May 13, 2023

Blood donation is an individual's contribution to society and a guarantee of safety for their future accidents. Therefore, many people have the experience of donating blood, but some people are eager to donate blood, and the blood test says that the blood is not qualified and does not allow the full amount of blood to be tested, so here is a look at what is the reason for the failure to donate blood
