Gastrointestinal Screen – Parasites

£76.00

The Gastrointestinal Screen – Parasites (SH23) is a stool PCR test that detects the genetic material of six common intestinal parasites, including Giardia lamblia, Cryptosporidium, and Entamoeba histolytica. This advanced gastrointestinal parasite screen supports the investigation of diarrhoea, abdominal pain, digestive upset, travel-related illness, and suspected parasitic infections. Available at Medical Diagnosis Victoria (MDX Victoria) in London, results are typically delivered within 6 days from a faeces sample.

Screens for common protozoal organisms associated with intestinal symptoms and parasitic infection.

Blastocystis hominis (BH)Dientamoeba fragilis (DF)Entamoeba histolytica (EH)
Clinical focus:Investigating abdominal discomfort, diarrhoea, and suspected protozoal gastrointestinal infection.

Waterborne & Foodborne Parasites

Includes organisms often considered in gastrointestinal illness following contaminated food, water, or exposure risk.

Cryptosporidium spp. (CR)Cyclospora cayetanensis (CC)Giardia lamblia (GL)
Clinical focus:Supporting assessment of diarrhoea, travel-related symptoms, exposure history, and suspected intestinal infection.

PCR Stool Screen

A molecular faeces test designed to identify parasite genetic material quickly and specifically.

Clinical focus:Supporting rapid identification, diagnosis, monitoring, and clinical evaluation of intestinal parasitic infections.

Understanding Gastrointestinal Parasite PCR Testing

PCR testing detects genetic material from parasite-associated organisms in stool. Results should be interpreted alongside symptoms, medical history, travel or exposure history, clinical examination, and any additional laboratory findings.
