Most people think a kidney transplant comes after dialysis. That order is backward for many patients. The best time to start the transplant process is before you ever need dialysis.
Late referral is one of the most common and most costly mistakes in kidney care. Waiting time, testing and donor searches all take months to years. Patients who start early have more choices, including a transplant that skips dialysis entirely.
Why Timing Matters So Much
A kidney transplant is the best treatment for kidney failure for most eligible patients. On average, recipients live longer and feel better than similar patients who stay on dialysis. Outcomes are best when the transplant happens early, before years on dialysis strain the heart and blood vessels.
A transplant done before dialysis starts is called a preemptive transplant. It is linked to better long-term kidney survival than a transplant after dialysis. A living donor transplant offers the longest-lasting results of all.
The eGFR Numbers That Drive Referral
| eGFR (mL/min/1.73 m²) | CKD Stage | What Should Happen |
| 30 to 44 | 3b | Discuss future options; start education if kidney function is falling fast |
| Under 30 | 4 | Referral to a transplant center is recommended if kidney disease is progressing |
| 20 or below | 4 to 5 | Once listed, deceased donor waiting time begins to count |
| Under 15 or on dialysis | 5 | Referral is overdue if not already done; waiting time counts from the dialysis start date |
International transplant guidelines advise referral at least 6 to 12 months before dialysis is expected. National allocation rules let waiting time start when you are registered and your eGFR is 20 or lower. If you only get referred after dialysis begins, waiting time is backdated to your first dialysis treatment, but you still lose the chance at a preemptive transplant.

Race-Neutral eGFR and Waiting Time Credit
Older eGFR formulas included a race adjustment that made kidney function look better in Black patients. That delayed when many could start earning waiting time. National rules now require race-neutral eGFR, and transplant centers have been adjusting waiting time for Black candidates who were affected. If you are on a list, ask your center whether your record was reviewed.
Who Should Be Referred?
The short answer: anyone with progressive CKD stage 4 or 5 who might be a candidate. Let the transplant center decide eligibility. Many patients rule themselves out for reasons that no longer apply.
Common Myths That Delay Referral
- “I am too old.” There is no strict age cutoff. Many centers transplant healthy patients in their 70s.
- “I have diabetes.” Diabetes is the leading cause of kidney failure, and many people with diabetes receive transplants.
- “I do not have a donor.” You can join the deceased donor list while looking for a living donor.
- “I cannot afford it.” Medicare covers kidney transplant for most people with kidney failure, and centers have financial counselors.
Conditions That May Delay or Prevent Transplant
- Active cancer or a recent cancer that needs a waiting period.
- Active infection that is not controlled.
- Severe heart or lung disease that makes surgery unsafe.
- Active substance use or a history of not taking medicines.
- Very high body weight at some centers, often a BMI over 35 to 40.
Many of these are fixable. Weight loss, cardiac treatment or finishing cancer surveillance can turn a “not yet” into a “yes.”
What Happens After Referral: The Transplant Evaluation
Referral starts a detailed evaluation at a transplant center. Expect several visits and a long list of tests. Our article on preparing for a kidney transplant covers the practical side.
Medical Testing
- Blood type and tissue typing (HLA): used to match you with donors.
- Antibody screening (cPRA): shows how sensitized you are from past pregnancies, transfusions or transplants.
- Heart testing: EKG, echocardiogram and often a stress test.
- Cancer screening: colonoscopy, mammogram, Pap test or PSA based on age.
- Infection screening: hepatitis B and C, HIV, tuberculosis and others.
- Dental exam: to clear any source of infection.
Social, Emotional and Financial Review
A social worker reviews your support system, transportation and ability to take anti-rejection medicines every day. A financial counselor reviews coverage. Kidney failure is stressful. Our article on mental health and emotional support for kidney patients offers practical help.
How Long Does It Take?
| Phase | Typical Time | What You Can Do |
| Referral to first center visit | Weeks to a few months | Gather records, complete forms quickly |
| Evaluation testing | 2 to 6 months | Schedule tests promptly, keep a checklist |
| Listing decision | After committee review | Address any “not yet” items |
| Deceased donor wait | Often 3 to 5 years or more, depending on blood type, antibodies and region | Keep contact info current, stay healthy and active |
| Living donor transplant | Often months once a donor is approved | Share your story; ask about paired exchange |
Living Donation Shortens the Wait
A living donor kidney usually lasts longer than a deceased donor kidney, and surgery can be scheduled. If a willing donor is not a match, paired exchange programs can swap donors between pairs. Learn what donors go through in our guide to kidney transplant donor care.
Local Factors for Patients in Southern Oklahoma and North Texas
| Local Factor | Impact | Practical Strategy |
| Transplant centers are 1.5 to 2.5 hours away in Oklahoma City, Tulsa or Dallas-Fort Worth | Travel burden for evaluation and follow-up | Cluster tests on one trip; complete local testing through your nephrologist |
| Oklahoma and North Texas fall under different organ procurement areas | Wait times can differ by center | Ask about evaluation at more than one center |
| Rural patients may lack reliable transportation | Missed evaluation steps | Social worker help with travel programs and Medicaid transport |
| Native American patients may have tribal health benefits | Extra support for medicines and travel | Coordinate tribal health, Medicare and transplant center financial teams |
The Value of Early Referral
| Factor | Early Referral (eGFR under 30) | Late Referral (After Dialysis Starts) |
| Chance of preemptive transplant | Possible | Lost |
| Waiting time | Starts at eGFR 20 once listed | Backdated to dialysis start only |
| Living donor search | Months to organize | Rushed or delayed |
| Health at surgery | Usually better | Strained by time on dialysis |
| Cost to the health system | Lower over time after the first year | Dialysis costs roughly $100,000 a year before transplant |
How Your Nephrologist Fits Into the Transplant Process
Your nephrologist makes the referral, sends records, completes local tests and keeps your kidneys as healthy as possible while you wait. After transplant, the nephrologist often shares care with the transplant center for life.
- Before transplant: slowing CKD, managing anemia, bone health and blood pressure, and planning dialysis access if needed.
- During evaluation: coordinating tests close to home.
- After transplant: drug level checks, infection prevention and early detection of rejection. Learn the warning signs in our guide to kidney transplant rejection.

Frequently Asked Questions
Can I get referred if I am not on dialysis yet?
Yes, and that is the ideal time. Referral at eGFR under 30 with falling function gives the best chance at a preemptive transplant.
Does Medicare pay for a kidney transplant?
Medicare covers kidney transplant for most people with kidney failure who qualify. Coverage based only on kidney failure ends 36 months after transplant, but a separate Medicare benefit can help pay for anti-rejection drugs after that.
Can I be listed at more than one transplant center?
Often, yes. Multiple listing is allowed, though each center runs its own evaluation and may have its own costs and travel needs.
What if I am told I am not a candidate?
Ask why, and ask what would change the answer. Many reasons are temporary. You can also seek a second opinion at another center.
Is conservative care an option instead?
Yes, for some patients, especially older adults with many health problems. Our article on stage 5 CKD without dialysis explains that path.
Ask About Transplant Referral at Your Next Visit
If your eGFR is under 30, or falling fast toward that number, ask your doctor about transplant referral now. The earlier the conversation starts, the more options you keep.
Southern Oklahoma Kidney Center provides kidney transplant patient care before and after surgery, with clinics in Ada, Gainesville and our Ardmore kidney clinic. Call (580) 223-8614 or schedule a transplant planning visit.
