Detection of antibodies in saliva--an effective auxiliary method in surveillance of infectious diseases.

Saliva is a body fluid containing antibodies of diagnostic significance. Unlike venipuncture, saliva collection (by brushing the teeth and rubbing the gums) is painless, non-invasive, inexpensive, simple and rapid. By using sensitive immunoassays in salivary specimens it is possible to diagnose immunoglobulins against a wide range of infectious diseases e.g. hepatitis A, B and C, measles, mumps, rubella, human immunodeficiency virus, Epstein-Barr virus, parvovirus B 19, human herpesvirus 6 and Helicobacter pylori infections. Salivary antibody testing may provide better access to epidemic outbreaks, children, large populations, hard-to-reach risk groups and may thus play a major role in the surveillance and control of infectious diseases.
