Kidney Transplant Evaluation: What Tests Are Done Before Approval

What tests are done before a kidney transplant evaluation?

Before a kidney transplant is approved, both the recipient and the potential donor undergo a structured series of medical tests. These include blood typing, HLA tissue matching, renal function tests, cardiac assessment, imaging, and infectious disease screening. The evaluation confirms medical suitability and reduces the risk of organ rejection.

Lilavati International in Mumbai offers comprehensive nephrology and transplant evaluation services at its quaternary-care facility in Bandra West, supported by round-the-clock access to CT, MRI, ultrasound, and a full diagnostic laboratory. The hospital holds JCI and NABH accreditations.

Who is eligible for a kidney transplant?

Eligibility for a kidney transplant is determined during the evaluation process. Candidates are typically patients with end-stage renal disease (ESRD) or chronic kidney disease (CKD) at stage 5, where the kidneys can no longer sustain life without dialysis or transplantation.

Factors assessed during eligibility screening include:

• Severity and cause of kidney failure
• Overall cardiovascular health
• Absence of active infection or untreated malignancy
• Absence of conditions that would make surgery unsafe
• Psychological readiness and ability to adhere to post-transplant medication
• Body weight and nutritional status

Certain conditions may disqualify a patient from receiving a transplant, including active cancer, severe heart or lung disease that cannot be corrected, active substance dependence, or an inability to comply with immunosuppressive therapy. Each case is reviewed individually by the transplant team.

What is the complete test list for a kidney transplant evaluation?

The pre-transplant evaluation covers multiple organ systems to ensure the patient can safely undergo surgery and tolerate lifelong immunosuppression. Tests are conducted for both the recipient and the living donor (if applicable).

The HLA test evaluates six key markers (HLA-A, HLA-B, HLA-C, HLA-DR, HLA-DQ, HLA-DP) to assess compatibility between donor and recipient. The PRA test measures the level of antibodies in the recipient's blood that could attack donor tissue — a high PRA score indicates a higher risk of rejection.

What tests does a living kidney donor need to undergo?

Living donors — whether related or unrelated to the recipient — must pass a separate, rigorous evaluation to confirm that donation is safe for them and that the donated kidney is suitable for the recipient.

• Blood and tissue typing: ABO compatibility and HLA matching with the recipient
• Renal function tests: GFR measurement, urine analysis, 24-hour urine collection
• Imaging: CT angiography or MRI to assess kidney anatomy and blood supply
• Cardiovascular assessment: ECG, blood pressure monitoring, echocardiogram
• Infectious disease screening: HIV, Hepatitis B and C, CMV, tuberculosis
• Metabolic tests: Blood glucose, lipid profile, liver function
• Psychological evaluation: Confirming voluntary, informed consent and mental readiness

In India, a living donor can give a kidney to a non-family member, but this requires approval from an Authorisation Committee under the Transplantation of Human Organs and Tissues Act (THOTA). The committee reviews the relationship, motivation, and absence of commercial exchange before granting clearance.

How does the kidney transplant evaluation process work, and how long does it take?

The kidney transplant evaluation is a multi-step process coordinated by a transplant team that typically includes a nephrologist, transplant surgeon, cardiologist, social worker, and transplant coordinator.

1. Initial referral and consultation: The nephrologist reviews the patient's kidney disease history and determines whether transplant evaluation is appropriate.
2. Medical testing: Blood tests, imaging, cardiac workup, and infectious disease screening are completed — usually over several clinic visits or a short inpatient stay.
3. Specialist reviews: Results are reviewed by relevant specialists (cardiologist, urologist, etc.) to identify and address any conditions that could affect surgical safety.
4. Transplant committee review: The full transplant team meets to discuss the case and determine eligibility.
5. Listing or donor matching: If approved, the patient is listed for a deceased-donor kidney or proceeds with living-donor matching.

The evaluation process typically takes a few weeks to several months, depending on the complexity of the patient's medical history, the availability of specialist appointments, and whether additional investigations are required. Patients with a living donor may move through the process more quickly than those awaiting a deceased-donor organ.

When should a patient with kidney disease consult a nephrologist about transplant evaluation?

Early referral to a nephrologist for transplant evaluation is associated with better outcomes. Do not wait until dialysis is the only option. Consult a nephrologist about transplant evaluation if:

• Your GFR (glomerular filtration rate) falls below 20 mL/min/1.73 m² — this is stage 4–5 CKD
• Your nephrologist has indicated that kidney failure is likely within 12 months
• You have been on dialysis (haemodialysis or peritoneal dialysis) and wish to explore transplant as an alternative
• A family member has offered to be a living donor and you want to understand compatibility
• You have been told you may be a candidate for pre-emptive transplantation (before dialysis begins)

Pre-emptive transplantation — receiving a kidney before starting dialysis — is associated with improved graft survival and quality of life. Early evaluation gives the transplant team time to address any medical issues that might otherwise delay or prevent surgery.
