Question
I did blood tests a few months ago and found that I was deficient in vitamin D. I have been taking the vitamin for a while, and now I am interested to see if it has really increased and by how much. The question is, am I allowed to do a blood test just out of curiosity, or is it perhaps considered "harming oneself"? Thank you very much!!
Answer
Hello,
There is no problem with this. Since if there is any need for a person to cause harm, there is no prohibition at all.
[Note: The Shulchan Aruch did not rule a prohibition against harming oneself].
