Blood donation: who are those who can not give it?

There are often blood donation campaigns. We invite everyone to give some. Because the blood, remember, can help save hundreds of lives. There is also a blood bank that needs to be constantly renewed. Because the plasma has an expiration date and therefore can not be stored for life even if it has never been used. How do you know if you can become a blood donor? Because yes, some people, despite their goodwill, can not donate their blood. Here is a list of those concerned.
   
Who can not give blood?
People who weigh less than 50 kilos
It is not allowed to give blood if you weigh less than 50 kilograms. Because a person with a lower weight could not stay healthy once it was extracted 450 cc of blood. For the safety of the donor, these donations are prohibited.

People who donated less than 2 months ago
Blood donations can be made every two months, provided you are in good physical condition and meet basic requirements. But if a person gave blood less than 2 months ago, they can not donate blood again because the minimum period has not passed yet. To know that during each extraction, one loses 450 cc of plasma and our body recovers them during the last weeks. Overall, only 4 so are allowed per year.

People who suffer or think that they are suffering from an infection
Before being sent to the blood bank, the blood is analyzed 24 hours after the extraction to check for the existence of infectious diseases ( hepatitis   B and C, HIV, syphilis) and so that they are not transferred to other patients. It is good to know that an infection can not be detected during the analysis if the person is in the period of the window, that is to say the time elapsed between the infection and the appearance of the virus .

For example, if you have had unsafe sex and think you may be infected, avoid donating your blood for the safety of everyone. At least until a doctor tells you that you have nothing after a blood test. 

People who have a piercing or a tattoo of less than 4 months
Many people believe that people who have piercings and / or tattoos can not donate their blood, which is totally wrong. There are, however, special cases where they can not donate their blood. That's when they had a piercing or tattooing less than 4 months before the blood donation. During this time, it is possible to detect serious infectious diseases that could have been transmitted during the use of a contaminated needle, such as HIV or hepatitis. For this reason, it is necessary to wait 4 months or more before being a donor.

People who suffer from serious chronic or infectious diseases
Because of the suffering they cause, some sexually transmitted , chronic, or infectious diseases prevent them from becoming blood donors. So, if you have one of these diseases, you will refrain from donating:

Diabetes dependent on insulin
Hepatitis B
Hepatitis C
Syphilis
HIV
Pregnant or lactating women
It is only after the period when they have finished breastfeeding that they can become blood donors. Women who have undergone major surgery must wait 4 months to make a donation. And in the case of a minor operation, a week.

If you find yourself in one of the cases mentioned, you now know when and why you can not give your blood. Do not hesitate to share this information around you to inform your entourage.
