Overview of the Amoebic Antibodies
The Amoebic Antibodies blood test is a specialist serology test used to detect antibodies associated with *Entamoeba histolytica*, the parasite responsible for amoebiasis.
*Entamoeba histolytica* is usually acquired after swallowing food or water contaminated with microscopic cysts of the parasite. Infection is more common in areas where sanitation and access to clean water are limited, although cases can occur in the UK following international travel or other relevant exposure.
The test contains 1 biomarker: Amoebic Antibodies. It measures the immune response to *E. histolytica* rather than looking directly for the parasite itself.
Serology can be particularly useful when invasive or extra-intestinal amoebiasis is being investigated, including suspected amoebic liver abscess. Antibody testing can sometimes provide useful evidence where the parasite is no longer confined to the intestine and stool testing alone may be less informative.
However, a positive antibody result does not necessarily prove that an infection is currently active. Antibodies can remain detectable after previous infection or treatment, particularly in people who have lived in or travelled frequently to areas where amoebiasis is common.
Likewise, a negative result cannot completely exclude infection, particularly when testing is performed early. Results should be interpreted alongside symptoms, travel history, stool investigations, imaging and other clinical findings where appropriate.
What Does the Amoebic Antibodies Test Check?
This test measures 1 biomarker.
Amoebic Antibodies
Detects antibodies associated with Entamoeba histolytica infection. Serology can provide useful supporting evidence when invasive amoebiasis or amoebic liver abscess is suspected, but the result does not independently distinguish active infection from previous exposure.
Who May Benefit From the Amoebic Antibodies Test?
This test may be suitable for people whose symptoms, travel history or other investigations raise concern about possible Entamoeba histolytica infection.
Possible invasive amoebiasis - Antibody testing may provide useful supporting information where E. histolytica has spread beyond the intestinal lumen.
Suspected amoebic liver abscess - Serology can be particularly useful when symptoms or imaging suggest possible amoebic involvement of the liver.
Recent travel to an endemic region - Amoebiasis is more common in areas with inadequate sanitation and contaminated food or water.
Persistent gastrointestinal symptoms after travel - Abdominal symptoms following relevant international travel may warrant investigation for parasitic as well as bacterial causes.
Previous unexplained dysentery - Bloody diarrhoea can occur with intestinal amoebiasis, although several other infections and inflammatory conditions can cause similar symptoms.
Unexplained liver lesion with relevant exposure history - Amoebic serology may be considered as part of a wider investigation where liver imaging and travel history raise suspicion.
Persistent symptoms despite initial gastrointestinal investigations - Specialist serology can sometimes provide additional information when routine investigations have not established the cause.
Known or suspected contaminated food or water exposure - Relevant exposure history can increase the clinical usefulness of targeted parasite testing.
Specialist-requested parasite testing - The test can be arranged privately when recommended by a GP, infectious diseases specialist or gastroenterologist.
How to Prepare
If you have already received treatment for suspected amoebiasis, provide the approximate dates and treatment used when your result is interpreted. Antibodies may remain detectable even after successful treatment.
An accurate travel history is also useful, including countries visited, dates of travel and when symptoms first developed.
Symptoms and Reasons to Consider the Amoebic Antibodies Test
You may wish to consider the Amoebic Antibodies test where *Entamoeba histolytica* infection forms part of the clinical differential diagnosis.
Persistent abdominal pain - Intestinal amoebiasis can cause abdominal discomfort or cramping, although these symptoms have many other possible causes.
Persistent diarrhoea - E. histolytica infection may cause prolonged diarrhoeal illness, particularly following exposure in an endemic region.
Blood or mucus in the stool - Amoebic dysentery can cause bloody or mucus-containing stools and requires appropriate clinical investigation.
Unexplained weight loss - Persistent gastrointestinal infection may contribute to reduced appetite or weight loss, although these symptoms require wider assessment.
Fever following relevant travel - Fever may accompany invasive amoebiasis but also occurs with many other travel-related infections.
Right upper abdominal pain - Amoebic liver abscess may cause pain in the upper right side of the abdomen and requires medical assessment.
Tenderness around the liver area - Liver involvement can cause localised tenderness, although imaging and other investigations are needed to determine the cause.
Persistent fatigue or malaise - Systemic symptoms can occur with invasive infection but are non-specific.
Recent travel with gastrointestinal symptoms - Travel history can substantially alter the likelihood of particular parasitic infections.
Previous stool testing without a clear diagnosis - Serology may provide complementary information where invasive amoebiasis remains clinically suspected.
Many people infected with Entamoeba histolytica have few or no symptoms. Others can develop intestinal disease ranging from diarrhoea to dysentery, while a smaller proportion develop invasive disease outside the bowel.
Amoebic liver abscess is the most common extra-intestinal complication. Symptoms may include fever and right upper abdominal pain, sometimes without prominent diarrhoea at the time of presentation.
Severe abdominal pain, significant rectal bleeding, persistent high fever, jaundice, marked weakness, dehydration or rapidly worsening illness require appropriate medical assessment rather than waiting for routine private blood test results.

Attend your appointment
A trained professional will collect your blood sample safely and efficiently at the clinic or during your arranged home or hotel visit.
Laboratory analysis
Your sample is sent to the laboratory, where Amoebic Antibodies associated with Entamoeba histolytica are assessed using specialist serology.
Receive your results securely
Your results are sent securely by email, ready to review yourself or discuss with a GP, infectious diseases specialist, gastroenterologist or other suitably qualified healthcare professional.
When Will I Receive My Results?
The expected turnaround time for the Amoebic Antibodies test is approximately 4 business days.
Results are sent securely by email once specialist laboratory analysis and authorisation are complete. Turnaround generally begins when the laboratory receives your blood sample rather than necessarily from the time it is collected.
Specialist parasite serology can occasionally require repeat analysis or additional laboratory review, which may extend the expected turnaround.
Understanding Your Results
Your Amoebic Antibodies result indicates whether antibodies associated with *Entamoeba histolytica* have been detected according to the laboratory method used.
A positive result may provide supporting evidence of E. histolytica exposure and can be particularly useful when invasive amoebiasis or amoebic liver abscess is suspected.
However, antibodies may persist after an earlier infection. A positive result therefore does not automatically prove that live parasites are currently present or that E. histolytica is responsible for current gastrointestinal symptoms.
This limitation is particularly important in people who have previously lived in or travelled frequently to regions where amoebiasis is common, as previous exposure may result in persistent antibodies.
A negative result reduces the likelihood of invasive amoebiasis but does not completely exclude infection. The stage of infection, individual immune response and laboratory methodology can all influence serology.
For predominantly intestinal symptoms, direct investigations such as stool microscopy, antigen testing or molecular testing may sometimes provide more useful information about current intestinal infection.
Where liver involvement is suspected, clinicians may consider serology alongside liver imaging, liver function tests, inflammatory markers and other infectious disease investigations. Results should therefore always be interpreted within their clinical context.
