POLOKWANE – The volume of blood in a human body is approximately 7% of the body’s weight.
Today, the current blood stock is at 4.8 days. This might sound enough, but if you consider all who need blood, it is not enough at all.
Ipeleng Thetela, donor relations practitioner at The South African National Blood Service (SANBS) Limpopo, has encouraged residents to donate blood.
“The Polokwane SANBS clinic is open every day and we also have mobile clinics around the province. By donating blood you can help up to three lives as blood is separated into red blood cells, plasma and platelets,” she explained.
Blood is needed by mothers that give birth, cancer patients, trauma victims, for organ transplants and complicated surgical procedures.
Healthy blood cannot be manufactured by humans and therefore people have to donate blood.
Checklist for donating

There are four major blood groups namely A, B, AB and O. Each person is also classified as either Rh positive or Rh negative and therefore there are eight different blood groups namely: A+, A-, B+, B-, AB+, AB-, O+ and O-.
Not all blood groups are compatible with each other and the success of modern transfusion medicine depends on classifying and matching donors and patients correctly.
You can donate blood at the following places this August:
