Interleukin 13, Serum
Also known as: IL13 DO
Use
The Interleukin 13 test measures serum levels of IL-13, which is primarily used for research and to support understanding of the pathogenesis of immune, infectious, allergic, or inflammatory disorders. It helps in examining the pathophysiology of related disorders and may aid research purposes in immune response assessments.
Special Instructions
Cytokine levels may demonstrate diurnal variation; therefore, for longitudinal comparisons, it is recommended to determine cytokine levels at the same time of day.
Limitations
The test is a Laboratory Developed Test (LDT) and has not been cleared or approved by the US Food and Drug Administration. This limitation means the test performance is determined by ARUP Laboratories under CLIA certification, but regulatory approval has not been secured, which might limit its recognition outside specific clinical or research contexts. Sample stability and inadequate sample handling or contamination might also limit the reliability of results.
