With the advent of an increased emphasis on the potential to utilize biomarkers in saliva for systemic diseases, the issue of existing oral disease is an important consideration that could adversely affect the interpretation of diagnostic results obtained from saliva. We addressed the question does a patient’s oral inflammation status confound biomarker levels used in diagnosis of acute myocardial infarction (AMI). The results demonstrated that multiple serum biomarkers and a few salivary biomarkers reflected the cardiac event. Importantly, oral health of the individual had minimal impact on the validity of the serum or salivary biomarker effectiveness.
This manuscript describes programmable Bio-Nano-Chip (p-BNC) approach that serves as miniaturized assay platform designed for the rapid detection and quantitation of multiple analytes in biological fluids along with the specific applications in salivary diagnostics intended for the point of need (PON). Included here are oral fluid-based tests for local periodontal disease, systemic cardiac disease and multiplexed tests for drugs of abuse.
