Bact. Fragilis DNA BY PCR

The Bact. Fragilis DNA BY PCR test detects genetic material of Bacteroides fragilis using polymerase chain reaction (PCR) from a stool or rectal swab sample collected at home. By amplifying specific DNA targets, the assay provides sensitive and specific detection of the organism even when traditional culture is limited by anaerobic growth requirements.

This test is useful for diagnosing suspected anaerobic gastrointestinal, intra‑abdominal or post‑surgical infections and can support rapid, targeted antibiotic decisions. Home collection across Dubai and the UAE combined with laboratory PCR reporting enables timely clinical action for patients with severe diarrhoea, suspected abscesses, wound infections, or unexplained sepsis where B. fragilis is a concern.

• Bacteroides fragilis DNA (Presence/Absence)
• Cycle threshold (Ct) value — semi‑quantitative indicator of bacterial load
• PCR internal control (assay validity)

• Suspected intra‑abdominal or pelvic abscesses
• Severe or persistent diarrhoea of suspected bacterial origin
• Post‑operative wound infections with anaerobic features
• Suspected bloodstream infection/sepsis where anaerobes are possible
• To guide or monitor targeted antibiotic therapy

• High sensitivity and specificity compared with culture for anaerobes
• Rapid turnaround to support timely treatment decisions
• Convenient home collection service across Dubai and the UAE
• Detects low bacterial loads that may be missed by culture
• Includes internal assay controls to ensure result reliability

• At‑home stool or rectal swab collection by trained technician or guided self‑collection
• If clinically safe, avoid starting antibiotics or disclose recent antibiotic use (consult your physician)
• Keep sample refrigerated and ensure pickup/delivery to the laboratory within 24 hours
• Provide recent clinical history and current medications when booking the test
