Abstract

Abstract:

Drug resistant tuberculosis has long been a serious challenge in the field of global public health. At present, it is difficult to provide accurate and effective treatment plans for patients based solely on binary phenotypic drug sensitivity and genotypic drug sensitivity tests. The microbroth dilution drug sensitivity test based on the microplate not only covers a variety of drugs and multiple concentrations at one time, but also provides quantitative drug resistance information for the clinic, so it is receiving more and more attention. In order to use the microbroth dilution drug sensitivity test in a reasonable, scientific, and standardized manner, the Tuberculosis Basic Professional Branch of Chinese Antituberculosis Association had organized experts in relevant fields to formulate this consensus on technical characteristics, application value, standardized operation, result interpretation, and precautions in actual operation of this drug sensitivity method, and proposed 12 recommendations, aiming to provide unified guiding principles for clinical and laboratory staff who are related to tuberculosis.

Key words: Mycobacterium tuberculosis, Microbial sensitivity tests, Broth microdilution, Consensus development conferences as topic
