Age vs. Health: A Changing Perspective
For many years, some transplant centers and individuals held the belief that there was a definitive upper age limit for donating a kidney. However, modern medical advancements and an increased understanding of physiology have shifted the focus away from chronological age and toward a person's overall health. This changing perspective recognizes that a healthy 70-year-old may be a better candidate for living donation than an unhealthy 40-year-old.
For example, Sander Orent successfully donated a kidney to his wife at age 72, after finding a transplant center that evaluated his health instead of his birthdate. Likewise, in 2024, there was a 14.2% increase in living donors over the age of 65 compared to the previous year, with more centers focusing on case-by-case health assessments. This trend has been a beacon of hope for many patients awaiting a transplant, particularly older recipients, who often benefit from a living donor kidney.
Why Health Trumps Age
The reason for this paradigm shift is rooted in medical evidence. A comprehensive evaluation of a prospective donor’s health reveals far more about their suitability than a single number. The transplant team assesses the health of the heart, lungs, and remaining kidney to ensure the donor can safely undergo surgery and live a long, healthy life with one kidney. The physiological age of the organs and the absence of comorbidities are the most important criteria, making it clear why health is the key determinant.
The Comprehensive Donor Evaluation Process
Becoming a living kidney donor, regardless of age, involves a multi-stage, confidential evaluation to ensure the safety of the donor. For older candidates, this process is particularly thorough, with specific age-appropriate tests and consultations.
The Evaluation Stages
- Initial Health Screening: A review of your medical history, current health status, and a discussion of your motivations for donating.
- Medical Tests: An extensive battery of blood and urine tests, along with imaging scans like a CT scan, to assess kidney function, structure, and overall organ health.
- Cardiac Screening: For donors over 50, a cardiac stress test may be performed to ensure heart health.
- Psychosocial Assessment: A meeting with a social worker or psychologist ensures the donor is mentally and emotionally prepared and acting voluntarily, without pressure or financial coercion.
- Independent Living Donor Advocate: An independent advocate works solely for the donor, ensuring their interests and rights are protected throughout the entire process.
Factors That Influence Eligibility
While age is not a hard limit, certain health conditions can disqualify a potential donor. For older individuals, some of these risks are more prevalent, which is why a thorough evaluation is essential. Key disqualifying factors include:
- Uncontrolled Chronic Conditions: Significant or poorly controlled conditions like hypertension (high blood pressure) or diabetes.
- History of Certain Cancers: Some types of cancer, particularly metastatic cancer, are automatic disqualifiers. However, some cancers successfully treated years ago may be acceptable.
- Major Cardiovascular Issues: A history of heart disease, stroke, or severe lung disease.
- Morbid Obesity: Excess weight increases surgical risk and long-term health complications.
- Bleeding or Clotting Disorders: These can increase surgical risk.
The Role of the Transplant Center and Finding a Match
Each transplant center has its own policies and may set its own internal guidelines regarding the upper age limit for living donors. Some centers are more conservative, while others are more flexible, focusing instead on the individual's physiological health. If you are an older, healthy adult interested in donating, and one center says no, don't be discouraged. You can and should seek evaluation at another transplant center that may have different criteria.
Living Donation vs. Deceased Donation
It is important to distinguish between living and deceased organ donation. The rules for deceased donation are different, and there is no upper age limit for registering as a deceased organ donor. In fact, people well into their 90s have successfully donated organs or tissue after death. A medical team at the time of death determines the suitability of organs for transplant.
Comparing Outcomes from Older Donors
Research has shown that kidneys from older living donors can have excellent outcomes, often comparable to younger deceased donors. This is particularly beneficial for older recipients, where receiving a living donor kidney is often preferable to waiting for a deceased donor organ. The risk for the donor, when appropriately selected, remains very low.
| Donor Type | Recipient Age (Example) | Key Outcome | Notes |
|---|---|---|---|
| Living Donor (Age 70+) | Matched Recipients (Age 50-59+) | Similar long-term survival to deceased donor kidneys | Requires careful donor selection and evaluation. |
| Living Donor (Age 50-59) | Matched Recipients | Graft loss significantly lower than older donors | Still better than deceased donor options. |
| Deceased Donor (Age 50-59) | Matched Recipients (Age 50-59+) | Graft survival lower than younger living donors | Used as a benchmark for comparison. |
| Extended Criteria Donor | Elderly Recipients | Significant survival benefit vs. staying on dialysis | Addresses the organ shortage for specific populations. |
Next Steps for Potential Older Donors
If you are an older adult considering kidney donation, the first and most crucial step is to begin the conversation. Contact a transplant center and start the evaluation process. Here's how to prepare:
- Maintain Your Health: Continue to manage any pre-existing conditions, maintain a healthy diet, and engage in regular exercise.
- Gather Your Medical History: Organize your medical records to provide the most accurate information during the screening process.
- Prepare for the Process: Understand that the evaluation is comprehensive and involves multiple appointments. Be patient and transparent with the transplant team.
The message for healthy older adults is clear: your age does not automatically disqualify you. With a strong health profile, you can still give the incredible gift of life.

Conclusion
While the question "Is there a cutoff age for kidney donation?" is common, the reality is that the decision is far more nuanced than a simple number. For living kidney donation, eligibility is not bound by chronological age but by a meticulous assessment of your physiological health. As medical science evolves and more transplant centers adopt case-by-case evaluation, an increasing number of healthy older adults are proving that generosity knows no age limit. By focusing on your health and working with a dedicated transplant team, you can leave a lasting legacy and save a life, no matter your age.
