What is this test?

Kidney transplant recipient status is a clinical history item that records whether you have received at least one kidney transplant at a transplant center. It may be completed from your medical record or confirmed during an intake assessment.

Why might I need this test?

Your care team may review this information before surgery, medication prescribing, laboratory testing, or follow-up care. It helps the team account for your transplant history when evaluating your current kidney health.

How is the test performed?

This is generally a record review or a yes-or-no history question rather than a laboratory analysis. A positive entry is usually linked to documentation of a kidney transplant procedure.

How do I prepare for the test?

No special preparation is usually needed. Bring accurate information about any kidney transplant, including the approximate date and transplant center, if it is available.

Reference range

Adult: 10-40 U/LN/A

Specimen: serum

No special preparation required. Avoid fatty meals before the test if possible.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

A positive result indicates that you have received at least one kidney transplant. It does not by itself show how well the transplanted kidney is working or whether rejection is present; those conditions are assessed using other clinical findings and laboratory tests.

Frequently asked questions

Does a positive result mean my kidney transplant is working?
No. It confirms a history of transplantation, but graft function and possible rejection require separate evaluation.
Will I need a blood test for this?
This item is usually completed by reviewing your medical history or answering a screening question. Blood tests may be ordered separately to assess kidney function.
What if I received a kidney transplant at another hospital?
Tell your care team about the transplant and provide records if available. The history can still be documented even if the original center is no longer involved in your care.
