I want to donate blood, but I only weigh 105 pounds. Are there any places that let you donate even if you weigh less than 110 pounds?

Unfortunately, no. Current FDA guidelines require all volunteer blood or compensated plasma donors to weigh at least 110 Lbs (50 kg).
In the U.S., the majority of blood donations are collected in 500 mL bags. FDA guidelines allow for a maximum of 10.5 mL/kg body weight to be collected, which works out to 500 ml whole blood plus 25 ml for FDA mandated screening tests. This volume represents approximately 12% total blood volume in a 50 kg donor. Studies have shown that as blood loss approaches 15%, there is a significant increase in donor reactions (fainting, shortness or breath, nausea, vomiting, seizure activity). This weight/volume was chosen to both protect the donor and provide an efficacious blood product for the recipient.Source(s): Medical Director - regional blood center
