition to improper technique, I'm guessing vague results could possibly indicate a rare blood type? Otherwise, your blood either reacts or it doesn't. A non-reaction just looks like smeared blood. However, if your blood does react, you will see it change from the smeared appearance to a speckled appearance as the blood cells clump together. You can have larger or smaller clumps depending on how strong the reaction is, but basically: No reaction = no distinct clumps or specks; Reaction = clumps/specks that have separated out. One of the substances on the card is a control and shouldn't cause any reaction unless there was a manufacturing defect, so as long as the blood just looks smeared around on that part of the card, you can use it to compare. You do have to realize that the results depicted in the instructions are just illustrations; they're not actual photographs so you can't expect your results to look exactly like them. Also, it might be easier to tell once the blood has dried. I've uploaded a picture of what my results look like (after drying) as an example.
In any case, the kit is not that expensive, so it's worth a try if you really want to know your blood type and have no cost-free alternative means of finding out (e.g. blood bank).
