To determine if the GMNP test has similar diagnostic validity as the GeneXpert molecular method for the diagnosis of pulmonary TB in suspected patients who attend the PCT of the La Libertad Healthcare Network, during January - December 2022 - 2023. Materials and method: An observational, cross-sectional, prospective, analytical, diagnostic test-type study was developed in which, through simple random sampling, patients with suspected pulmonary TB who attended the PCT of the La Libertad Healthcare Network were selected and provided sputum samples for GeneXpert as GMNP and determine diagnostic validity through sensitivity, specificity, positive and negative predictive values, taking culture as the Gold Standard. The diagnostic validity of both tests was compared with the Chi square test, considering a significant value for p < 0.05. Results: 92 sputum samples were collected, subjected to GeneXpert and GMNP testing, and compared to culture. The results were: 38% positive with GeneXpert vs. 39.1% with GMNP; negative 62% with GeneXpert vs. 60.9% with GMNP. The sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy with the GeneXpert were 100%. With GMNP, sensitivity was 100%, specificity 99.2%; positive and negative predictive values of 98.4% and 100% respectively, with diagnostic accuracy of 99.4%. When comparing both tests, no statistically significant differences were observed between the evaluated parameters (p > 0.05). Conclusion: The diagnostic parameters of both tests are similar, so there is also diagnostic correspondence between them. There is no evidence that GeneXpert is better than GMNP or vice versa, therefore, both allow the diagnosis of pulmonary TB by having similar diagnostic validity
