Toxoplasmosis Antibody Blood Test (Toxoplasma IgM)

Toxoplasmosis is a common parasitic infection caused by Toxoplasma gondii, typically acquired through contact with cat faeces, contaminated soil, or undercooked meat. While most healthy individuals experience only mild, flu-like symptoms, the infection can pose serious risks to pregnant women, unborn babies, and people with weakened immune systems. This blood test detects IgM antibodies, which are the earliest type of antibody produced by the body in response to a recent or active Toxoplasma infection.

This test is particularly relevant for:

• Pregnant women or those planning pregnancy, as congenital toxoplasmosis can cause serious complications for the baby.
• Immunocompromised individuals (for example, those undergoing chemotherapy, transplant recipients, or people living with HIV), in whom reactivation of a dormant infection can be dangerous.
• Anyone experiencing persistent flu-like symptoms, swollen lymph nodes, or unexplained fever who may have been exposed to known risk factors.
• Individuals who have had contact with cat litter, garden soil, or raw meat and want clarity on their infection status.

Toxoplasma Antibodies
- Toxoplasma IgM (TOXO IgM): Detects IgM-class antibodies produced during the early phase of infection. A positive result can indicate a recent or active infection and is often used alongside other antibody tests to clarify the stage of infection.

Why it matters
Identifying a recent Toxoplasma infection early allows timely clinical management, which is especially critical in pregnancy and in immunocompromised patients. A clear IgM result helps your doctor determine whether further investigation or treatment is needed, giving you and your clinician the information required to protect your health and, where relevant, the health of your baby.
