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.

What Is Included?
This gastrointestinal parasite PCR screen detects six parasite-associated organisms in a faeces sample.
Protozoal Parasites
Screens for common protozoal organisms associated with intestinal symptoms and parasitic infection.
Waterborne & Foodborne Parasites
Includes organisms often considered in gastrointestinal illness following contaminated food, water, or exposure risk.
PCR Stool Screen
A molecular faeces test designed to identify parasite genetic material quickly and specifically.
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.
How To Read Your Laboratory Results
Your report will indicate whether parasite genetic material was detected for each organism included in the panel. A detected result should be reviewed with a healthcare professional for clinical interpretation and appropriate next steps.
Results Timeline: Results are typically available within 6 days.
