Eldoncard INC Blood Type Test (Complete KIT) - Find Out if You are A, B, O, AB & RH- Results in Minutes - Air Sealed Envelope, Safety Lancet, Micropipette, Cleansing Swab - 1 Pack

It definitely worked, although I had the opposite issue as a lot of people, once I pricked my finger it wouldn’t stop gushing blood, so by the time I added the blood to each circle it was flowing down my hand and dripping to the floor and took around 20 minutes to fully stop bleeding even with pressure (I am NOT on blood thinners), so just be careful when getting the blood for the sample.

These are very easy to do. We followed the instructions to a t... it was very easy to follow and to get the results. All the negative reviews just seem like operator error. This product is cost effective to find out what your blood type is versus going in and having to fork out more time, effort and money and with them drawing more of your blood than necessary.

This was an amazing project I did with my kids. The directions are easy to follow and straight forward. You prick a finger like you would for a glucose reading. You dab the blood onto cards. Follow the directions and you should get accurate results. Both my kids used this and they found out that they are a+ which is correct because that is my blood type and my husband is 0, which they would automatically be a+. So, to me, it's accurate. I definitely recommend it

Very easy to perform test. The most difficult thing is to get the yellow cover off the lancet. Be sure to twist and pull. Because of strength, I had to use small plates on end and pull. Yes they were cleaned and dipped in alcohol just in case.

If you follow the instructions correctly these are easy to use and will you give you almost instant trustworthy results. I allowed a family member to administer the first two and the results were confusing and inconclusive. How do I know? I already knew my blood type before allowing him to help. So please only allow a responsible trustworthy adult to perform the test.

Easy, and it works really well. Just watch the video they have on their site (upc code is included), and only use one little drop of water per square out of the included bulb.Very happy to get clear results for the $10 this costs.

The test quickly gave me the results. I saw the test area reacting almost immediately. The tiny lancets were a little disappointing. It was difficult to get enough blood.

One star deducted for having the alcohol wipe be totally dry, making have to go get isopropyl alcohol to clean my finger when I was already nervous about the lancet! My test was still good (according to dates on the package) for another year-and-seven-months!***********************************************************************It was waiting in the kitchen for my blood…I kept finding other things to do.Anything to keep busy and stave off having to draw blood from my finger using the lancet in my brand-new blood group test kit that arrived in the mail today. It’s an EldonCard blood group test kit.ABO/Rh Blood Typing KitI wanted to know if I was A, B, AB, O and + or – just like they talk about on TV. Plus know what velcro tactical morale blood type patch to buy for my jacket.Blood isn’t this simple actually!Did you know there are thirty-six different blood type systems? The ABO and Rh Resus factor are just two systems that this card tests. Then there are the differences between Red Blood and just plasma, it seems simple, but it’s really dumbed-down by doctors (and movies and TV shows).Actually, the EldonCard only tests parts of the ABO and Rh systems: the Rh factor has 49 different “types” but we’re only checking for one: positive or negative (circle D). As far as the ABO part: blood type “A” has around 20 different subgroups, some of which are not interchangeable! There are over 300 different antigens that can be tested for in the different blood type systems.So what does this kit do?Basically, the A circle has anti-A chemicals on it, which clot up it touches A blood. The B circle has b antigens that clot up if it touches B blood. When you look at the clotted blood: it looks like polka dots which is why you need to NOT give certain people certain blood types during a transfusion: all their blood with clot up and kill them.Huh? What does this kit show?There are four circles: A, B, D and Control:If A clots: you’re type A.If B clots: you’re type B.If A & B both clot: you’re type AB.If neither A or B clot: you’re type O.If Circle D clots you’re positive.If Circle D does NOT clot you’re negative.Circle Control: if this clots you messed up the test/it was defective from the factory. Buy a new Eldoncard!How do you use the kit?1. You put a drop of water on each of the circles.2. Wipe your finger with the alcohol wipe (mine came dried out, so I used 70% isopropyl alcohol). Wave your hand around to pool blood into your fingers.3. Jab your finger with the spring-loaded lancet. I actually had a family member force my finger onto the spring-loaded lancet because I was too scared. It finally went off and laughed at the non-pain, “that’s all?”, LOL!4. Touch one of the four provided dabbers to your bloody finger and swirl it onto the water drop in one of the circles. Throw away the dabber and grab a new dabber (one dabber per circle, no mixing allowed).Right before your eyes you’ll either have a pretty even smear of blood, or the smear will very quickly start clumping (agglutination) right before your eyes.I’m sorry, but the results are positive.As you can see in my test photo, only Circle D (#3) clumped up.This means: no A, no B so I’m an O with a Positive Rh: so that makes me “Type O Positive”. I was actually hoping for type o negative because that’s the universal donor (and also the name of a really cool goth metal band).This allowed me to order the appropriate velcro tactical morale patches from Amazon. Let’s say I have one of these patches on a jacket, and a Charmin delivery truck driver shoots at some toilet paper hijackers and a stray bullet hits my arm: the hospital will pay NO attention to it and do their own tests, even when I say “don’t prick my finger, I already did an $8 test in my kitchen while sucking down a Red Bull during the great coronavirus shutdown of 2020! and I'm pretty sure I read the results correctly...wait, this *isn't* my jacket!”Why on Earth would you do such a thing?I hear this phrase a lot in my life, LOL!Nowhere in my medical records was my blood type listed.My doctors couldn’t tell me.I can’t donate blood (which is how most Americans learn their blood type).My doctor wouldn’t order a blood type test because there was no immediate need—and there’s no real use because if you need a transfusion they will retest anyway” since the consequences are so dire (imagine all your blood clumping like it does on the test card).Plus it was only $8 off Amazon, although two days later the price has been jacked up to $15 with Prime! This would be a cool project for a kid in school (take the test, document results, write a report).I did have a DNA test with 23&Me years ago and they said I was "probably" a type o, but they couldn't be sure. That blood type info has disappeared off their medical results page. I decided to see if it was true.Anyway…it seemed like a good idea at the time.*****UPDATE 2021: I had another surgery and this time they actually tested my blood (weird that they didn't for the previous surgery) and on my online medical chart it said I was Type O Positive: so this test kit worked and I have confirmed the correct result.
