Interferon-gamma (IFN-y) Serum
Use
The Interferon-gamma (IFN-y) Serum test is used to measure levels of IFN-y, a cytokine critical in the immune response, in the serum. This test can be significant in diagnosing and monitoring conditions where IFN-y production is altered. It may be used in the context of autoimmune disorders, infections, or immune dysregulation syndromes where levels of IFN-y provide insights into the underlying immune response.
Special Instructions
The test requires blood to be drawn into a plain red-top tube or serum gel tube, which should then be centrifuged to isolate serum for submission. The sample must be sent frozen in a plastic vial to maintain stability for up to 365 days.
Limitations
The test has not been cleared or approved by the FDA, which may limit the use of results in some clinical settings. Results can be affected by improper specimen handling, including thawing, which leads to rejection. Ensure proper freezing and handling to maintain specimen integrity.
