The first step in blood donation is data collection, a credible identification of the blood donor, which will require the personal identity card, address card and the health insurance (TAJ) card. In the absence of these, unfortunately the blood donation cannot advance.
Documents required for the identification of foreign nationals:
- Photo identification document (ID): passport or ID card issued for personal identification by the authority of the country of citizenship with an identification number
- Document certifying the health insurance coverage with an identification number.
Document required for registration of a foreign residence:
- A card issued by authority of the competent country containing the name and residential address of the donor.
Recording the mailing address of persons living abroad:
- The contact details in Hungary provided by the blood donor, which contain enough information to send a postal letter.
After the data collection, a questionnaire putting questions regarding their lifestyle, illnesses and medication habits must be filled in by the blood donors. If anything is unclear, feel free to contact our colleagues with confidence.
The next step is a medical examination. First, we pierce the fingertip is to check the hemoglobin level, and in the case of first blood donation, a preliminary blood group determination is also performed. Blood pressure and heart rate will then be measured followed by evaluation of the responses to the completed blood donation questionnaire and the results of the tests in order to eligibility for blood donation to be determined by the examining physician.
If the examining doctor does not find the blood donor eligible for donating blood, then he or she will inform the donor of the reason and duration of the screening out, which may be temporary or permanent.
If the doctor finds everything all right, the blood donation will follow.
Blood is given in a semi-sitting or lying position, after arm disinfection, from the elbow vein most suitable for blood collection. Our assistants perform up to 2,500 vein stabs a year therefore it is not more than a perception of a nail biting. After piercing the elbow vein, the first 20-30 ml of blood is transferred to the sampling bag - part of the collection bag, from which the content of sample tubes required for subsequent laboratory examination is taken.
Next to the bed there is a small swinging device, this is a balance-shaker that allows you to measure the blood taken and mix it continuously with the anticoagulant solution.
5-6 liters of blood circulate in the body of an adult, of which approximately half a liter is reserve. During a blood donation, 450 ml (± 10%) of blood is taken therefore this amount can be easily replenished by the body.
The blood donation itself takes 5 -12 minutes only.
A disposable, sterile, multi-part bag system is used to draw blood in order to produce a closed system blood product. This means that during the preparation of blood products, the blood taken is completely isolated from the environment; nothing can get into the bag system. The blood bag is not empty, contains anticoagulants, and solutions required for proper cell function during storage.
Following blood donation
At the end of the blood collection, a sterile pressure bandage is applied to the puncture site, followed by a 5-10 minute rest on the blood collection bed.
Do not remove the pressure bandage for 4 hours and be sure to eat and drink plenty of fluids after donating blood!
Do not perform strenuous activities on the day of the blood donation!
