Overview of the Strongyloides Antibodies Test
The Strongyloides Antibodies blood test measures antibodies produced in response to Strongyloides stercoralis, a parasitic roundworm capable of causing long-lasting infection.
The test assesses 1 specialist parasitology marker: Strongyloides Antibodies.
Strongyloides stercoralis is a soil-transmitted helminth found particularly in tropical and subtropical regions, although infection can occur elsewhere.
Infection usually begins when infective larvae penetrate exposed skin after contact with contaminated soil.
The larvae migrate through the body before developing into adult worms within the intestine.
Strongyloides has an unusual ability to reinfect the same person internally, a process known as autoinfection.
This means untreated infection can persist for decades after the original exposure.
Many infected people have no symptoms or only mild intermittent symptoms.
Possible manifestations include abdominal discomfort, diarrhoea, skin rash, itching, cough and unexplained eosinophilia.
The infection becomes particularly important before immunosuppressive treatment, especially corticosteroids.
Immune suppression can trigger Strongyloides hyperinfection or disseminated strongyloidiasis, in which large numbers of larvae spread through the body.
This can become life-threatening.
Strongyloides antibody testing is therefore frequently used before significant immunosuppression in people with an epidemiological risk of previous exposure.
Serology is often more sensitive than a single routine stool examination because larval shedding can be intermittent.
However, antibody testing has limitations.
A positive result can represent current or previous infection, and antibodies can remain detectable after treatment.
Cross-reactivity with other helminth infections can also occur.
A negative result reduces the likelihood of infection but may be less reliable in severely immunocompromised people.
What Does the Strongyloides Antibodies Test Check?
The test detects antibodies associated with exposure or infection with Strongyloides stercoralis. This test measures 1 specialist biomarker.
Strongyloides Antibodies
Measures antibodies produced against Strongyloides stercoralis, supporting investigation of chronic infection and screening before immunosuppression where epidemiological risk is present.
Who May Benefit From the Strongyloides Antibodies Test?
Strongyloides serology can be particularly important for people with relevant travel or residence history and before significant immune suppression.
People who have lived in or travelled extensively through endemic regions - Previous exposure can remain clinically relevant many years later.
People with unexplained eosinophilia - Persistent eosinophil elevation can be associated with helminth infection.
People with chronic unexplained gastrointestinal symptoms and exposure risk - Strongyloides can cause intermittent diarrhoea, abdominal discomfort and other digestive symptoms.
People preparing to start corticosteroids - Undiagnosed Strongyloides can become dangerous during steroid-induced immune suppression.
People preparing for chemotherapy, biological treatment or transplantation - Screening can be important before major immunosuppression.
People with a previous positive Strongyloides result - Follow-up testing may form part of specialist management.
People with unexplained recurrent skin or respiratory symptoms and relevant exposure - Larval migration can affect skin and lungs.
People with negative stool parasite testing but persistent clinical suspicion - Serology can be more sensitive than a single stool examination.
How to Prepare
Do not delay urgent clinically required treatment solely for the purpose of laboratory testing.
Where Strongyloides risk is significant before immunosuppression, specialist management decisions may depend on exposure history as well as laboratory results.
Symptoms and Reasons to Consider the Strongyloides Antibodies Test
Chronic Strongyloides infection can be asymptomatic or produce intermittent gastrointestinal, dermatological and respiratory symptoms.
Chronic or intermittent diarrhoea - Intestinal infection can alter bowel function.
Abdominal pain or bloating - Gastrointestinal symptoms can occur during chronic infection.
Unexplained eosinophilia - Elevated eosinophils can be an important clue to helminth infection.
Itchy or rapidly moving skin rash - Larva currens is a characteristic but not universal manifestation.
Unexplained cough or wheezing - Larval migration through the lungs can produce respiratory symptoms.
Unexplained weight loss with relevant exposure history - More significant intestinal disease can affect nutrition.
Previous residence in an endemic region before planned immunosuppression - Infection can persist silently for decades.
A previous positive Strongyloides antibody result - Specialist follow-up can be particularly important before immune-suppressing therapy.
Strongyloides infection can become severe or life-threatening during significant immunosuppression, particularly corticosteroid therapy.
People with epidemiological risk who are about to begin major immune suppression should obtain appropriate clinical assessment rather than relying solely on one private antibody result.
Severe gastrointestinal, respiratory or systemic illness in an immunocompromised person requires urgent medical assessment.
How to Book Your Strongyloides Antibodies Test

Receive your results securely
Your authorised result is delivered securely and can be interpreted alongside travel history, eosinophils and stool parasitology where appropriate.
When Will I Receive My Results?
The current live London Blood Tests page lists a turnaround of approximately 10 days after laboratory receipt for Strongyloides Antibodies.
This is a specialist parasitology serology assay.
The sample undergoes antibody analysis, laboratory quality-control procedures and result authorisation.
Turnaround begins when the specimen reaches the laboratory rather than necessarily from the exact time of collection.
Understanding Your Results
A negative result means Strongyloides antibodies were not detected above the laboratory threshold.
This substantially reduces the likelihood of infection but does not exclude every case.
Sensitivity can be lower in severely immunocompromised people.
A positive result indicates that antibodies to Strongyloides stercoralis have been detected.
This can be consistent with current or previous infection.
Serology cannot reliably prove that live parasites are still present.
Antibodies can remain detectable after successful treatment and can occasionally cross-react with other helminth infections.
Where the result is positive, treatment history, symptoms, eosinophil count and exposure history should be reviewed.
Stool microscopy, concentration techniques or molecular tests may occasionally provide additional evidence.
Before significant immunosuppression, a positive or clinically suspicious result requires appropriate medical management because of the risk of hyperinfection.
Why Book With London Blood Tests?
London Blood Tests provides private Strongyloides serology for parasitic infection assessment and pre-immunosuppression screening.
Detects Strongyloides-specific antibodies - Serology can identify immune exposure even when stool parasite shedding is intermittent.
Important before immunosuppression - Undiagnosed infection can become severe during corticosteroid or other immune-suppressing treatment.
Relevant years after exposure - Strongyloides can persist through internal autoinfection for decades.
Useful with unexplained eosinophilia - Elevated eosinophils can be an important clue.
Can complement stool parasitology - Serology and direct parasite testing provide different information.
Specialist laboratory analysis - Samples undergo dedicated parasitology serology.
Professional blood collection - Clinic and suitable home or hotel phlebotomy appointments are available.
Clear pricing - The Strongyloides Antibodies test costs £154.
