Who is a donor and why is their blood needed

A donor is a person who voluntarily donates their blood for transfusions to other people. Blood is needed: in cases of trauma with blood loss (traffic accidents, disasters); during operations; in difficult births; for patients with hemophilia, leukemia, aplastic anemia; for patients with burns; in the treatment of cancer (chemotherapy suppresses hematopoiesis). Donor blood is also used to produce medicines (albumin, immunoglobulin). One dose (450 ml) can save up to three lives. The demand for blood in Russia is about 1.5 million liters per year. It is provided by volunteers.

Blood groups and Rh factor: why it is important

Human blood is divided into 4 groups (0/I, A/II, B/III, AB/IV) according to the ABO system and into Rh-positive (Rh+) and Rh-negative (Rh-). A match of blood group and Rh factor is necessary for transfusion, otherwise the recipient's immune system will destroy the donor's erythrocytes (hemolysis), which can lead to death. The universal donor is group 0(I) Rh- (negative), but there are few such people (about 7% of the population). The universal recipient is group AB(IV) Rh+. Knowing your blood group is important not only for donation but also for emergency situations. You can determine your blood group at a polyclinic or when donating blood.

Who can be a donor

Requirements: age from 18 years; weight not less than 50 kg; absence of chronic infectious diseases (HIV, hepatitis B and C, tuberculosis, syphilis); absence of oncology; normal blood pressure; not pregnant or breastfeeding; no severe cardiovascular diseases; no tattoos or piercings in the last year; no illness in the last 2 weeks; no alcohol consumption for 48 hours, no smoking for an hour before donation. Temporary exclusions: menstruation, taking antibiotics, after surgery, after vaccination. The full list of contraindications is provided by the doctor.

How the blood donation process goes

Process: come to the blood transfusion center or station; fill out a questionnaire; donate blood from a finger for hemoglobin; examination by a therapist. Then you are seated in a chair, blood is taken from a vein (450 ml) in a sterile system with a preservative. Everything is disposable. The donation time is 10-15 minutes. After that, rest for 15 minutes, sweet tea, cookies. Two to three days later, the blood will be tested for infections (HIV, hepatitis, syphilis) and allowed for transfusion. If an infection is detected, the donor is placed on a registry and no longer allowed to donate. Donating blood is safe because everything is sterile.

Types of blood donation

Whole blood (standardly 450 ml). Plasmapheresis - take blood, separate the plasma, and return the cells to the donor. Plateletpheresis - collection of platelets (needed for oncological patients). Erythrocytapheresis - collection of red cells. You can also donate granulocytes (for immunodeficient patients). Each type has its own requirements and duration. Plasma and platelets are the most in demand.

Why blood donation is safe

The needle and all systems are disposable, the risk of infection is excluded. The volume of collection (450 ml) is 10% of the total blood volume (4-5 liters). The body restores the lost volume in 1-2 days, cells in 4-6 weeks. Hemoglobin is checked before donation. If the hemoglobin is low, it is not allowed. After donation, it is recommended to drink plenty of fluids, iron-rich diet (rice, apples, liver). Side effects: dizziness (rarely), bruise at the puncture site, weakness. Serious complications are rare.

Benefits and incentives

In Russia, donors who have donated blood 40 or more times receive the title "Honorary Donor". They are entitled to: an annual monetary payment (about 17,000 rubles); priority treatment in state institutions; preferential sanatorium tickets (with indications); paid day off on the day of donation. Regular donors receive a certificate for 2 days off (the day of donation and the next day), monetary compensation for food (about 5% of the subsistence minimum). In some regions, additional benefits (discount on utilities, free travel). In other countries, their own bonuses.

Myths that hinder blood donation

Myth 1: you can get infected. Refuted above. Myth 2: donation weakens the body. Regular donation stimulates the renewal of blood, increases immunity. Myth 3: gain or lose weight - no. Myth 4: it hurts no more than a regular shot. Myth 5: you cannot have tattoos - you can, a year after application. Myth 6: donors have lower blood pressure - temporarily. Myth 7: blood donation is contraindicated for vegetarians - if the hemoglobin level is normal, it can be.

How to become a donor and where to donate

Find the nearest blood transfusion center or a mobile campaign. In Russia, the map of donation points is available on Yandex.Maps or on the "I am a Donor" portal. Usually, you need to make an appointment by phone or through state services. Take with you: passport, policy, SNILS. Do not have a heavy breakfast, sweet, eggs - better to drink tea with cookies. Rest well before donation. On the day of donation, do not smoke and take medications containing aspirin.

June 14: the history of the holiday

World Blood Donor Day was established in 2004 by the World Health Organization, the International Red Cross and Red Crescent Federation. The date is timed to the birthday of Karl Landsteiner (1868), an Austrian immunologist who discovered blood groups. The celebration aims to attract volunteers and increase the safety of blood. The slogan for 2026 is "Donate blood, donate plasma, share life".

Become a donor. It's simple, safe, and very needed. You will not know the name of the person you are helping, but they will be alive. And perhaps one day you will be in the position of the recipient. Blood cannot be bought at a pharmacy. It can only be given by a person.
