New LC-MS/MS bioanalytical method for quantification of Estradiol and Estrone
A new method has been successfully developed and validated for determination of Unconjugated Estradiol and Estrone in human plasma by LC-MS/MS with LLOQ of 2 pg/mL and 5 pg/mL respectively.
The method involves a liquid-liquid extraction procedure and a subsequent derivatization procedure. Estradiol, Estrone and internal standards are measured by reversed phase ultra-high performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS).
The possible metabolite back conversion has been evaluated during method validation.
This method has been successfully used to analyze samples from different clinical studies and the incurred sample reproducibility has met all acceptance crieria.
The development of this assay adds to the list of high sensitivity methods at Anapharm together with Tiotropium, Fluticasone, Salmeterol, Formoterol or Ethinyl Estradiol.
