摘要

Urinary leukotriene E_4 (LTE_4) levels in healthy volunteers were determined using liquid chromatography/ tandem mass spectrometry (LC/MS-MS). LTE_4 and its internal standard were extracted by simple solid-phase extraction and analyzed using LC/MS-MS in the selected reaction monitoring (SRM) model by monitoring the transitions between m/z 438 and m/z 333 for LTE_4 and between m/z 441 and m/z 336 for LTE_4-d_3.
