<prompt> The most sensitive method for detecting cervical Chlamydia trachomatis infection is:Direct fluorescent antibody testEnzyme immunoassayPolymerase chain reactionCulture on irradiated McConkey cells  <response>: Ans. is c i.e., Polymerase chain reactionRef: Harrison, 17the, p. 1074,19the, p. 1165 and Ananthanarayan, 9the, p. 415Amplification assays such as ligase chain reaction and polymerase chain reaction are the most sensitive chlamydial diagnostic method.Other methods are:a Cell culture: Sensitivity 60-80.b Direct immunofluorescent antibody test: Sensitivity 70-80 and quite specific.c ELISA: 60-80.
