Research Progress on Laboratory Technologies for Detection of Tuberculosis

Tuberculosis（TB）is a chronic zoonosis caused by mycobacterium tuberculosis（MTB）,，which is very difficult to diagnose and detect at its early stage. Fortunately,，the technologies of TB laboratory testing and diagnosis has been developing rapidly in recent years. As the main conventional testing technologies，smear and cultivation of sputum are gold standards,，but both of the two technologies have some limitations,，hence，their optimization and improvement have become the important direction for TB testing,，with an emphasis on upgrading of related hardware equipment. In order to solve such limitations,，nucleic acid amplification methods have been studied and explored，including Loop-mediated Isothermal Amplification（LAMP）,，Xpert Mycobacterium tuberculosis/Rifampin（Xpert MTB/RIF）,，crossing priming amplification（CPA），simultaneous amplification and testing（SAT）and PCR. Immunological assays are also used for TB testing,，in which,，T-SPOT.TB and QuantiFERON-Gold test（QFT）have been already developed. Other new technologies are also in development，such as Matrix-assisted laser desorption ionization time-of-flight mass spectrometry（MALDI-TOF-MS）,，metabolic marker testing,，nanopore sequencing，etc. At present,，TB testing methods are turning to immunoassay,，molecular diagnosis and other more accurate methods from traditional bacteriological testing. However,，all the above methods are limited，therefore different technologies should be used together in practice. In conclusion,，the advantages and limitations of various TB testing technologies were summarized,，which would help to select appropriate method in practice.
