Determine whether HSV-1 or HSV-2 DNA associated with active viral shedding is detected in the oropharyngeal sample.
Measures Epstein-Barr virus viral-capsid IgG and IgM antibodies to provide information about EBV exposure pattern.
Measures EBV viral-capsid and early-antigen IgG antibodies to add detail to an Epstein-Barr antibody pattern.
Uses an interferon-gamma release assay to identify an immune response consistent with infection by Mycobacterium tuberculosis.
Measures beta-2 microglobulin, a protein associated with immune-cell turnover and kidney filtration that can provide specialized information in selected hematologic, immune and renal evaluations.
Quantifies three major antibody classes to provide a broad view of circulating immunoglobulin levels.
Measures MMP-9, an enzyme involved in extracellular-matrix remodeling and inflammatory signaling.
Measures IL-12p70, an immune cytokine involved in T-cell and natural-killer-cell signaling and cell-mediated immune responses.
Measures interleukin-13, an immune-signaling cytokine involved in type 2 immune responses and inflammatory signaling.
Measures interleukin-8 (IL-8), an inflammatory signaling cytokine involved in immune-cell recruitment and inflammatory activity.
Tests for hepatitis B core antibodies and reflexes according to Labcorp's defined pathway when indicated, providing information about natural HBV exposure.
Measures antibodies against streptolysin O, providing evidence of an immune response following group A streptococcal exposure.
Measures IgM antibodies to the EBV viral capsid antigen, commonly used in evaluating recent Epstein-Barr immune response patterns.
Measures CD4 helper and CD8 suppressor T-cell counts, percentages and their ratio, along with a CBC differential, to provide a detailed view of T-cell distribution.
Measures complement C4a, a split product generated during complement activation, for specialized immune/inflammatory evaluation.
Measures TGF-β1, an immune-signaling cytokine involved in regulation of inflammation, tissue repair and immune activity.
Measures TNF-alpha, a major inflammatory cytokine involved in immune signaling and inflammatory responses.
Measures interleukin-10 (IL-10), an immune-regulatory cytokine involved in moderating inflammatory responses.
Measures interleukin-4 (IL-4), an immune-signaling cytokine involved in type 2 immune responses.
Measures soluble interleukin-2 receptor alpha (sIL-2R/CD25), an immune-activation marker associated with activated T-cell signaling.
