Saliva as a diagnostic fluid.
The use of saliva as a diagnostic fluid for various human ailments is gaining popularity as it offers distinct advantages over serum. These include the non-invasive nature of saliva collection compared with phlebotomy, simplicity of collection even for individuals with a modest training and the cost-effective applicability for screening large populations. Whole saliva is most frequently used for diagnosis of systemic diseases since it is readily collected and contains serum constituents while gland-specific saliva is useful for investigating pathology of major salivary glands. Broadly, saliva analysis is currently used for the diagnosis of infectious and malignant diseases, hereditary disorders, autoimmune diseases, and endocrine disorders, as well as for the assessment of therapeutic drug levels, particularly in monitoring drug abuse. This review addresses the current status of salivary diagnostics and their future potential.
