  • Why diabetics cannot donate blood?

    The diabetic who cannot donate blood is that which we call insulin-dependent; ie, one who needs insulin to keep your metabolism sugar close to normal. These patients have significant changes in the cardiovascular system and, accordingly, during or after donating blood, they may have some reaction to the worsening state of their health.

  • Why people weighing less than 50 kg cannot donate blood?

    The total volume of blood to be collected is directly related to the donor's weight. For men not exceed 9 ml per kilo and for women, 8 ml per kilo. This anticoagulant in the collection bag binds to blood prevents the blood from clotting. The volume of anticoagulant bag is standardized to a minimum of 400 ml of blood. So, a person weighing less than 50 kg could not donate the minimum volume.
