VIBRIO PARAHAEMOLYTICUS BY PCR

The VIBRIO PARAHAEMOLYTICUS BY PCR test is a molecular diagnostic assay that detects genetic material specific to Vibrio parahaemolyticus in clinical (stool or rectal swab) and food samples. Using real-time PCR technology, the test identifies species-specific targets and common virulence genes to provide a sensitive and specific qualitative result — typically reported as detected or not detected. In Dubai, this home PCR service enables rapid confirmation of seafood‑associated gastroenteritis without the need for a clinic visit, helping clinicians and public‑health teams act quickly.

This test is most useful for people presenting with acute gastroenteritis after consuming seafood, for investigation of suspected foodborne outbreaks, and for targeted screening of high‑risk populations such as the elderly or immunocompromised. Results help guide clinical management and food‑safety decisions; however, PCR detects DNA and does not distinguish live from dead bacteria, so culture and susceptibility testing may be recommended for antimicrobial guidance and public‑health confirmation. Always review PCR findings with a treating physician or local public‑health authority in the UAE for appropriate follow‑up.

• tdh virulence gene (thermostable direct hemolysin)
• trh virulence gene (TDH-related hemolysin)
• Qualitative PCR result (Detected / Not Detected)

• Acute diarrhoea within 72 hours of eating raw or undercooked seafood
• Bloody or severe watery diarrhoea with abdominal cramps and fever

• Persistent gastroenteritis in elderly or immunocompromised individuals
• Pre‑shipment or post‑harvest testing of seafood for food‑safety investigations

• High analytical sensitivity and species‑specific detection
• Rapid turnaround to support timely clinical and public‑health action
• Home sample collection across Dubai for patient convenience
• Detection of key virulence genes (tdh/trh) to inform risk assessment
• Supports outbreak investigation and food‑safety decisions

• Stool sample or rectal swab collected by a trained technician at home
• Avoid starting antibiotics prior to sample collection if clinically safe to do so (consult your physician)
• Ensure sample is stored refrigerated and collected by courier/technician within the specified time window
