Eldoncard Blood Typing Kit, 3 Test Pack, Know Your Blood Type, Accurate Instant Home Testing, Determine A, O, B, Rhs-D Negative & Positive Groups

These worked very well and were accurate. I purchased enough to do the whole family, followed the directions exactly, and they all functioned as they should. For some reason it is very difficult to get a doctors office to request a blood-typing unless there is a true medical need... much easier and cheaper to use these kits at home.

Easy home use blood type kit. I bought the three test kit so we tested two other family members with quick results. It’s been so long since I knew what my blood type is and this is a cost effective and quick way to find out without having to leave my home.

Works great! Hospital doesn't tell you what type of blood your baby has anymore( at least mine doesn't). So I got to fine out his blood type. Tested my husband and mine too. As we know ours and to to see is it is right. It was on both of ours. So I believe my son's is right as well.

Good product

Read all the instructions first. I’ll add to 2 tips below. Our 3 kits showed manufacture 2 months ago and expire in 2 years. The lancets required a surprising amount of pressure to activate, which was intimidating for the first person, then we all agreed the actual stick was more heard as a click than felt/hurt as pain. Regarding accuracy: Apparently accurate. We had 3 adults. One served as the control who had his official lab test result of B+ to compare against; another who had notes from discussing her lab test results of AB- with the doctor years ago and wanted confirmation that she noted correctly; and a third who thought she was O+ but did not remember how she got that impression. All 3 came out exactly as expected, no confusion, apparently accurate. First, as other reviewers said, the hardest part is transferring 4 good-sized blood drops from your finger to the right spots on the card. We found that position matters, and it helps to use gravity in your favor. When choosing where to poke your finger for the blood draw, hold your non-dominant hand with the palm facing you, and identify which side of the desired finger is down. That is the spot you should to use. It seems awkward to use the lancet there, but makes it much easier to gather the blood with less frustration or chance of contamination. Gravity will help form nice drops that your dominant hand can then gather onto to the sticks easily. We learned this the hard way, after one of us instinctively chose the top side of the finger because it was easier to prick, then the blood ran down the finger and smeared on the sticks, so we had to use first aid supplies like sanitary gauze pads and additional alcohol wipes to clean the smears off the finger and see the next drop forming. That was stressful and wasted time, plus gathered smaller blood samples for less clear results. Second, in the last steps of tipping the card around, ignore the specific angle for 10 seconds. It would let the samples run into and contaminate each other. Instead, gently tilt/rock the card around slowly, moving almost constantly in various directions to swirl all the samples but not let any of them run outside the boundaries of their own circles.

This kit might be quicker and easier than tracking down your blood type from your doctor’s office! The test was simple to administer and had a learning curve similar to an at-home COVID test—just follow the step-by-step instructions, and you’ll be fine. I used it on myself, an elementary-aged child, and a toddler. The finger prick was straightforward, even for someone with no medical background. It’s about the same experience as a finger stick at the doctor’s office—manageable for adults but understandably a little unpleasant for kids. The results were easy to read, with clear and definitive outcomes. If you need to determine your blood type at home, this is a convenient and reliable option. Highly recommend!

We did not know my kids' blood types for sure. Very easy instructions to follow and easy to read results.

I have to revise my review. I did the test twice with the first set I ordered and both results showed that my results were O Negative. I ordered a second set of tests so that my aunt and mother could test themselves to be sure of their B+ result. They haven't tested themselves yet. Since there was an extra kit and I'd already poked myself twice I decided to test myself a third time since this is a different batch. This time my result was O Positive. So I'm questioning the authenticity of these tests. Maybe one was a faulty batch? But if I'm O Negative and say I'm O Positive and am given + blood it will kill me if I'm actually -, so I'm thinking now I would rather go to someone official and get my blood tested, as this has given me two completely different results. Below is my original review: I had been told my blood type was O Positive my entire life only to learn recently that my mother apparently guessed my blood type, so I ordered the kit. I did one, and didn't have any clotting so that means it's O Negative. My aunt, who is my mom's twin sister, was with me and immediately was fascinated and she started wondering if her blood type was correct. So she took the second test, which came up to be B Positive, which she'd always assumed she was O Positive like my mom had. This made me a little wary of the results of the test, so I did mine a second time and got the same exact results, so I'm going to assume that it's accurate. I'm ordering a second set though to double check my aunt's, my mom's, and then my own once more just to make sure it's consistent. I do NOT like needles at all and it took me several minutes of panic to finally brave up and use the lancet. Then it didn't, and you have to really push hard to get it to go. Make sure the water dissolves the little circles on the pad as those are the antigens that'll clot the blood and show you your type and note you do NOT need a lot of water or blood to make it work. Quick, easy, and fascinating.
