Minimum Body Weight for Giving Blood
One of the requirements in donating blood is having a minimum body weight of 46 kg. Why should the donor's weight have to be at least 46 kg? Can it not be less than 46 kg? A person's weight affects the volume of blood that can be donated.
In 1 kg of body weight, blood that can be taken is around 8-10 mL. Because the average body posture of the Indonesian population is smaller than the population outside Indonesia, a minimum figure of 8mL is taken. If multiplied by 46 kg, the total volume of blood that can be taken is 368 mL.
Blood taken at the time of blood donation is at least 350 mL, in some cases up to 450 mL can be taken. If you weigh less than 46 kg, it can be risky for your health. Therefore, prospective donors must have a minimum body weight of 46 kg as a condition for blood donation.
