What is the minimum hemoglobin concentration required for a male blood donor?

The minimum hemoglobin concentration required for a male blood donor is typically set at 13.5 g/dL (135 g/L). This threshold is established to ensure that donations do not adversely affect the health of the donor, as having sufficient hemoglobin is critical for maintaining adequate oxygen transport in the blood.

In the context of blood donation, the donor’s hemoglobin level is carefully evaluated before the donation process to prevent complications such as anemia or fatigue post-donation. Male donors generally have a higher baseline hemoglobin level compared to females due to differences in body composition and physiological factors. Thus, the requirement for males is more stringent to safeguard their health while ensuring that there is still a sufficient supply of blood for transfusions and other medical needs.

Setting this threshold helps maintain a safe and effective blood supply while ensuring donors can recover quickly after donation.
