What is the difference between therapeutic phlebotomy and blood donation?
Therapeutic phlebotomy is a medical treatment for conditions like hemochromatosis and polycythemia vera. Blood donation is voluntary and the blood is used for transfusion. In some cases, blood from phlebotomy can be used for transfusion too.
Therapeutic phlebotomy and blood donation both involve removing blood, but their purpose is very different.
What is therapeutic phlebotomy?
A medical procedure used to treat conditions where the body has too much of something in the blood:
- Hereditary hemochromatosis: excess iron that builds up in organs such as the liver and heart
- Polycythemia vera: the bone marrow makes too many red blood cells
- Porphyria cutanea tarda: buildup of porphyrins
Here, regular removal of blood is the treatment itself.
Differences from voluntary donation
| Aspect | Therapeutic phlebotomy | Voluntary donation |
|---|---|---|
| Purpose | Treat the patient's own condition | Help other patients |
| Reason | Medical prescription | Voluntary and altruistic |
| Frequency | Set by your doctor | Limited by donation rules |
| What happens to the blood | May be discarded or used | Used for transfusion |
Can phlebotomy blood be used?
In the US, blood from people with hereditary hemochromatosis can be used for transfusion if they meet donor eligibility rules and the blood is properly labeled. Many blood centers accept these donors, but it varies by center.
If you need therapeutic phlebotomy, ask your doctor and your local blood center what applies to you.
This information is general and does not replace advice from a health professional. Your eligibility is always decided at the donor screening on the day of donation. Rules change, so confirm with the American Red Cross or the blood center where you plan to donate.
