A kidney transplant can be an important treatment option for people with advanced or end-stage kidney disease, but not everyone with kidney failure is automatically eligible for transplantation. Before a transplant can be considered, a specialist team needs to determine whether the person is healthy enough to undergo major surgery, whether transplantation is likely to provide meaningful benefit, and whether they can safely manage the lifelong treatment that follows.

Eligibility is therefore not based on age, dialysis status, or kidney function alone. A person's heart and lung health, infections, cancer history, other medical conditions, nutritional and physical condition, immune status, and ability to take anti-rejection medicines are among the factors that may be assessed.

Who Is Generally Considered for a Kidney Transplant?
In general, kidney transplantation is considered for people with advanced chronic kidney disease who are expected to progress to kidney failure or who already have kidney failure and need kidney replacement therapy.
Importantly, transplant evaluation does not always have to wait until dialysis begins. People whose kidney function is progressively declining may be assessed before dialysis is required, which can allow time for medical optimisation and donor evaluation. The central question is not simply “Does this person have kidney failure?” It is: “Is transplantation an appropriate and sufficiently safe treatment for this individual?”
There Is No Single Age Cutoff
Age by itself does not determine whether someone can receive a kidney transplant. Older adults may be considered for transplantation when their overall health and functional status suggest that they can benefit from the procedure.
At the same time, younger age does not automatically make someone suitable if serious medical problems create substantial surgical or post-transplant risks. The transplant team therefore looks beyond chronological age and considers the person's overall health, physical condition, other illnesses, and expected benefit from transplantation.

Does Being on Dialysis Make Someone Eligible?
Being on dialysis does not automatically make someone eligible, but it also does not prevent transplantation. Many kidney transplant recipients have undergone haemodialysis or peritoneal dialysis before receiving their transplant.
Others may receive a preemptive kidney transplant before dialysis begins. The important factor is whether the patient meets the medical and practical requirements for transplantation, rather than whether dialysis has already started.
What Does the Transplant Team Look At?
Kidney transplant evaluation is comprehensive because the operation and the treatment afterward affect several aspects of a person's health. The assessment commonly considers the following areas.

Overall Physical Health
The patient needs to be able to cope with major surgery and the recovery period. Doctors assess general health, physical condition, nutritional status, and the presence of other illnesses that could significantly increase surgical risk.
Heart and Blood Vessel Health
Cardiovascular health is an important part of transplant assessment because major surgery places additional demands on the heart and circulation.
Depending on the patient's age, symptoms, medical history, and risk factors, evaluation may include an ECG, echocardiogram, stress testing, or other cardiovascular investigations.
Infections
Active or significant infections may need to be treated before transplantation. This is particularly important because anti-rejection medicines suppress the immune system after transplant and can increase susceptibility to infections.
Screening may include testing for infections such as hepatitis B, hepatitis C, HIV, and other infections according to the patient's circumstances and local transplant protocols.
Cancer History and Cancer Screening
A current or previous cancer does not automatically mean that transplantation is impossible. However, the transplant team needs to assess the type of cancer, how it was treated, how long the patient has been free of disease, and the risk of recurrence. Age- and risk-appropriate cancer screening is also generally part of transplant evaluation.
Other Medical Conditions
Conditions affecting the lungs, liver, blood vessels, nervous system, gastrointestinal system, bones, or other organs may also be considered.
Having another medical condition does not necessarily rule out transplantation. The question is whether it can be safely managed and whether the overall benefits of transplantation are expected to outweigh the risks.
What About Blood Group and Tissue Matching?
Compatibility is an important part of finding a suitable donor, but it is separate from determining whether a patient is medically eligible for transplantation.
Blood-group testing, tissue typing, and antibody testing help the transplant team understand how compatible a potential donor kidney may be with the recipient.
A person with a difficult antibody profile may have fewer compatible donor options, but this does not necessarily mean that transplantation is impossible. Depending on the circumstances, different donor or matching pathways may be considered.
Does Body Weight Affect Kidney Transplant Eligibility?
Body weight can be considered during transplant assessment because obesity may increase the risks associated with surgery and can affect recovery and long-term health. However, body weight should not be treated as a simple universal pass-or-fail criterion.
The transplant team may consider the person's overall health, distribution of body weight, physical function, cardiovascular risk, nutritional status, and whether weight-related risks can be improved before surgery. For some patients, improving fitness or reducing weight before transplantation may make surgery safer.
Can Someone With Diabetes Receive a Kidney Transplant?
Yes. Diabetes is one of the important causes of kidney failure, and people with diabetes may be considered for kidney transplantation. The transplant team will assess how well diabetes is controlled and whether it has affected other organs, particularly the heart and blood vessels.
In selected patients with diabetes and kidney failure, combined kidney-pancreas transplantation may also be considered. The presence of diabetes alone does not automatically exclude someone from kidney transplantation.

What About Heart Disease?
Heart disease requires careful assessment because transplantation is major surgery. Significant cardiovascular disease may increase the risk of complications, but having heart disease does not automatically mean that a transplant cannot be performed.
Depending on the condition, doctors may recommend additional cardiac testing or treatment before deciding whether transplantation is appropriate.
The goal is to understand whether the cardiovascular condition can be safely managed and whether the expected benefit of transplantation justifies the surgical risk.
Can Someone With a Previous Cancer Have a Kidney Transplant?
Sometimes, yes. A history of cancer requires individual assessment rather than an automatic exclusion. The transplant team may review the type and stage of the cancer, previous treatment, time since treatment, current evidence of disease, and the estimated risk of recurrence. Because anti-rejection medicines affect the immune system, the potential effect of immunosuppression on cancer recurrence is an important part of the decision.
What Tests Are Done to Determine Eligibility?
There is no single test that determines transplant eligibility. Instead, several investigations are combined to create an overall picture of the patient's health. Depending on the individual, evaluation may include:
- Blood and urine tests
- Blood-group and tissue typing
- Antibody testing
- Infection screening
- Heart investigations
- Lung or chest assessment
- Cancer screening
- Imaging of blood vessels and other relevant structures
- Assessment of nutritional and physical health
- Psychological or psychosocial assessment when appropriate
The Bottom Line
There is no single age, eGFR level, medical condition, or dialysis status that automatically determines whether someone is eligible for a kidney transplant.
People with advanced or end-stage kidney disease should be considered for transplantation when appropriate, but the final decision depends on a comprehensive assessment of their overall health, surgical risk, expected benefit, donor compatibility, and ability to manage lifelong post-transplant care.
Conditions such as diabetes, heart disease, obesity, previous cancer, or tobacco use do not necessarily rule out transplantation. They may instead mean that additional evaluation, treatment, or preparation is needed before surgery.
The purpose of a transplant evaluation is therefore not simply to decide whether a patient is “eligible” or “not eligible.” It is to understand the individual's risks, address problems that can be improved, and determine whether transplantation is a safe and appropriate treatment for that person.
