Amniotic, Vitreous, Ocular or Aqueous Fluid
Collection Medium:
Sterile container
Preferred Minimum: 1.0 mL fluid
Absolute Minimm: 0.3 mL fluid

Collect in sterile container: Submit 0.5 mL amniotic fluid. If submitting one of the following vitreous/ocular/or aqueous fluid, collect 0.5 mL if ordering one laboratory test. If multiple tests ordered, collect 1.0 mL of this fluid.
(This amount of sample will perform from 1 up to 4 viral tests).
Delivery Instructions:
Submit specimen to laboratory as soon as possible after collection period is completed.
Turn Around Time:
24 hours upon receipt at reference laboratory
Reference Range:
Negative for the presence of Toxoplasma gondii DNA.
Interpretive Data:
A positive result indicates presence of DNA from Toxoplasma gondii.

Negative results indicate absence of detectable DNA but does not exclude the presence of organism or active or recent disease.
Useful For:
Supporting the diagnosis of acute cerebral, ocular, disseminated, or congenital toxoplasmosis.

This assay is designed for use in patients with a clinical history and symptoms consistent with toxoplasmosis. This test should not be used to screen 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.
