Syphilis Screening (EIA)
| Test Name: | CAPTIA™ Syphilis (T. pallidum)-G |
| Test Methodology: | Qualitative detection of IgG antibodies to T. pallidum by automated enzyme immunoassay |
| Test to be Performed: | Syphilis Screening (EIA) |
| CPT: | 86780 |
| Reflex Testing Criteria: | Syphilis EIA is the first step in the reverse algorithm for syphilis testing. Repeatedly reactive results will be reflexed to RPR titer. |
| Pre-Approval Required: | N/A |
| Accepted Specimens: | At least 1 mL of non-hemolytic, non-icteric, non-lipemic serum in SST (preferrable). EDTA or citrated plasma samples are acceptable. |
| Specimen Stability: | Serum samples should be tested within 5 days of collection. Optimum storage: 2-8°C. For samples that require longer than 5 days storage, serum must be removed from the red cells and stored at -20°C or below. Sera may be frozen and thawed only once. Plasma samples should be tested within 48 hours. Do not freeze plasma. |
| Storage/Transport Conditions: | Specimens should be stored and transported at 2-8ºC. Sufficient frozen cold packs in an insulated cooler can be used to maintain this temperature. |
| Turnaround Time: | 7 business days |
| Reference Range: | Non-reactive |
| Comments: | Reactive treponemal IgG antibody test results usually remain reactive for a lifetime; therefore, antibody indices cannot be used to determine response to therapy. |
