Oral Fluid as an Object of Noninvasive Laboratory Diagnostics

Abstract

This paper is lecture which deal with the importance of laboratory examination for oral fluid so called “salivadiagnostics”. This paper is clarifying the preanalytical stage (obtaining, storing and transfer of samples) and chemical-microscopic methods (pH, relative density, leukocytes, erythrocytes, protein, glucose) for performing a “dry chemistry” technology. The features some of them and changes of parameters in various diseases (neuropsychiatric, dental, pathology of internal organs, osteoporosis and other ones) are presented. The problems of clinical interpretation of changes of oral fluid as well as future prospects of non-invasive diagnostics have been discussed.
