Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Cytokines are important mediators of cell-to-cell communication within the innate and adaptive immune systems. The expression of most cytokines is highly regulated and generally occurs in response to foreign or self-antigenic stimulation. The functions of cytokines are extremely varied, with many cytokines also displaying pleiotropic effects, depending on their cellular target. Some cytokines, such as tumor necrosis factor (TNF), interleukin (IL)-1 beta, IL-6, interferon (IFN)-alpha and beta, IL-10, and IL-18 are particularly important in the innate immune response. For example, TNF, IL-1 beta, and IL-6 induce expression of acute phase proteins in the liver. TNF and IL-1 beta also lead to endothelial activation and are critical regulators of the hypothalamus, which can result in elevated body temperature. IL-6, in comparison, is a bridge to the adaptive immune response, by acting on B cells to induce proliferation. In contrast, IFN-alpha and IFN-beta (members of the type I IFN family) are key components of the innate immune response to viral infections. IFN-gamma, which is a type II IFN, has roles in both the innate and adaptive immune responses, including macrophage activation, induction of B-cell isotype switching, and T helper type 1 cell differentiation. Other cytokines, such as monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein-1alpha (MIP-1alpha), are categorized as chemokines because they function primarily to attract leukocytes to the site of inflammation. Further, some cytokines act on hematopoietic stem cells to induce differentiation of various leukocytes. For example, granulocyte-monocyte colony stimulating factor (GM-CSF) induces myeloid progenitor cells to differentiate into neutrophils and monocytes. Lastly, for some cytokines, soluble forms of the receptor can be found in the peripheral circulation. The IL-2 soluble receptor is produced from proteolytic cleavage of the membrane-bound receptor, which occurs during T-cell activation. As a group, cytokines and their receptors represent a highly complex and critical regulator of a normal immune response.

Interpretation
Provides information to assist in interpretation of the test results

Elevated cytokine concentrations could be consistent with the presence of infection or other inflammatory process.

Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Results from cytokine testing should not be used to establish or exclude a specific diagnosis.

 

Cytokine testing should only be used in conjunction with clinical information and other laboratory testing as part of a patient’s overall assessment.

 

Normal concentrations of cytokines do not exclude the possibility of infection or other inflammatory condition.

 

Cytokine concentrations could be affected by immunomodulatory agents.

Method Description
Describes how the test is performed and provides a method-specific reference

Analyte-specific antibodies are pre-coated onto color-coded magnetic microparticles. Samples are diluted 1:2 in a mixing plate and then standards, samples, and microparticles are pipetted into wells and the immobilized antibodies capture the analytes of interest. Unbound substances are washed away while the magnetic microparticles are immobilized. Next, a biotinylated analyte specific antibody cocktail is added to each well. Following a wash to remove any unbound biotinylated antibody, streptavidin-phycoerythrin conjugate (Streptavidin-PE), is added to each well. After removal of unbound Streptavidin-PE and resuspension of the microparticles in buffer, the plate is analyzed using a Luminex FLEXMAP 3D analyzer. A charged-coupled device (CCD) camera captures an image of each well and data reduction is performed using the XPONENT software.(Unpublished Mayo method)
