Toxoplasma gondii by PCR
Also known as: TOXOPCR
Use
This test is used to confirm toxoplasmosis infection in immunocompromised hosts as well as fetuses and newborns. It may also be used to confirm equivocal antibody testing results, providing a definitive diagnosis for patients at risk of severe complications from Toxoplasma gondii.
Special Instructions
This test is New York state approved. Specimen source is required when submitting samples. Ensure the correct type of specimen and compliance with preparation instructions to avoid rejection. Tissue samples should be frozen immediately after collection.
Limitations
A negative test result does not preclude the presence of Toxoplasma gondii DNA, as inhibitors or levels below the assay's detection limit may lead to undetectable concentrations. The test is a Laboratory Developed Test (LDT) and has not been cleared or approved by the FDA, though it is performed in a CLIA certified laboratory.
