Limitations

This assay is designed for use in patients with a clinical history and symptoms consistent with toxoplasmosis and is not for screening healthy patients. Depending on the population, varying percentages of patients may be found to be positive.

Results should be interpreted with consideration of clinical and laboratory findings. A negative result does not indicate absence of disease. Reliable results depend on adequate specimen collection and the absence of inhibiting substances.
