Why This Test Matters

Cyclosporine is prescribed for conditions like organ transplants, autoimmune diseases, or severe allergies. Keeping levels in the right range helps prevent rejection or overactive immune responses.

Common Causes of Abnormal Results

Changes in dose, liver/kidney function, or illness can affect levels. Your provider will review results with you and adjust your treatment if needed.
