How heavy do you have to be to donate blood?

Answer 1

There is not a set minimum. There are height brackets, and you have to exceed the minimum weight in your heaight bracket.

A bit more:

As an adult you have to weigh a minimum of 110 pounds.

Answer 2

There are age, weight, and health requirements that an individual must meet before they can donate blood to ensure safety, both their own and the potential recipients, too. An under-weight person could be at health risk if they lose blood, even through donation.

Answer 3

In the U.S., FDA guidelines allow a maximum of 10.5 ml/kg body weight to be collected. The majority of blood collection facilities use 500 ml collection sets, with up to an additional 50 ml allowed to be collected for required screening tests. As such, a lower weight limit of 50 kg (110 lbs) is mandated.

Answer 4

This is because if you don't weigh enough, the amount of blood they have to take for a blood donation is too much for a small body like that. beachball45
