Interleukin 2, Serum
Use
The test is used to measure the concentration of Interleukin 2 (IL2) in serum, which is helpful in understanding the pathophysiology of immune, infectious, or inflammatory disorders. It may also be useful for research purposes. The level of cytokines such as IL2 can vary diurnally, hence for consistent longitudinal studies, it's imperative to measure cytokine levels at the same time each day.
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. Separate specimens must be submitted when multiple tests are ordered.
Limitations
The test's performance characteristics were determined by ARUP Laboratories. The measurement of cytokine levels such as IL2 may be affected by the diurnal variation, and therefore, consistency in sample collection timing is crucial. There are specific rejection criteria for specimens if they are contaminated or heat-inactivated.
