Misconceptions about Blood Donation


According to the rules of the World Health Organization, all people in good health can donate blood voluntarily.

However, there are some conditions that can lead to misconceptions about blood donation.

Here are some of the confusions being explained.

Vegetarians cannot donate blood voluntarily:

This fear is based on the level of iron in the blood. Vegetarians are thought to be low in iron. But if you eat a balanced diet regularly, there can be no reason to have less iron in your blood.

However, if your blood is really low in iron, you will not be allowed to donate blood for safety reasons. In most countries, hemoglobin is tested before blood donation to determine if the donor is suffering from anemia.

Cannot donate blood if ill, pregnant, child or elderly:


This is true. People who are HIV positive (infected with AIDS), hepatitis, syphilis, TB, and some other blood-borne diseases cannot donate blood.

Cold, flu, whooping cough, stomach upset but can’t donate blood.

You will be allowed to donate blood after 14 days of complete recovery from any illness.

If you are taking antibiotics, you can donate blood seven days after the end of the course.

Other countries have different rules for other medicines.

If you are pregnant or breastfeeding, breastfeeding, or if you have had an abortion, you will have to wait for a blood donation until the iron levels in the blood return to normal.

The minimum age for blood donation is 18 years. In most countries, young people of this age need parental consent to donate blood. Young people of this age are also at higher risk of losing consciousness while donating blood.

There is no maximum age for regular blood donors. In some countries it is 60-70 years.

In countries where life expectancy is low, for the first time, blood donors need to be careful.

Risk-taking activities that hinder blood donation:


There are various risks in life. They can be a problem for blood donation.

The World Health Organization says that ‘risky sex’, such as polygamy, sex for money, homosexuality, etc., can create problems in blood donation. In this case, blood donation is allowed only after examination. Those who are intoxicated by injection, they can not give blood.

In countries where there is an outbreak of mosquito-borne malaria, dengue and Zika virus, there are restrictions on taking blood from anyone coming from there.

Many countries do not accept blood from those engaged in these ‘risky’ activities. In this case, however, a broad-based ban could create inequality.

Considering the weight of the body, an adult human body has an average of five liters of blood. 500 ml of blood is taken in each blood donation session.

It is difficult for gay men to donate blood voluntarily due to strict restrictions.

Women can also donate blood during menstruation.
