What is this test?
This term describes laboratory testing for a kidney transplant recipient rather than one specific test. The blood or urine tests ordered may assess kidney function, blood counts, medication effects, infection risk, or signs of rejection.
Why might I need this test?
Regular testing helps your transplant team follow the health of the transplanted kidney and identify medication side effects or other complications. The specific tests and frequency depend on your transplant program and medical history.
How is the test performed?
A healthcare professional usually collects a blood sample, and sometimes a urine sample, for laboratory analysis. Some results require specialized instruments or testing at a reference laboratory.
How do I prepare for the test?
Follow the instructions provided by your transplant team. If you are taking immunosuppressant medicines, do not change or skip a dose unless your clinician tells you to, and tell the laboratory about medicines and supplements you use.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal results may reflect reduced kidney graft function, rejection, infection, medication toxicity, or another health problem. The meaning depends on which test is abnormal and your overall transplant history. Results should be interpreted by your transplant team in the context of other clinical findings.
