SHIGA TOXIN-PRODUCING E. COLI (STEC) BY PCR

The SHIGA TOXIN-PRODUCING E. COLI (STEC) BY PCR is a laboratory-grade molecular assay performed on a stool specimen to detect Shiga toxin–producing Escherichia coli by identifying stx genes and key virulence markers. This PCR test delivers sensitive and specific results that enable early diagnosis and informed clinical decisions to reduce the risk of complications such as haemolytic uremic syndrome (HUS). Offered as an at-home collection service in Dubai, the test combines convenient sample pickup with fast laboratory turnaround and reporting compatible with UAE clinical and public health requirements.

• stx1 (Shiga toxin 1 gene)
• stx2 (Shiga toxin 2 gene)
• eae (intimin virulence gene)
• rfbO157 (E. coli O157 serogroup marker)

• Acute bloody diarrhoea or persistent diarrhoea
• Severe abdominal cramps with diarrhoea
• After consumption of high‑risk foods (undercooked beef, raw produce, unpasteurised dairy)
• When multiple household or community members have similar gastrointestinal symptoms (suspected outbreak)
• Signs suggestive of HUS (reduced urine output, pallor, easy bruising)

• Rapid, laboratory-grade PCR sensitivity and specificity
• Early detection to guide clinical management and avoid inappropriate antibiotics
• At‑home stool collection and same‑day pickup available in Dubai
• Supports timely reporting and outbreak control with UAE public health authorities
• Reduces risk of complications through faster clinical action

• Fresh stool sample collected in the sterile container supplied with the kit
• Do not start antibiotics before sampling if clinically safe; inform the team if already on antibiotics
• Refrigerate the sample and hand it to the courier within the recommended timeframe (typically within 2–4 hours)
• Provide recent symptom onset, food exposure, travel, and contact history when booking
