Legionnaires’ disease, a serious pulmonary infection caused by Legionella, requires early diagnosis for effective treatment and favorable outcomes. Laboratory diagnostic methods primarily encompass isolation and culture, antigen detection, nucleic acid detection, and serological testing. Although isolation and culture are considered the gold standard, it is characterized by low sensitivity and extended culture duration. Antigen detection offers simple and fast operation but necessitates improved specificity. Nucleic acid detection, although being highly sensitive, has complex operation and high costs. Serological testing provides limited value for early diagnosis. Urine antigen detection, extensively employed globally, is limited to the detection of Legionella pneumophila serogroup I. Novel nucleic acid detection technologies, including digital PCR, isothermal amplification, and next-generation sequencing, present promising applications. Future research should aim to develop more streamlined, rapid, and sensitive detection methods to enhance the early diagnostic rate of Legionnaires’ disease.
