Interleukin-12 (IL-12p70) Plasma
Cytokines have emerged as molecules of importance in the regulation of many immunologic processes in the cell. The ability to accurately measure quantitative and qualitative differences in cytokine production is becoming increasingly important to the understanding of normal and pathological processes.
Multiplex array format with Meso Scale Discovery (MSD®) Sector Imager 2400. MSD Cytokine assays measure from one to ten cytokines in a 96 well MULTI-SPOT plate. The assay employs a sandwich immunoassay format. MSD technology uses electrochemiluminescence detection; a CCD camera allows for the quantification of light emitted from each spot in each well. MSD software generates a standard curve to determine sample cytokine concentrations. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.

The result is reported in pg/mL. The assay range is approximately 1.2 to 2448. The reference range for a healthy population is less than 1.2. However it should be noted that these ranges are obtained from a limited population of apparently healthy adults and are not diagnostic thresholds.
Specimens are approved for testing in New York only when indicated in the Specimen Information field above.
