Which of the following is the most sensitive method for detecting cervical Chlamydia trachomatis infection?
High-Yield Explanation
PCR and LCR are both sensitive and specific methods for detecting cervical Chlamydia trachomatis infection in women. Nucleic acid amplification test is the most sensitive method for detecting Chlamydia trachomatis in endocervical samples (CDC2002). PCR is a method to amplify minute amounts of genetic material. The reaction can thus be used for detecting very tiny amounts of pathogen. Prerquisite is the preparation of pathogen specific DNA primer.
