What This Test Measures

This evaluation includes tests for immune function, organ health, and markers that may indicate compatibility with a donor organ. It may include blood tests for antibodies, kidney function, liver enzymes, and other measures to ensure your body can safely receive a new organ.

Common Blood Tests Included

While the exact tests vary by center, you may have blood drawn for general health checks such as complete blood count (CBC), liver function tests, kidney function tests, and specific antibody panels to assess immune response.

Why It Matters for Transplant

Your immune system must be carefully monitored to avoid rejecting a transplanted organ. This test helps identify risks of organ rejection or complications like infections or graft-versus-host disease.

What to Expect Before the Test

You may need to fast for 8–12 hours before some blood draws, and your doctor will explain any restrictions. Bring your medical records and a list of medications you’re currently taking.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Why might I need this test?
This test is typically ordered if you’re a candidate for organ transplantation, such as a kidney, liver, heart, or lung transplant. It helps ensure your body is healthy enough for the procedure and identifies any risks that could affect transplant success.
What does a high/low result mean?
Results may show whether your immune system is functioning normally, if your organs are healthy, or if you have antibodies that could cause rejection. Your doctor will discuss these findings in detail during your evaluation.
How long will it take to get results?
Results are usually available within 1–3 business days, but timing may vary depending on the lab and tests included. Your doctor will contact you once they are ready for review.
