As a diagnostic fluid, saliva offers distinctive advantages over serum because it can be collected non-invasively by individuals with modest training. And also saliva may provide a cost-effective approach for screening of large populations. Analysis of saliva may be useful for the diagnosis of hereditary disorders, autoimmune diseases, malignant and infectious diseases, and endocrine disorders, as well as in the assessment of therapeutic levels of drugs and the monitoring of illicit drug use. https://biomedpharmajournal.org/vol9no2/saliva-as-a-diagnostic-tool/ Saliva Endocrine Bacterial Infection hereditary disorders
