• Organophosphorus (OP) compounds are the most extensively used pesticides’ class worldwide; cause most self‑poisoning deaths especially in India. Thus, it is utmost important for early identification and aggressive management of OP poisoning from the clinical perspective to prevent serious complications by using sophisticated LC-MS/MS approach. This was a prospective study involving 103 patients of OP cases admitted to Karnataka Institute of Medical Sciences from June 2022 to May 2023, based on the inclusion and exclusion criteria patients were subjected to study. On admission, venous blood was collected from patient with Malathion and Profenofos OP poisoning history and subjected to serum biomarker and to LC-MS/MS analysis. Out of the 103 patients, 68 patients consumed Profenofos (66%) and 35 patients consumed Malathion (34%). Pseudocholinesterase levels among the of OP cases revealed that the 33 patients had mild toxicity, 40 patients had moderate toxicity and 30 patients had severe toxicity of OP poisoning. Subsequently LC-MS/MS analysis showed that the results obtained are not in correlation with indirect serum marker pseudocholinesterase levels. On the other side, LC-MS/MS results are in correlation with the clinical outcome of the patients with respect to morbidity and mortality. Thus, LC-MS/MS approach to assess the OP levels in patients could be used as potential diagnostic and prognostic marker for the absolute quantification of OP compounds compared to indirect OP levels estimation. •Management of organophosphorus (OP) compound is utmost important.•LC-MS/MS approach to assess the OP levels in patients.•LC-MS/MS results are directly correlated to OP levels in patients.•Outcome of the study could help to frame new clinical guidelines for OP quantification.
