A DIY Blood Typing Test! I always wondered what my blood type was, but never much had a chance to find out. I keep forgetting to ask my doctors when I do go in for the rare checkup, and my mother can't seem to decide what I am. She told me I was a type "O" one day, then changed her mind and said I was a type "B" a month later!
I decided I would find out for myself once and for all.
It's pretty simple, but a matter of a few drops of water and blood, and 40 seconds later, you know what your blood type is.
Key things to note:
- If you take the blood type test card out of its sealed foil wrap, you must use it within the day.
- Also, the automatic lancet is a one time use, I made the mistake of trying it out on a cardboard box, then having to make due with a sterilized knife point. Luckily, I had plenty of those at hand.
In other news:
It was 36°F in my room last night. I had a glass of coke with ice, and the ice was still there 4 hours later. The term "bed-warmer" now has much more meaning to me. I could really, really use one now.
