Ascaris Serology

What Is Ascariasis?

Ascariasis is a parasitic infection of the small intestine caused by the roundworm Ascaris lumbricoides. It is one of the most common helminthic infections worldwide, typically transmitted through ingestion of contaminated food or water containing Ascaris eggs.

Symptoms of Ascariasis

While many cases of ascariasis are mild or asymptomatic, heavier infections may lead to:

Abdominal discomfort

Nausea and vomiting

Diarrhoea

Malnutrition

Intestinal blockage in severe cases

Children are particularly vulnerable to complications due to the parasite's impact on growth and development.

Diagnostic Approach: Serologic Testing for Ascaris

A serologic test is used to detect antibodies in the blood produced in response to Ascaris lumbricoides infection. This blood test helps confirm the diagnosis, particularly when stool sample results are inconclusive or when symptoms are suggestive of parasitic infection.

When Serologic Testing for Ascaris Is Recommended

Persistent gastrointestinal symptoms without clear cause

Travel history to endemic regions

Suspected parasitic infection with negative stool tests

Nutritional deficiencies or unexplained growth issues in children
