Procedures for donating blood and one of its most important components - plasma, differ in terms of the process of extraction and influence on the human body. However, for both procedures there are certain restrictions on the frequency of donating material.

Blood donation

One submission from a donor is usually removed about 450 milliliters of blood. This is quite a serious blow for the body, so the donor needs time to recover the lost blood cells. In addition, note that the speed of this recovery will be different for different people.

So, the current restrictions on the number crocodoc during the year differ for men and women. Men are allowed to donate whole blood up to 5 times a year, women - 4 times a year. In addition to the compliance with the total number of visits of points of blood sampling are commonly regulated and the intervals between subsequent krovotechenie.

So, after another blood experts recommend the next time you visit the doctor for delivery not earlier than 60 days. Thus once the donor has carried out five crocodoc in a row, it is advisable to make a longer break, lasting 3-4 months. This will not only restore the normal state of the circulatory system of the body, but also to provide high enough quality characteristics of the donor material.

Delivery of plasma

The procedure of putting the plasma somewhat more difficult in comparison with blood, so it usually takes more time. So, if the process of drawing blood usually takes about 10-15 minutes, the fence of the plasma will require about 40 minutes.

This is because in the process of fence plasma in the donor after removal of portions of the whole blood, it is separated from the plasma, and the remaining components with the help of special equipment is returned to the donor organism. This causes less negative impact on it due to the fact that the workload associated with the subsequent recovery, will be somewhat lower.

Accordingly, the allowable frequency of delivery of plasma to the donor will be higher in comparison with the procedure of passing the whole blood. So, to donating plasma without harm to the body can be 6 to 12 times a year. After each donation, you must provide a break of sufficient duration that provide complete recovery of the body. Experts believe that the duration of such break shall be not less than 30 days.
