A gastrointestinal (GI) panel, also known as a stool PCR (polymerase chain reaction) test, is a comprehensive test used to identify the cause of infectious diarrhoea. It analyses a stool sample to detect the genetic material (DNA or RNA) of various pathogens, including:

• Bacteria, such as Salmonella, Campylobacter, E. coli, and Shigella

• Viruses, such as rotavirus, norovirus, and adenovirus

• Parasites, such as Giardia lamblia and Cryptosporidium

  
  

Why is a Gastrointestinal Panel (Stool PCR) Performed?

A GI panel may be ordered if you are experiencing symptoms of GI infection, such as:

• Diarrhoea (watery stools)

• Abdominal cramps

• Nausea

• Vomiting

• Fever

• Blood or mucus in the stool

The test can help your doctor determine the specific cause of your infection and recommend the most appropriate treatment.
