<prompt> Chlaymydia in asymptomatic carriers, the most sensitive test is -Tissue cultureNucleic acid amplification testSerologySerum electrophoresis  <response>: Ans. is b i.e., Nucleic acid amplification test . Recently Nucleic acid amplification tests NAAT, havebeen developed for chlamydial infections. . These tests are well suited for screening asymptomatic carriers as well as diagnosis. . These tests are the most sensitive and specific chlamydial diagnostic methods available, they are also the most expensive. . The tests are ? - Polymerase chain reaction PCR - Ligase chain reaction LCR - Transcription mediated amplification TCR - DNA strand displacement amplification SDA
