What your results can mean
Reading your report

If the result is outside the usual range
A positive result can support a diagnosis of an amoebic liver abscess or invasive amoebic infection, especially with a matching scan. It can also stay positive after past infection, which is common in India.
Who usually has this test
People with fever and pain in the right upper belly, especially when a scan shows a liver abscess, or with bloody diarrhoea.
Risks and aftercare
A minor bruise may form; your doctor may also arrange an ultrasound of the liver.

Questions about this test
What is an amoebic liver abscess?
It is a pus-filled pocket in the liver caused by the amoeba parasite spreading from the gut. It usually causes fever and right-sided belly pain.
Is a stool test better than a blood test for amoebiasis?
For gut infection, stool tests can find the parasite directly. For liver abscess, the blood antibody test is often more helpful.
How do people catch amoebiasis?
Through food or water contaminated with stool. Safe drinking water and hand washing lower the risk.
