Understanding the Truth About Organ Donor Eligibility
The decision to become an organ donor is a profoundly generous one, yet many people mistakenly believe that a past or present medical condition automatically disqualifies them. In reality, the criteria for organ donation are more flexible than many assume. The final determination of a person's eligibility is not made until the time of death by a team of medical professionals, who assess the viability of each individual organ. Rather than ruling yourself out, the most important step is to register your intent to donate and let medical experts make the final call.
Absolute vs. Relative Exclusions
Medical conditions can generally be categorized into absolute and relative contraindications for organ donation. Absolute exclusions are conditions that almost always prevent donation due to the high risk of transmitting disease or cancer to a recipient. Relative exclusions are more nuanced and are evaluated on a case-by-case basis. These are conditions that might affect the viability of specific organs but not necessarily the entire donation process.
Absolute Contraindications
These are the rare conditions that make a person ineligible for organ donation under most circumstances to protect the safety of the recipient:
- Active, Systemic Infections: A widespread, uncontrolled infection (sepsis) at the time of death is an absolute contraindication for donating solid organs. This is to prevent the recipient from contracting a life-threatening infection. Localized infections, however, may not prevent the donation of other organs.
- Creutzfeldt-Jakob Disease (CJD): This is a rare, fatal brain disorder that is transmissible and is considered an absolute contraindication for donation.
- Active Metastatic Cancer: Cancer that has spread throughout the body (metastatic cancer) is typically an absolute exclusion. The risk of transmitting malignant cells is considered too high. This is different from a history of successfully treated cancer, which may not be a barrier.
Relative Contraindications and Case-by-Case Assessment
Many other health conditions are not automatic disqualifiers. Instead, they require a careful assessment by transplant specialists. This is because a condition may only affect certain organs, leaving others perfectly healthy for donation. Below are several examples of relative exclusions and common misunderstandings:
- History of Cancer: A history of cancer does not automatically exclude you. The eligibility depends on the type of cancer, when it occurred, and whether it has been successfully treated and in remission. Some non-aggressive cancers, like certain skin cancers, or those treated long ago, may not prevent donation.
- Hepatitis B and C: In the past, having hepatitis B or C was often a barrier. However, with advances in medical treatment, organs from donors with hepatitis can sometimes be transplanted into recipients who also have hepatitis. The final decision is based on a careful analysis of the donor's and recipient's specific conditions.
- HIV-Positive Status: The HIV Organ Policy Equity (HOPE) Act, passed in 2013, allows for the donation of organs from an HIV-positive donor to an HIV-positive recipient under specific research protocols. This has expanded the pool of available organs for individuals living with HIV.
- Diabetes and High Blood Pressure: These are very common conditions and do not automatically disqualify someone from being an organ donor. While a person with long-standing diabetes might have kidney damage, other organs, such as the heart or liver, may be perfectly healthy and suitable for donation.
- Age: There is no specific age limit for organ donation. The health and condition of the organs are far more important than the donor's age. Many successful transplants have used organs from donors in their 70s, 80s, and even 90s.
Living vs. Deceased Donor Criteria
It is important to distinguish between the criteria for living and deceased donors. Living donation (typically a kidney or part of a liver) involves a much more extensive evaluation to ensure the donor remains healthy and safe after the procedure. For living donors, some conditions that might not be a barrier for deceased donation, such as controlled hypertension or diabetes, could be disqualifying factors due to the potential risk to the living donor.
How Donor Eligibility is Determined
When a person registers as an organ donor, it is an expression of intent. It is not a guarantee that donation will occur. At the time of a potential donor's death, an organ procurement organization (OPO) is contacted, and a detailed medical evaluation takes place. This process includes reviewing medical records, performing blood tests, and physically examining the organs. This thorough screening ensures the safety of the potential recipient.
Common Factors in Donor Evaluation
- Medical and social history review
- Blood and tissue typing
- Screening for infectious diseases and certain cancers
- Assessing the health and function of each individual organ
This robust evaluation system ensures that only the safest and most viable organs are used for transplant. It is why you should never disqualify yourself. Registering gives the medical team the opportunity to perform this vital evaluation when the time comes.
Dispelling Myths and Encouraging Registration
The misconception that most people are ineligible can severely limit the donor pool. The truth is that medical science is constantly evolving, and what might have been an absolute exclusion in the past may no longer be one today. For example, advances in anti-viral therapies and HIV-related legislation have changed donation possibilities for people with HIV. The best way to help save lives is to register as a donor and allow the medical professionals to make an informed, case-by-case decision.

A Comparative Look: Deceased vs. Living Donor Criteria
To further illustrate the differences, consider this comparison table outlining the general criteria for deceased and living donors.
| Feature | Deceased Donor (At Time of Death) | Living Donor (During Life) |
|---|---|---|
| HIV-Positive | Can donate to HIV-positive recipient under HOPE Act protocol. | Can donate to HIV-positive recipient under specific protocols. |
| Active Metastatic Cancer | Generally excluded. | Excluded due to risk and complex health factors. |
| Past History of Cancer | Often eligible, depends on type and remission duration. | Eligible if past cancer meets specific remission criteria. |
| Age | No specific age limit; based on organ health. | Must be an adult (typically 18+); age limits vary by transplant center. |
| Diabetes/Hypertension | Might be able to donate some organs, depends on organ health. | Could be excluded, especially if uncontrolled, due to risk to donor. |
| Systemic Infection | Absolute exclusion. | Excluded; must be healthy to proceed. |
| Full Medical History Review | Yes, to assess organ viability. | Yes, extensive medical and psychosocial evaluation. |
Conclusion: The Importance of Individual Assessment
Ultimately, no single health condition, with a few rare exceptions, should prevent you from registering your intent to be an organ donor. The process is a careful and compassionate one, designed to maximize the chances of a successful transplant while ensuring the safety of the recipient. By registering, you allow medical professionals to perform the necessary assessments at the appropriate time, providing hope to those on the waiting list. Your decision to donate can save and transform lives, regardless of your personal health history.
