Weight 50 kg, that allowed to excrete amount that does not exceed 10% of blood volume in the human body. (In women - 5 liters, in men - 6 liters).
Be sure to eat something light before donation and drink before and after donation. 50% of the blood volume is fluid, as soon as blood is donated, fluid is lost but by the amount of drinking lost back to the human body. If you feel bad right after the blood donation, a team of blood donors is skilled and experienced to treat such cases. (Fainting occurs not only in the absence of fluid. Occasionally an involuntary reaction)
According to the Hebrew or the Gregorian date.
Blood can be donated from age 17 to 18 with parental approval and age 18 without restriction. A parent signing form can be downloaded from here.

Your blood is checked and, after being found fit, sent to hospitals for life-saving purposes.
Pinch yourself and count to 3 and that's basically the pain. What is this pain compared to saving a human life by donating a blood dose by you?

Every three months.

This amount is up to 10% of the blood volume in the human body, this is the amount that can be taken from a healthy donor without it harming him. 50% of the blood volume are fluids that the blood donor returns to himself after drinking. The red blood cells regenerate within eight weeks, the body does not feel their lack.
The fundraising kit is sterile, the disposable needle, which is not transmitted from person to person, so there is no fear that you will be infected with any disease as a result of the fundraising operation.
Up to 20 minutes including registration, short questioning, blood pressure and hemoglobin tests and the donation itself.
All doses are tested for AIDS. The blood donation is not intended to provide answers. A person who fears that he has contracted AIDS is asked to undergo an examination at the designated centers and the workers in the large hospitals around the country. Do not donate blood to be examined, since there is a period of incubation (the "window" period) from the time of infection to finding the antibodies in the blood that can be detected in the tests. The blood services are meticulous about the quality of blood transfusions because, as is well known, the blood transfusions are transferred to a patient in a hospital requiring a dose of blood to save his life. If the answer is positive the donor is invited to the blood services for the message. The information is also forwarded to the Ministry of Health. MDA blood services can be found Only blood type.
Six months. Since there is no supervision and control over how to perform the tattoo and / or piercing and there is a danger of contracting hepatitis, AIDS and other diseases.
Two hours. At the time of contribution the blood oxygen level decreases and then basically smoking can interfere with that as is known while smoking the oxygen level decreases.
If the cause is inflammation - wait for 3 days after antibiotic treatment. "Acne" - in most cases there is no problem, but ask the person responsible for this.
Types of blood, AIDS, hepatitis B, C, syphilis (syphilis), antibody survey.
If you feel good, there is no problem.
6 should wait months after birth before blood can be donated again.
Allowed - if you have not had a seizure in the past week and if you do not take steroids. Inhaler - allowed.
Anemic people are not allowed to donate blood, anemia - refers to those people whose level of iron is low, which can be found in the hemoglobin test. Therefore, the permissible values ​​for the donation are: 12g-16g% white - 13g-18g.
It has nothing to do with it. The insurance you receive at the end of the blood donation is from Magen David Adom and provides coverage for blood donations when needed for you and your immediate family (parents, grandparents on both sides, brothers and sisters up to the age of 18) for one year.
In an emergency, when your life is in danger, there is no doubt that you will receive the necessary blood doses, but the hospital will ask you for a refund. In order to prevent running around and asking for good from friends and family, it is worth donating blood as part of MDA and being insured.
With the approval of parents who will be distributed to you at the end of the information campaign, the free telephone number of MDA is available, where you can find out the hours of operation at the MDA branches and choose to donate blood at the nearest MDA station.

    1. Blood donors organization

      Hadas Shalom,
      Regarding 1 - If you have no side effects there is no problem donating blood.
      Regarding 2 - ask her doctor
      Regarding 3 - the system does not display the references automatically. They need to be approved. You probably had an abnormal face for some reason. This time you sent 6 times in a row. This is also a reason for blocking and deleting.
