The amount of blood taken in a single blood draw typically ranges between 10 to 20 milliliters, depending on the tests being performed. On average, this amount of blood is collected in one or two vials.
While one or two vials of blood rarely poses any short-term risk, it is important to be aware of any signs of adverse reactions that may occur after such a draw. Generally, a single individual’s body should never have more than 10 vials of blood taken within one week’s time, nor more than 50 vials of blood over the course of a year.
Anything beyond that is considered too excessive, and could put a person at risk for severe health complications.
