Canine Toxoplasmosis
Canine toxoplasmosis is caused by Toxoplasma gondii and may be assessed in dogs with compatible clinical signs or relevant risk factors. Toxoplasma antibody measurement indicates exposure and supports assessment of infection status. Point-of-care quantitative testing can provide an objective antibody result for clinical interpretation.

Clinical Context
Canine toxoplasmosis is caused by Toxoplasma gondii and may be assessed in dogs with compatible clinical signs or relevant risk factors. Toxoplasma antibody measurement indicates exposure and supports assessment of infection status. Point-of-care quantitative testing can provide an objective antibody result for clinical interpretation.
Interpretation should combine the quantitative result with the patient's signalment, history, clinical signs, vaccination or treatment history where relevant, and any other laboratory findings. A single value is rarely diagnostic on its own; serial measurements often provide more useful information.

FAQ
When is Toxoplasma testing considered in dogs?
Testing may be considered when a dog has compatible clinical signs or relevant risk factors, including travel or regional exposure. Interpretation should combine antibody results with clinical signs and other diagnostics.
What does a positive antibody result mean?
A positive antibody result means the animal has been exposed to the pathogen or vaccinated, not necessarily that it is currently sick. A single antibody value is best interpreted with clinical findings.
What is the role of quantitative fluorescence testing?
Quantitative fluorescence immunoassay reports objective, instrument-read concentrations with pg/ml-level sensitivity and CV% <10% precision, which supports monitoring and treatment tracking.
What sample is used for quantitative Toxoplasma antibody testing?
The quantitative Toxoplasma antibody test is performed using serum or plasma (EDTA anticoagulant recommended).
