Day(s) Performed

Performed: M-F

Routine TAT: 1-3 Days

Intended Use

The IMMULITE 2000 Syphilis Screen test is a treponemal testing procedure for the qualitative detection of antibodies to Treponema pallidum in human serum or heparinized plasma on the IMMULITE 2000 Systems Analyzers as an aid in the diagnosis of syphilis.

The IMMULITE 2000 Syphilis Screen is not intended for use in screening blood or plasma donors.

Specimen Collection and Handling

  • Gold top (SST), or red top (serum).
  • The use of an ultracentrifuge is recommended to clear lipemic samples.
  • Hemolyzed samples may indicate mistreatment of a specimen before receipt by the laboratory; hence the results should be interpreted with caution.
  • Samples that are cloudy or have particulate material should be clarified by low-speed centrifugation.
  • Centrifuging serum samples before a complete clot forms may result in the presence of fibrin. To prevent erroneous results due to the presence of fibrin, ensure that complete clot formation has taken place prior to centrifugation of samples. Some samples, particularly those from patients receiving anticoagulant therapy, may require increased clotting time.

Storage

3 days at 2–8°C; for long-term storage, keep specimens at –20°C.
