Eldoncard Blood Typing Kit, 2 Test Pack, Know Your Blood Type, Accurate Instant Home Testing, Determine A, O, B, Rhs-D Negative & Positive Groups

These were super easy to use and extremely helpful in determining me and my husband’s blood types! The instructions were easy to follow and it didn’t take very long for the results, maybe 5-10 minutes. They were also accurate as my husband already knew his blood type but wanted to take the test anyway.. classic. Would definitely recommend this product for anyone curious or needing to know their blood type! Could be super helpful down the road, too!

It does what it says it is supposed to do. It is quick and easy to use. It is also accurate

Works like a dream. I knew my blood type from being tested when I was pregnant but wanted to know my husbands and daughters. Tested myself to be sure it worked and sure enough, came up spot on. Tested both my husband and daughter and they worked fine. My 9 year old handled the skin prick part fine (and she HATES needles) and was super intrigued behind the “mad scientist experiment” (her words) that we were doing. She was also happy that she has the same blood type as me. My husband is also happy as he finally knows what his is too. Just take care when doing the test to ensure you don’t put your fingers near the test areas or get blood mixed up in the wrong ones. We did the first time which made one test null. Take time to get everything laid out and read the instructions!

It was easy to use.

Works exactly as described. I only had to perform one test and I got a very clear A Positive result. Instructions were crystal clear and easy to understand. My guess is that most of the negative reviews were due to a couple of reasons-- 1. You didn't read the instructions. 2. You accidentally contaminated your reagents before you got started. To avoid the latter mistake I would recommend not writing on the card until after you perform your blood typing steps. Be very careful when you handle the card. Do not touch the circles with your hand or anything else, as oils from your skin will contaminate and ruin the reagents on the card. Having a friend or loved one act as your nurse will help a lot too, as you may find it difficult to extract enough blood for all four reagent circles from your finger before clotting occurs. Having a dedicated nurse to handle blood collection while you massage blood flow towards your finger will help with this step. And lastly just make sure you don't allow the blood/water mixture to exceed the lines of the circle when you are tilting the card during your final 'curing' steps. Don't tilt the card straight up and down, but rather at a slight 30* angle. Follow the instructions explicitly and you will do just fine. Interpreting the results was very easy for me. You can see from my picture that the first reagent displayed a typical reaction, the second reagent displayed no reaction, the third reagent displayed a strong reaction, and the fourth reagent (control) displayed no reaction. This result means I'm A (from typical reaction on the first reagent) Positive (from strong reaction on the third reagent).

Accurate results when instructions are followed - easy to follow with clear images of what blood typing results should look like, which appeared fairly quickly from my testing. A, B, and O types and Rhesus (Rh) factor testing only. The safety lancet is easy to use to retrieve blood. Kit comes with 2 lancets, 1 test card, 4 blood sample sticks (control and 3 blood types) for collection and mixing with water from included pipette, alcohol swab, and laminating sheet when card has completely dried. I did 2 tests to see if results could be duplicated, which they were.

Ordered the 2 pack but just one arrived. Works ok otherwise

Very affordable way to find out your blood type without going to donate blood. Very easy to use. Just have to follow directions. Great quality and price
