Behind the Scenes: Understanding Stool Pathogen Testing

Life Sciences, Pharmaceutical, Laboratory Technology,
  • Thursday, June 27, 2024

Stool pathogen testing is important for diagnosing the various causes of diarrheal illnesses. Traditional stool pathogen testing has involved different laboratory methods, leading to specific multiple workflows for bacteria, viruses and parasites.

The introduction of molecular techniques has significantly improved the ability to detect a wide range of gastrointestinal pathogens while offering improved assay performance compared to the non-molecular methods of antigen, culture and/or microscopy.

This webinar will provide an overview of current testing methodologies used in clinical microbiology laboratories and demonstrate how molecular methods could enhance laboratory workflows and aid in patient diagnosis.

Register for this webinar today to understand the clinical and public health significance of molecular gastrointestinal pathogen testing and its impact on diagnosing diarrheal illnesses.
