Contraindications for donating blood – who can and who cannot become a donor

1 6 - 9

Donated blood is a very popular product. Transfusion of blood or its components is required for most patients with injuries, burns, during recovery from surgery, especially organ transplants and cesarean sections.

In addition, there are a number of diseases that require transfusion of blood, plasma, or certain blood cells.

The situation is complicated by a number of factors:

  • Russia is sorely lacking donors. With the WHO norm of 40 donors per thousand of the population, in Russia this figure is only 14 people.
  • At the first donation, the blood is quarantined for several months. Only if HIV and other dangerous infections are not detected in it during repeated analysis, donated blood can be transfused to patients. For this reason, the surge in donation after large-scale accidents does not fundamentally change the situation.
  • Blood of the required group is not always available. For example, the fourth negative is very problematic to find: only 13% of people with group IV live in the world, of which people with negative rhesus make up a couple of percent at most.

What is donated blood used for?

In its pure form, it is rarely poured over. Basically, patients require individual components and preparations based on human blood. Therefore, after the fence, it is divided into components.

ComponentWhen and how is it used?
Whole bloodIt is in demand with large blood loss as a result of trauma or surgery
PlasmaIt is necessary for patients with burns, weakened and people with reduced immunity. Plasma contains many nutrients and antibodies, so it can actually become a substitute for the immune system for those who have taken immunosuppressive drugs for a long time, or who have weakened immunity after serious treatment.
ErythrocytesRed blood cells. Necessary for patients with anemia, cancer of the blood and bone marrow. Red blood cells can be donated as a separate component. Typically, robust male donors are selected for red blood cell donation.
PlateletsCells responsible for blood clotting. They are transfused to patients with hemophilia and those who have undergone chemotherapy.
GranulocytesA type of white blood cell – white blood cells. Transfused for patients with severe infections and infectious complications. Granulocytes do not last long: they can only be transfused within a few hours after donation.

Who are donors?

glav - 11These are people who voluntarily donate their blood or blood components for transfusion to other people.

There is also the concept of autologous donation – the components are taken from the person himself before the course of treatment or planned surgery.

After the intervention, the body is weakened, foreign cells are a great stress for it. Therefore, doctors insist on the transfusion of the patient’s own donor material in cases where it is possible.

Donors are one-time and permanent. The first donate blood once – help is needed for a relative, acquaintance or as assistance to victims of a large-scale accident. Continuous donation involves several donations per year.

On average, the human body contains from 4,5 to 5,5 liters of blood. Its volume increases and decreases with fluctuations in body weight. For one procedure, you can take no more than 12%. Typically a serving is 450 ml.

Who is not allowed to be a donor?

The list of contraindications is quite large. People with serious blood diseases, oncology, infections cannot donate blood for donation at all. In addition, there are situations when a person has a temporary withdrawal from donation (for a period of one month to three years) – due to past diseases and other interventions.

In some cases, contraindications may be conditional. For example, if we are talking about the urgent saving of the life of a close relative with whom there is full compatibility – but the potential donor has a temporary recusal. In the absence of an alternative, the doctor can weigh the pros and cons and make an exception if the potential risk is not high.
