"Only 4 star due to invalid test.. (probably my fault) But other than that it seemed okay. Has instructions on what to do, a step by step. I highly suggest you read them before opening anything 🤣 Make sure nobody bumps into you and siblings stay in other room or it’ll look like my sons card 🥴 also I didn’t have the patience.. I possibly put too much blood and wouldn’t try quick enough before putting the sticker on top to secure it.."

For the longest time, I didn't know what my blood type was. I've never donated and never asked that question during routine lab work. So rather than continue to question, I opted to learn for myself in the event I ever needed to know for myself. Simple and straight forward with very easy to follow instructions, I found out my blood type in just a few minutes! I spent my whole life questioning if I was A+, but turns out? I just needed to stop B-. Ah? Ah?? Sorry, Dad joke. But seriously, I keep the little card laminated in my wallet in the event if I ever need plasma or blood. You can never be too careful or prepared! I'll be making plans to donate and keep some of my own in storage just in case. (Yep, you can do that. Science is cool.)savannah

Got the tests so we would know our blood types in a medical emergency. The procedure was simple and straightforward, and the tool for pricking your finger was easy to use and not painful beyond the basic prick.Just make sure you record the results, we had to retest because we didn’t record the resultsmichelle kirby
This worked great and it was simple.
