Interleukin 2, Plasma
Also known as: IL2 PLA
Use
The test is primarily used for research and to support attempts to understand the pathogenesis of immune, infectious, allergic, or inflammatory disorders. Results can provide insight into the pathophysiology of such conditions and may aid in research efforts by offering quantitative data on cytokine levels.
Special Instructions
Cytokine levels may demonstrate diurnal variation. For longitudinal comparison, it is recommended that cytokine levels be determined at the same time of day. This test is New York state approved and categorized as a Laboratory Developed Test (LDT).
Limitations
This test was developed and its performance characteristics determined by ARUP Laboratories. It is performed in a CLIA certified laboratory but is not FDA cleared or approved. The test's results are for investigational use to understand disease mechanisms and are not intended as primary diagnostic evidence. There is a note that refrigerated specimens and contaminated or heat-inactivated specimens are not accepted.
