Does drawing blood for tests invalidate the fast?

The questioner : Yes. This is a set of questions. The first one says: In the name of Allah, the Most Gracious, the Most Merciful. Peace be upon you and Allah's mercy. I went to the hospital, and they required drawing blood for analysis during the fast. Does this invalidate the fast?

The Shaykh : In the name of Allah, the Most Gracious, the Most Merciful. Drawing blood for analysis does not harm the fasting person in any way, because it is not the same as cupping, and the default is that the fast is valid. Likewise, extracting a tooth does not affect the fast, but if he extracts his tooth, he must not swallow the blood, because blood is forbidden, as we read a little while ago. Likewise, if he has a nosebleed, it does not harm him in any way. And if he is injured in any part of his body, it does not harm him in any way, even if the blood is abundant, because this is not by his choice. Yes.
