The minimum weight requirement for blood donors is typically set at 50 kg (110 lbs). This threshold is important for ensuring the safety of both the donor and the recipient. A donor must have sufficient body mass to tolerate the volume of blood that will be collected, typically around 450-500 ml. Weighing at least 50 kg helps to minimize the risk of adverse reactions such as fainting or hypotension during or after donation. Furthermore, individuals below this weight may not have enough circulating blood volume to sustain their health after donation, which underscores the significance of this requirement in blood donation protocols.
