Objective To analyze and compare the detection method for tuberculosis by immunomagnetic beads capture combined with PCR‐ELISA with double internal standard (IMC‐PCR‐ELISA) and other testing methods, and discuss its clinic application. Methods To tally 102 patients with culture‐positive tuberculosis from sputum were used as positive control, 48 nontuberculosis inpatients with culture‐negative tuberculosis from sputum were used as negative control. And the sensitivity and specificity of smear acid‐fast stain (AFS), immune magnetic beads smear acid‐fast stain method (IMC‐AFS), jinbiao anti‐tuberculosis antibody assay (DICA), ordinary PCR and IMC‐PCR‐ELISA were compared. Results The results showed that the IMC‐PCR‐ELISA could yield quantitative results within about 4. 5 h with a detection limit at 5 copy/μL, the specificity and sensitivity of this method were all 100. 00%. The sensitivity of the AFS, IMC‐AFS, DICA and ordinary PCR were 35. 29%, 43. 14%, 60. 78% and 93. 14%, while the specificity were 95. 83%, 95. 83%, 75. 00% and 91. 67%, respectively. Conclusion Compared with AFS, IMC‐AFS, DICA and ordinary PCR, the IMC‐PCR‐ELISA is rapid, sensitive, secific and quantitative method for detecting tuber‐culosis, which can be taken as a helpful method for rapid detection of TB.
