Salivary Cortisol
Cortisol (hydrocortisone, Compound F) is the major glucocorticosteroid hormone produced in the adrenal cortex. Cortisol is actively involved in the regulation of calcium absorption, blood pressure maintenance, anti-inflammatory function, gluconeogenesis, gastric acid, pepsin secretion, and immune function. (1,2,3) Cortisol production has a circadian rhythm. (4) Levels peak in the early morning and drop to the […]
Salivary DNA Analysis
Genotyping creates an inter-individual biological profile that enhances the conclusions of observed abnormalities in participant groups. The SalivaLab’s DNA isolation protocol yields high purity, low salt DNA with A260/A280 ratios (indicating protein content) consistently at or above 1.8 and the A260/A230 ratios at or above 1.5. These high quality results with low sample retest rates […]
Salivary SARS-CoV-2 (IgG) Antibody Panel
The SARS-CoV-2 IgG Antibody Assay, 3-Plex (S-Protein, N-Protein, & RBD) is a serological assay that recognizes antibodies to SARS-CoV-2 Nucleocapsid, Spike 1 and Spike 1 Receptor Binding Domain (RBD) in the same saliva (or serum) sample. Coronavirus antibody testing in saliva has shown utility as a sensitive and specific serum alternative for large scale immune-surveillance […]
Salivary SARS-CoV-2 (N) IgG
There is an urgent need to better understand COVID-19 antibody levels and duration of protective immunity for public health considerations. Coronavirus antibody testing in saliva has shown utility as a sensitive and specific serum alternative for large scale immune-surveillance studies (1). Importantly, IgG in saliva is derived from serum, so specificity and reactivity of salivary […]
Salivary Interleukin-17A
Human Interleukin-17A (IL-17A), is a disulfide linked glycoprotein that is secreted as a 17.5 kDa homodimer mainly by activated T-helper 17 (Th17) cells (1, 2). IL-17A is an important regulator of inflammation whose signaling induces pro-inflammatory cytokines and chemokines that recruit cells of the innate immune system to sites of infection (2). IL-17A also induces […]
Salivary Interleukin-7
Human Interleukin 7 (IL-7) activity is important for every stage of T cell development and survival of naïve T cells and generation and maintenance of CD4 and CD8 T cell memory. It is also important for the formation of lymphoid structure and defense mechanisms mediated by lymphoid cells. Pathologies associated with IL-7 are those mediated […]
Salivary Interleukin-5
Human Interleukin 5 (IL-5), mainly drives the maturation and maintenance of eosinophils and antibody secreting B cells and is a glycosylated 15.2 kDa disulfide linked homodimer mainly produced by eosiniophils (1) and T helper type 2 (Th2) cells (2). Dysregulation of IL-5 is associated with eosinophilia, atopic dermatitis and pulmonary fibrosis. IL-5 is also expressed […]
Salivary Interleukin-13
Human interleukin-13 (IL-13) is secreted by a variety of immune cells as a 15.8 kDa, glycosylated monomeric cytokine involved in a number of biological processes. It stimulates B-cell proliferation, macrophage activation, immunoglobulin production, protein secretion, and phosphorylation of Stat6 protein. IL-13 is a central regulator of IgE synthesis, mucus hypersecretion and a mediator of allergic […]
Salivary Interleukin-12p70
Human interleukin-12p70 (IL-12p70) activates T cells and natural killer cells that stimulate the production of IFN-γ. It is involved in a number of disorders including periodontitis (1) and chronic toxoplasmosis (2) among others. IL-12p70 is a disulfide-linked heterodimer consisting of IL-12a (p35 subunit) and IL-12b (p40 subunit), mainly produced by macrophages and T lymphocytes and […]
Salivary Interleukin-10
Human interleukin-10 (IL-10). IL-10 is mainly produced by monocytes and some lymphocytes as a 20.5 kDa, glycosylated homodimeric protein. It is an anti-inflammatory cytokine that inhibits the synthesis of numerous cytokines (including IFN-γ, IL-2, IL-3, TNF-α, TNF-β, and GM-CSF) that suppress Th1 proinflammatory responses involved in promoting phagocytosis. Secretion is at very low levels in […]
