Eligibility for Blood Donation Who Can and Who Cannot Donate

Blood donation is a vital part of the healthcare system. It is the process of giving blood to help people who need it for medical reasons. There are many reasons why someone might need a blood transfusion, such as surgery, trauma, childbirth, cancer treatment, or anemia. According to the World Health Organization, every year, millions of people benefit from donated blood. In this article, we will discuss the eligibility criteria for blood donation, who can donate blood, and who cannot donate.

Who are Eligible to Donate Blood?

Eligibility for Blood Donation Who Can and Who Cannot Donate

Blood donation is a selfless act that can save lives. Before donating blood, individuals must meet certain eligibility criteria to ensure the safety of both the donor and the recipient. Here are some general guidelines for eligibility:


Most countries have a minimum age requirement of 18 years old. However, some countries allow 16-year-olds to donate blood with parental consent. The upper age limit for blood donation varies between 60-65 years, depending on the country’s regulations. This is because older donors may have underlying health conditions that could affect the safety of their blood.


To donate blood, one should be at least 50 kg (110 pounds) in weight. This ensures that the donor has enough blood volume to donate without experiencing any adverse effects.


Donating blood requires good overall health. Individuals with conditions like diabetes, high blood pressure, or heart disease may not be eligible to donate. Additionally, if you have any current infections or taking certain medications, you may be deferred from donating temporarily.

Hemoglobin Levels:

Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body. The minimum hemoglobin level for blood donation is usually 12.5 g/dL for women and 13.0 g/dL for men. This is to ensure that the donor has enough hemoglobin to donate without becoming anemic themselves.

Travel History:

Some countries have restrictions on blood donation from individuals who have traveled to areas with a high risk of infectious diseases, such as malaria or Zika virus. This is to prevent the transmission of these diseases through blood transfusions.

Who Can Donate Blood?

The eligibility criteria for blood donation may vary slightly from country to country, but here are some general guidelines for people who can donate blood:

Healthy Individuals:

The most important factor for blood donation is good health. If you are in good health and meet all the other eligibility criteria, you can donate blood.

Regular Blood Donors:

If you have donated blood before and have been deemed eligible, you can continue to donate regularly. Regular donors are essential for maintaining an adequate supply of blood for patients in need.

Group O Blood Type:

People with type O blood are known as universal donors as their blood can be given to people with any blood type. Therefore, they are highly encouraged to donate blood as their blood can be used for emergency transfusions.

Negative Blood Types:

Individuals with Rh-negative blood types (A-, B-, AB-, O-) are also encouraged to donate as their blood is less common and in high demand for certain medical conditions.


Smoking can affect the quality of blood and increase the risk of complications during and after donation. Therefore, non-smokers are preferred as blood donors.

Who Cannot Donate Blood?

While blood donation is a selfless act, not everyone is eligible to donate. Some people are permanently deferred from donating due to various reasons, while others may be temporarily deferred. Here are some reasons why someone cannot donate blood:

Underlying Health Conditions:

Individuals with chronic illnesses like HIV, hepatitis, or cancer are not eligible to donate blood. Additionally, if you have had a heart attack or stroke in the past, you may not be allowed to donate blood.

Recent Surgery or Medical Procedures:

If you have had surgery or any medical procedure recently, you may need to wait for a certain period before donating blood. This is to ensure that your body has fully recovered from the procedure and can handle blood donation safely.


Some medications can affect the safety of donated blood. If you are taking medications like antibiotics, blood thinners, or steroids, you may be temporarily deferred from donating blood.

Pregnancy or Childbirth:

Pregnant women and women who have given birth in the past six months are not eligible to donate blood. This is because pregnancy and childbirth can lead to a temporary decrease in blood volume and iron levels.

Lifestyle Choices:

Individuals who engage in high-risk activities such as using intravenous drugs, having multiple sexual partners, or getting tattoos or piercings from unlicensed facilities may be deferred from donating blood. This is to reduce the risk of transmitting infectious diseases through blood transfusions.
