Overview of the Ascariasis Serology
The Ascariasis Serology blood test measures antibodies associated with exposure to *Ascaris lumbricoides*, a parasitic roundworm responsible for ascariasis.
Ascariasis is acquired when microscopic Ascaris eggs are swallowed, usually through contaminated soil, food or water. Once inside the body, larvae hatch in the intestine, migrate through the liver and lungs, and are eventually swallowed back into the gastrointestinal tract, where adult worms can mature.
The test contains 1 biomarker and is designed to identify an immune response to *Ascaris lumbricoides*. Serology may provide useful supporting information when ascariasis is being considered because of symptoms, travel history, environmental exposure or other clinical findings.
Importantly, this is an antibody test rather than a direct parasite detection test. A positive result can indicate exposure to Ascaris but does not necessarily prove that live adult worms are currently present in the intestine. Antibodies may remain detectable after previous infection or treatment.
Similarly, a negative result does not completely exclude ascariasis, particularly if testing takes place early in the infection before a measurable antibody response has developed. Depending on the clinical circumstances, stool microscopy, imaging, eosinophil measurements or other investigations may also be appropriate.
What Does the Ascariasis Serology Check?
This test measures 1 biomarker.
Ascariasis Serology
Measures antibodies produced by the immune system in response to Ascaris lumbricoides. A detectable antibody response may support evidence of current or previous exposure, but the result should be interpreted alongside symptoms, travel and exposure history, and other parasitological investigations.
Who May Benefit From the Ascariasis Serology?
This test may be suitable for people in whom possible Ascaris exposure or infection is being investigated and where antibody testing could provide additional clinical information.
Recent travel to higher-risk regions - Ascariasis is more common in areas where sanitation is limited and human faecal contamination of soil can occur.
Possible exposure to contaminated soil - Infection can occur after microscopic parasite eggs from contaminated soil are transferred to the mouth.
Possible exposure through contaminated food or water - Poorly washed produce or contaminated water can provide a route of exposure in endemic areas.
Persistent gastrointestinal symptoms - Abdominal discomfort, nausea or changes in appetite may sometimes lead to investigation for intestinal parasites.
Unexplained eosinophilia - Raised eosinophils can occur with several parasitic infections and may prompt further investigation when accompanied by relevant exposure history.
Respiratory symptoms after possible parasite exposure - Larval migration through the lungs can occasionally cause cough or respiratory symptoms during an early stage of infection.
Previous suspected ascariasis - Serology may provide additional supporting information where previous exposure is being investigated.
Further testing after inconclusive parasite investigations - Antibody testing may complement stool or other laboratory investigations in selected circumstances.
Arrange specialist parasite testing privately - Access Ascariasis Serology through London Blood Tests with clinic and home or hotel blood collection options.
How to Prepare
Symptoms and Reasons to Consider the Ascariasis Serology
You may wish to consider the Ascariasis Serology test where symptoms or exposure history raise concern about possible *Ascaris lumbricoides* infection.
Abdominal discomfort or pain - Adult worms live within the intestine, and some infections can be associated with intermittent abdominal symptoms.
Nausea or reduced appetite - Gastrointestinal symptoms can occur in parasitic infections, although these symptoms have many other possible causes.
Abdominal bloating - Persistent bloating may sometimes form part of the clinical picture but is not specific to ascariasis.
Unexplained weight loss - Heavier parasite burdens may affect nutrition, although unexplained weight loss should always be appropriately investigated.
Persistent cough - During larval migration through the lungs, some people may develop cough or temporary respiratory symptoms.
Wheezing or breathing discomfort - Pulmonary migration can occasionally trigger respiratory inflammation during the early phase of infection.
Raised eosinophils on a blood test - Eosinophilia can occur during tissue migration by parasites, although many allergic, inflammatory and infectious conditions can also cause it.
Passing a worm in stool - Visible worms may occasionally be noticed and should prompt appropriate parasitological and clinical assessment.
Recent travel with gastrointestinal symptoms - Travel history can materially alter the likelihood of particular intestinal parasitic infections.
Known or suspected exposure to Ascaris - Testing may be considered where environmental, household or occupational exposure is thought to have occurred.
Ascariasis can be completely asymptomatic, particularly when the parasite burden is low. Symptoms alone cannot establish the diagnosis because gastrointestinal and respiratory complaints overlap with many other conditions.
Serological testing detects the immune response rather than parasite eggs or adult worms. A stool Ova, Cysts and Parasites examination may therefore be useful when established intestinal infection is suspected, particularly once adult female worms are producing eggs.
Seek medical assessment for severe or persistent abdominal pain, repeated vomiting, significant abdominal swelling, breathing difficulty, jaundice or other concerning symptoms. Heavy Ascaris infection can occasionally cause complications such as intestinal obstruction or migration of worms into the biliary or pancreatic system.

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 antibodies associated with Ascaris lumbricoides are assessed through Ascariasis Serology.

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 Ascariasis Serology is approximately 6 business days.
Results are sent securely by email once specialist laboratory analysis and authorisation are complete. Turnaround begins when the laboratory receives your blood sample rather than necessarily from the time it is collected.
Specialist serology may occasionally require repeat analysis or additional laboratory review, which can extend the expected turnaround.
Understanding Your Results
The Ascariasis Serology result reflects whether antibodies associated with *Ascaris lumbricoides* have been detected. The test does not directly identify adult worms, larvae or parasite eggs.
A positive antibody result can support evidence that your immune system has been exposed to Ascaris. However, antibodies may remain detectable following previous infection or successful treatment, so a positive result does not automatically prove that an active intestinal infection is currently present.
A negative result means that detectable antibodies were not identified at the time of testing. This makes significant exposure less likely but does not completely exclude recent or current infection, particularly when the sample was taken soon after suspected exposure.
Where active intestinal ascariasis remains a concern, your GP or specialist may consider additional testing such as stool microscopy for parasite eggs. The appropriate investigation depends on the stage of infection, symptoms, travel history and clinical findings.
Results should therefore be interpreted alongside exposure history, symptoms, eosinophil levels, previous antiparasitic treatment and any other investigations rather than being used as a stand-alone diagnosis.
