Frequently asked question

Contenu

The goal of the height and weight criterion is to ensure that no more than 18% of a donor’s estimated blood volume is collected. 

Adverse effects are more likely to occur in donors with a lower blood volume.

For this reason, weight and height are factored in to determine whether you are eligible to donate.
