Stability (from collection to initiation)

After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)

Performed

Sun-Sat

Methodology

Semi-quantitative Chemiluminescent Immunoassay

Reported

Within 24 hours

Ordering Recommendations

Detect prior exposure to T. gondii.

Reference Interval

Effective March 3, 2014
7.1 IU/mL or less:Not Detected.
7.2-8.7 IU/mL:Indeterminate - Repeat testing in 10-14 days may be helpful.
8.8 IU/mL or greater:Detected.

Interpretive Data

The best evidence for current infection is a significant change on two appropriately timed specimens, where both tests are done in the same laboratory at the same time.

The magnitude of the measured result is not indicative of the amount of antibody present.

This test 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).

Synonyms

  • LAB659

Ordering Recommendations

Detect presence of IgM antibodies to T. gondii. For male patients or nonpregnant female patients with equivocal or positive results, Toxoplasma gondii by PCR (0055591) may also be useful if a specimen can be collected from an affected body site.

Reference Interval

7.9 AU/mL or less:Not Detected.
8.0-9.9 AU/mL:Indeterminate - Repeat testing in 10-14 days may be helpful.
10.0 AU/mL or greater:Detected - Significant level of Toxoplasma gondii IgM antibody detected and may indicate a current or recent infection. However, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection.

Interpretive Data

This test is performed using the DiaSorin LIAISON. As suggested by the CDC, any indeterminate or detected Toxoplasma gondii IgM result should be retested in parallel with a specimen collected 1-3 weeks later. Further confirmation may be necessary using a different test from another reference laboratory specializing in toxoplasmosis testing where an IgM ELISA should be ordered. Caution should be exercised in the use of IgM antibody levels in prenatal screening. Any Toxoplasma gondii IgM in pregnant patients that have also been confirmed by a second reference laboratory should be evaluated by amniocentesis and PCR testing for Toxoplasma gondii.

For male and non-pregnant female patients with indeterminate or detected Toxoplasma gondii IgM results, PCR may also be useful if a specimen can be collected from an affected body site.

This test 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).
