Amoebiasis Antibody Blood Test (Entamoeba histolytica)

Amoebiasis is an intestinal infection caused by the parasite Entamoeba histolytica. It is most commonly acquired through contaminated food or water in regions where sanitation is limited, and it can also be transmitted through close household contact. Many people carry the parasite without symptoms, while others develop diarrhoea, abdominal pain, bloody stools, or more serious complications such as liver abscesses.

This blood test is for anyone with unexplained persistent diarrhoea, abdominal discomfort, or a history of travel to or residence in an area where amoebiasis is common. It is also useful when a clinician needs to distinguish amoebiasis from other causes of gastrointestinal illness, or to investigate possible spread beyond the gut.

The test looks for antibodies produced by the immune system in response to Entamoeba histolytica. A positive result indicates that the body has encountered the parasite at some point, which helps clinicians decide whether further investigation or treatment is appropriate.

Amoebiasis Antibody
- Amoebiasis antibody (anti-Entamoeba histolytica IgG): Detects antibodies directed against the Entamoeba histolytica parasite, supporting the diagnosis of current or past infection.

Why it matters
Persistent gut symptoms can have many causes, and identifying amoebiasis promptly allows for targeted treatment and reduces the risk of complications such as liver abscess. This test provides a clear, clinically meaningful answer that helps you and your doctor move forward with confidence.
