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

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!

The kids and I did this while studying a science unit on blood. They were very impressed! The instructions were well written and the process was flawless. Now, thankfully, we each have a good idea of our blood type which we didn't know peviously.

Worked well as advertised to get my kids blood types. I knew one kids already, so these confirmed accurate.

I was nervous to use after reading the reviews but it actually worked really well and so easy on the first try!

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.

Came with very clear instructions and tools, you don't need to be a rocket scientist for this.

Quick results and easy to understand directions.

Product gave great directions and it was easy to follow! Would recommend to a friend!
