Blood is sometimes called a vital fluid because it provides the nourishment to all body organs and tissues and carries away waste materials.
It depends what kind of blood work they are taking. If they are taking blood for donating they wouldn't allow it and who would want to take that blood. Everyone has a one of a kind type of blood even down there. The blood is kind of "shed" from the uterus and everyone is different. So they could take it for blood work but it depends what kind of blood work.Thank you
