Surprising factors that stop you from donating blood

Donating blood can save many lives. However, not everyone is eligible to do this.


You are under medical treatment:

According to Reader's Digest, some medicines you are taking may take your time to wait after the last dose if you want to donate blood. If your infection is being treated by antibiotics, doctors may ask you to wait until you are totally healthy. If you are taking aspirin or any aspirin-containing medicine but still want to donate blood, you must wait 2 days after stopping the medication. 


You have recently been vaccinated:

According to Dr. Thomas Hirose, Director of Saddleback Memorialcare Medical Center in California, some vaccines may contain live infectious agents, which do not allow you to donate blood for a certain period of time. For example, you have to wait at least 4 weeks after your vaccination with measles, nerve shingles or chickenpox to be ready for the donation. 


You have got unsafe tattoos:

Many tattoo shops do not comply with the standard like properly disinfecting needles, or not reusing ink for other customers. That’s why you have to wait at least 12 months after your tattoo is done if you want to donate blood. If not, the receiver may be infected. In addition, ear piercing also causes the same problems just like tattoos. 


You have got positive result for hepatitis or HIV test:

HIV and hepatitis can be transmitted through blood, you cannot donate blood if tested positive for these 2 diseases. Some types of hepatitis can be untreatable, leading to serious health problems, such as liver failure or even liver cancer. 


You have just traveled abroad:

As a requirement during the registration process, blood center staff will ask if you have traveled abroad recently, if you have a blood infection or any kind of infectious diseases. For example, in the last 3 years, if you have been to an area at risk of malaria, you might have to wait a certain amount of time before donating blood. If you have spent a long time in the country with mad cow disease, you are not eligible to donate blood. 


You are underweight:

People who are underweight tend to have low blood volume, and therefore, cannot tolerate the blood removal. Each country has a certain weight regulation for blood donors. 


You feel unwell:

If you feel tired on the day of the blood donation, whether it's a cold, sore throat or headache, it's best to stop giving blood. You need to wait at least 48 hours after those symptoms disappear. You definitely need a good health when donating blood. 


The iron content in your body is too low or too high:

The amount of iron below 12.5 g/dL for women and below 13 g/dL for men will make you ineligible to donate blood. For this reason, regular blood donors, especially women, are encouraged to take iron supplements and eat iron-rich foods to keep this amount in the normal range. In addition, you cannot donate blood if there is too much (over 18 g/dL) iron in your body. It increases the risk of heart disease, heart attack, stroke and some cancers. 


You are pregnant:

Although more blood circulates in human body during pregnancy, women need to wait at least 6 weeks after giving birth to donate blood. You also need to make sure that your body is healthy throughout your pregnancy. 


You have syphilis:

If you have syphilis, you must wait at least 12 months after the final treatment to donate blood. This is an infection that can spread easily. In particular, it can recur and cause permanent health problems.
