AbstractLow levels of serum testosterone typically found in women and children cannot be reliably measured by immunoassay. We developed a simple and sensitive method using high-performance liquid chromatography/tandem mass spectrometry (HPLC-MS/MS). Sample preparation involved protein precipitation of serum (1.0mL) with acetonitrile containing the internal standard (testosterone-

Sensitivity And Selectivity

A high-performance liquid chromatography tandem mass spectrometry cubed (HPLC/ MS3) method was developed and validated to quantify lamotrigine in human plasma with carbamazepine as an internal standard. The HPLC/MS/MS system...
