Toxoplasma gondii Antibody, IgG
Also known as: TOXEIGG
Use
This test is utilized for detecting prior exposure to Toxoplasma gondii, which is responsible for the infection Toxoplasmosis. A significant change in antibody levels in appropriately timed specimens is the best evidence for current infection. Testing should not be used for blood donor screening, associated re-entry protocols, or for screening human cell, tissues, and cellular- and tissue-based products (HCT/P).
Special Instructions
Specimens must be labeled clearly as "acute" or "convalescent." Parallel testing is preferred, and convalescent specimens need to be received within 30 days from receipt of acute specimens.
Limitations
The magnitude of the measured result does not indicate the quantity of antibodies present. Indeterminate results (7.2-8.7 IU/mL) may require repeat testing within 10-14 days for better clarification. This test is not suitable for blood donor screening or associated re-entry protocols.
