Can You Give Blood with Lyme Disease?

Lyme disease has become a significant concern worldwide, and people are often curious if someone with Lyme disease can donate blood. Lyme disease is a tick-borne infection caused by the bacterium Borrelia burgdorferi. The bacterium can cause symptoms ranging from mild to severe, such as fever, fatigue, joint pain, and if left untreated, paralysis.

Donating blood can save lives, but it is necessary to ensure that the donation process is safe both for the recipient and the donor. In this post, we will answer the question- Can you give blood with Lyme disease?.

Understanding Lyme Disease

Lyme disease is transmitted through tick bites, and it is a bacterial infection that produces various symptoms. If left untreated, Lyme disease can negatively affect the heart, joints, and nervous system. Manifestations of Lyme disease can range from mild to severe, and some people do not have any symptoms.

Borrelia burgdorferi, the bacterium that causes Lyme disease, can enter the bloodstream and remain active in the blood.

Therefore, it is essential to consider the potential risks associated with donating blood in this case.

Can You Donate Blood If You Have Lyme Disease?

Technically, there is no specific law or regulation barring people with Lyme disease from donating blood. However, the American Red Cross has barred people with a history of Lyme disease from donating blood in the past.

If you have been diagnosed with Lyme disease, the blood bank may refuse to accept your blood, considering the potential risks to recipients. Some studies suggest that Lyme disease can spread through blood transfusion, although the incidence of transmission through blood donations is rare.

Therefore, to be on the safe side, people should avoid donating blood if they have a current or past diagnosis of Lyme disease.

What If You Have Been Treated for Lyme Disease?

If you have a history of Lyme disease, and you have been successfully treated for the bacterium, you may be eligible to donate your blood if you meet certain conditions.

According to the American Red Cross, people with a history of Lyme disease are eligible to donate blood if they received a single course of antibiotics and have no leftover symptoms after completing the treatment. Additionally, you must wait for 14 days after the last dosage of antibiotics before donating blood.

What If You Have Been Recently Bitten by a Tick?

If you have recently been bitten by a tick and you suspect that you have contracted Lyme disease or have symptoms, you should avoid donating blood. Lyme disease can be easily diagnosed through a blood test. You should wait for at least six weeks after the onset of the infection and the completion of your treatment before donating blood.

Risks of Blood Transfusion

People who receive blood transfusions are vulnerable to many risks, including viral infections, bacterial infections, allergic reactions, and transmission of diseases such as Chagas disease, HIV, and hepatitis B and C.

Lyme disease is not typically life-threatening, but it can cause severe complications if left untreated. Therefore, when transfused, the blood can transfer the infection to the recipient, which can be life-threatening in rare cases.


Donating blood is a noble cause that can save lives. However, if you have Lyme disease, you should not donate your blood. Although blood transfusion-associated Lyme cases are rare, the risk still exists. If you have been diagnosed with Lyme disease in the past or have suspected symptoms, it is crucial that you disclose this to the blood bank, and avoid donating blood.
