  2. Indication
    1. Syphilis (Treponema pallidum) detection
    2. Confirmation of positive Screening Test
  3. Background
    1. Antigen Extracts from beef heart (cardiolipin)
      1. Non-specific Syphilis antibodies bind cardiolipin
  4. Labs: Tests for detection of Treponemal Pallidum Antibody

    2. Treponemal antigen precipitates Antibody
      1. Fluorescent Treponemal Antibody (FTA-ABS)
        1. Sensitivity: 80%
      2. Microhemagglutination - Treponema pallidum (MHA-TP)

  5. Labs: Non-Antibody Tests
    1. Dark-field Microscopy
      1. Most specific if Chancre or condyloma is present
      2. Accuracy varies with experience of technician
  6. Protocol: Testing
    1. Screening
      1. VDRL (Venereal Disease Research Lab Test)
      2. RPR (Rapid Plasma Reagin test)
    2. Negative test with lesions present
      1. Repeat screening in 3 weeks
    3. Confirmation of positive Screening Test
      1. Fluorescent Treponemal Antibody (FTA-ABS)
    4. Neurosyphilis CSF Evaluation

  8. Efficacy
    1. Diagnostic Test Sensitivity in Primary Syphilis
      1. Dark-field Exam of Chancre: 80%
      2. Non-Treponemal tests (e.g. RPR): 78-86%
      3. Treponemal tests (e.g. FTA-ABS): 76-84%
    2. Diagnostic Test Sensitivity in Secondary Syphilis
      1. Dark-field Exam of Chancre: 80%
      2. Non-Treponemal tests (e.g. RPR): 100%
      3. Treponemal tests (e.g. FTA-ABS): 100%
    3. Diagnostic Test Sensitivity in Latent Syphilis
      1. Non-Treponemal tests (e.g. RPR): 95-100%
      2. Treponemal tests (e.g. FTA-ABS): 97-100%
    4. Diagnostic Test Sensitivity in Tertiary Syphilis
      1. CSF evaluation required (see below)
      2. Non-Treponemal tests (e.g. RPR): 71-73%
      3. Treponemal tests (e.g. FTA-ABS): 94-96%
