Abstract: Sensitive methods using a variety of biomarkers in oral saliva of humans and animals to detect, measure, and quantify the presence of infectious and non-infectious agents and the functional status of living tissues in both (1) biomedical and (2) environmental applications. With the in vivo biomedical applications, saliva samples are taken from human or animal subjects and biomarkers, such as enzyme or antibody levels, are measured. The extent of exposure to an agent is measured by the presence of specific chemical or biological constituents, by the degree of the inhibition of enzymes, or by the changes in the amount of the biochemicals in saliva. With the in vitro environmental applications, enzymes or other biochemicals from animal or human saliva can be used to monitor the presence of toxic or reactive agents in tissue samples, urine, feces, milk, air, water, soil, or plants. The amount of toxicant in samples is estimated from a standard curve for that agent.
