I've always wanted to know my blood type, but I don't weigh enough to donate blood, and I don't want to go to the doctor's office to see what my blood type is. I want something I can afford, something I can easily make at home. I saw some YouTube users use the test, so I bought it myself, and I got this in my email, and it was well sealed. The test card itself is air-sealed. The Lancet has a plastic rod that you must remove before you use it. The small white bar is placed in a small Ziploc bag. The explanation is simple, but I actually put too much water on the section, so I'm a little worried. You only have one chance, and it's simple, but I can see that some people have to order more than one test. Fortunately, everything went well and I got the result I wanted. The Lancet did make me anxious, but after trying other ways to make myself bleed, I felt depressed and ended up with no problem using the Lancet. It doesn't hurt at all, it's just a quick tingling. I found these little white sticks not very easy to use. This test requires you to provide at least 4 drops of complete blood from a small Lancet stab, which is quite difficult! I did bleed enough, but it just soiled my fingers and didn't want to fall on the stick. The sticks seemed to almost repel the blood, but I got a little there and just daubed it during the test. The extra water I ended up putting on the test actually worked well for my lack of blood.
