Toxocara Antibody Test | Roundworm Infection

The Toxocara Antibody Test is for anyone who may have been exposed to Toxocara roundworm, a parasite found in the faeces of infected dogs and cats. Infection (toxocariasis) can follow accidental ingestion of contaminated soil or contact with contaminated surfaces, and it is most often seen in children, gardeners, pet owners, and people who travel to areas with poor sanitation. Many infections are mild or silent, but the parasite can cause persistent symptoms including fever, cough, wheeze, abdominal pain, fatigue, and in more serious cases, eye inflammation or visual disturbance. This test looks for antibodies your body has produced against the parasite, helping to confirm whether Toxocara is a possible cause of your symptoms.

Markers included

Toxocara Antibodies
- Toxocara species antibodies: detects immune response to the roundworm, supporting diagnosis of visceral larva migrans (systemic infection) or ocular larva migrans (eye involvement).

Why it matters

Toxocariasis is easily overlooked because its symptoms overlap with many common conditions. Identifying exposure to Toxocara can explain persistent or puzzling symptoms, guide appropriate treatment, and rule out other causes. Early recognition is particularly important where the eyes are involved, as prompt management helps protect vision. The test gives you and your clinician a clearer picture of whether roundworm infection is contributing to your health concerns.
