Objective To analyze the clinical laboratory diagnosis of pathogens in acute respiratory tract infections. Methods 54 patients with acute respiratory tract infection admitted to our hospital were selected as the observation group, and 70 healthy individuals who underwent physical examination during the same period were selected as the control group. Nasopharyngeal secretions and venous blood of the two groups were collected as test samples, and multiple pathogens of the two groups were detected by polymerase chain reaction (PCR). Results The pathogen test results of the observation group were significantly higher than those of the control group, and the differences were statistically significant (P<0.05); The positive results of PCR, IFA, and BLIT tests in the observation group were higher than those in the control group, and the differences were statistically significant (P<0.05). However, there was no statistically significant difference in the positive results of IgM test between the two groups (P>0.05). Conclusion The use of polymerase chain reaction technology for the diagnosis of acute respiratory tract infections has a significant effect. Chlamydia pneumoniae, Mycoplasma pneumoniae, and Coxsackie virus are important pathogens that cause acute respiratory tract infections in patients.
