Interleukin 2 Receptor, Soluble, CSF
Also known as: IL2R CSF
Use
The Interleukin 2 Receptor, Soluble, CSF test is primarily used for research purposes to support the understanding of the pathogenesis of immune, infectious, allergic, or inflammatory disorders. It provides critical insights into the immune system's response mechanisms and can aid in the study of disease pathophysiology. The results can have implications for understanding various disorders, though it is not intended for direct diagnostic purposes.
Special Instructions
It is important to note that cytokine levels can exhibit diurnal variation. For accurate longitudinal comparison, cytokine levels should be determined at the same time of day for each test. This can help account for natural fluctuations and improve the reliability of comparisons over time.
Limitations
This test has not been cleared or approved by the US Food and Drug Administration, meaning it should primarily be used for clinical purposes in a CLIA-certified laboratory. The test's performance characteristics were determined by ARUP Laboratories, highlighting that it is a laboratory-developed test (LDT). As a result, the interpretations derived from this test should be considered within the context of research rather than clinical diagnosis.
