Overview of the Bilharzia Antibody Screen
The Bilharzia Antibody Screen is a specialist serology blood test that detects antibodies produced by the immune system in response to infection with Schistosoma parasites.
Schistosomiasis, also known as bilharzia, is a parasitic infection acquired through contact with freshwater containing infected snails that release microscopic parasite larvae. The infection occurs in parts of Africa, the Middle East, South America and Asia.
The parasites can penetrate intact skin during activities such as swimming, bathing, wading or washing in contaminated freshwater.
The test contains 1 biomarker: Bilharzia Antibody Screen.
Antibody testing is particularly useful when investigating previous exposure because Schistosoma antibodies may remain detectable after infection. This means a positive antibody result demonstrates evidence of exposure but does not necessarily prove that an active infection is still present.
Timing also matters. Antibodies may not become detectable immediately after exposure, so testing too early can produce a negative result despite infection.
Travel history is therefore an important part of interpretation. Details about the country visited, freshwater exposure, timing of travel and any symptoms should be provided wherever possible.
Depending on the suspected Schistosoma species and clinical circumstances, further investigation may include urine testing, stool examination, eosinophil counts, imaging or specialist infectious-disease assessment.
What Does the Bilharzia Antibody Screen Check?
This test measures 1 biomarker.
Bilharzia Antibody Screen
Detects antibodies produced against Schistosoma parasites. A positive result provides evidence of previous or current exposure but does not independently establish whether active infection remains present.
Who May Benefit From the Bilharzia Antibody Screen?
This test may be suitable for people with relevant freshwater exposure in a country where schistosomiasis occurs or where symptoms and travel history raise concern about previous infection.
Freshwater exposure in an endemic country - Swimming, bathing, wading or washing in contaminated freshwater can expose the skin to Schistosoma larvae.
Travel to parts of Africa - Schistosomiasis is endemic in many African countries, making detailed travel history particularly important.
Travel to other recognised endemic regions - Infection also occurs in selected areas of the Middle East, South America and Asia.
Unexplained eosinophilia after travel - Increased eosinophils can occur with parasitic infections and may prompt targeted serological investigation.
Blood in the urine after relevant travel - Urinary schistosomiasis can cause haematuria and requires appropriate investigation.
Persistent abdominal or gastrointestinal symptoms after exposure - Intestinal forms of schistosomiasis can produce abdominal symptoms, although these are non-specific.
Previous unexplained fever after freshwater exposure - Acute schistosomiasis can occasionally cause systemic symptoms several weeks after infection.
Previous positive or borderline Bilharzia result - Repeat or complementary testing may be recommended where an earlier result was unclear.
Specialist-requested tropical disease testing - The test can be arranged privately where a tropical medicine specialist, infectious-disease clinician or GP has specifically requested Schistosoma serology.
How to Prepare
Do not deliberately delay treatment or repeat exposure simply to improve antibody detection.
The laboratory specifically benefits from receiving travel history because geographic exposure, timing and symptoms materially affect interpretation of Schistosoma serology.
Symptoms and Reasons to Consider the Bilharzia Antibody Screen
You may wish to consider the Bilharzia Antibody Screen where relevant travel and freshwater exposure are accompanied by symptoms or unexplained laboratory abnormalities.
Itchy rash following freshwater exposure - Some people develop an early skin reaction where parasite larvae penetrate the skin.
Fever after returning from an endemic area - Acute schistosomiasis can cause a systemic febrile illness several weeks after exposure.
Unexplained eosinophilia - An increased eosinophil count can occur during parasitic infection and may prompt further investigation.
Blood in the urine - Urinary schistosomiasis can cause haematuria, particularly with Schistosoma haematobium infection.
Pain or burning when urinating - Urinary symptoms can occur but also have many more common causes.
Persistent abdominal discomfort - Intestinal schistosomiasis can produce gastrointestinal symptoms in some people.
Diarrhoea or blood in the stool - Intestinal involvement may occasionally cause altered bowel habits or gastrointestinal bleeding.
Unexplained fatigue after relevant travel - Chronic parasitic infection can contribute to non-specific systemic symptoms.
Many people with schistosomiasis have mild or no symptoms, especially during early infection. Absence of symptoms therefore does not completely exclude infection after significant freshwater exposure.
Antibody testing does not reliably distinguish active infection from previous infection because antibodies can remain detectable after successful treatment.
Visible blood in the urine or stool, significant abdominal pain, persistent fever or serious illness following travel should be assessed by an appropriately qualified healthcare professional.
How to Book Your Bilharzia Antibody Screen in London
Booking your Bilharzia Antibody Screen with London Blood Tests is simple and designed to fit around your schedule.
Choose the Bilharzia Antibody Screen
Select the Bilharzia Antibody Screen online and review the included Schistosoma antibody marker before booking.
Select your sample collection option
Choose an in-clinic blood draw (+£35) or a home or hotel phlebotomy visit (+£60) where a qualified phlebotomist collects your sample.
Attend your appointment
A trained professional will collect your venous blood sample and relevant travel history can be provided where required.
Laboratory analysis
Your sample is sent to the laboratory for specialist Schistosoma antibody testing.
Receive your results securely
Your results are sent securely by email, ready to review yourself or discuss with a GP, infectious-disease specialist or tropical medicine clinician.
When Will I Receive My Results?
The expected turnaround time for the Bilharzia Antibody Screen is approximately 10 business days after your sample arrives at the laboratory.
Results are sent securely once specialist serological analysis and laboratory authorisation are complete.
Specialist tropical disease testing may occasionally require additional review or confirmation, which can extend the expected turnaround.
Understanding Your Results
Your Bilharzia Antibody Screen result indicates whether antibodies against Schistosoma parasites have been detected according to the laboratory method used.
A positive result provides evidence that your immune system has been exposed to Schistosoma.
However, antibodies can remain detectable after infection has resolved or after successful treatment. A positive result therefore does not independently prove that live parasites remain present.
A negative result makes exposure less likely but does not always exclude recent infection.
Testing performed too soon after freshwater exposure can be negative before sufficient antibodies have developed.
Where clinical suspicion remains high despite an initial negative result, appropriately timed repeat serology or additional investigation may be recommended.
Further tests can include urine microscopy, stool testing, eosinophil count or imaging depending on the likely Schistosoma species and symptoms.
Results should therefore be interpreted alongside travel history, freshwater exposure, timing, previous treatment and clinical findings.
Why Book With London Blood Tests?

Private Bilharzia Antibody Screen Blood Test in London
London Blood Tests provides the Bilharzia Antibody Screen in London for people requiring targeted investigation following possible exposure to Schistosoma parasites.
The test costs £165 and measures one biomarker: Bilharzia Antibody Screen.
Testing is particularly relevant following freshwater exposure in an endemic region or where travel is followed by eosinophilia, urinary abnormalities or other compatible symptoms.
Clinic appointments are available alongside home and hotel phlebotomy depending on location and availability.
Results should be interpreted alongside travel history and timing because a positive antibody test can reflect past exposure, while very recent infection may initially produce a negative antibody result.
