[Saliva diagnostics: a summary of the expanded possibilities]

Area of Science:

• Biomedical Diagnostics
• Oral Medicine
• Point-of-Care Testing

Background:

• Blood analysis remains the standard in hospitals, but saliva diagnostics are increasingly utilized outside clinical settings due to ease of use.
• Saliva collection is non-invasive, safer, and more cost-effective than blood draws, with saliva secretion rate itself being a diagnostic indicator.
• Low saliva secretion is linked to Sjögren syndrome, dental issues (caries, erosion), Candida infections, and respiratory infections in athletes.

Purpose of the Study:

• To highlight the growing importance and expanding applications of saliva diagnostics.
• To discuss the advantages of saliva analysis over traditional blood testing.
• To explore the potential of emerging technologies in enhancing saliva-based diagnostics.

Main Methods:

• Review of current practices and emerging trends in saliva diagnostics.
• Discussion of saliva's role as a diagnostic parameter.
• Exploration of technological advancements, including biosensors and mobile health applications.

Main Results:

• Saliva diagnostics are becoming more prevalent outside hospitals, offering simpler, safer, and cheaper sample collection.
• Saliva analysis can detect inherited diseases and viral infections (e.g., COVID-19), with on-site tests (e.g., pregnancy, HIV) already available.
• The integration of biosensors and mobile health apps promises significant advancements in the field of saliva diagnostics.

Conclusions:

• Saliva diagnostics present a viable and advantageous alternative to blood tests for a wide range of medical conditions.
• Technological innovations are rapidly enhancing the accessibility and scope of saliva-based health screening.
• The future of diagnostics is increasingly leaning towards accessible, non-invasive methods like saliva analysis.
