Saliva - A Diagnostic Tool

Saliva has emerged as a promising alternative to traditional serum-based diagnostic tests. This unassuming bodily fluid is rich in locally produced and serum-derived markers, proving its efficacy in diagnosing systemic disorders. Its simplicity, non-invasiveness, and safety for patients and healthcare providers make it a convenient point-of-care diagnostic tool, suitable for monitoring multiple biomarkers in diverse populations. Saliva's cost-effectiveness positions it as a compelling option for large-scale screening. Advancements in diagnostic techniques, such as proteomics and genomics, are expanding its diagnostic potential. Despite challenges, the popularity of saliva in healthcare is on the rise, offering an attractive alternative to invasive and costly diagnostic methods.
