Correct answer: C. TPHA

  • A. VDRL
  • B. Kahn's test
  • C. TPHA
  • D. Widal test

Explanation

TPHA detects antibodies specifically directed against Treponema pallidum and is therefore a treponemal test. VDRL and Kahn tests are less specific non-treponemal tests, while Widal is used for enteric fever.
