    • Methods are provided for detecting the amount of one or more HRT panel analytes (i.e., estrone (E1), estrone sulfate (E1s), 17α-estradiol (E2a), 17β-estradiol (E2b), estradiol sulfate (E2s), estriol (E3), equilin (EQ), 17α-dihydroequilin (EQa), 17β-dihydroequilin (EQb), Equilenin (EN), 17α-dihydroequilenin (ENa), 17β-dihydroequilenin (ENb), and Δ8,9-dehydroestrone (dE1)) in a sample by mass spectrometry. The methods generally involve ionizing one or more HRT panel analytes in a sample and quantifying the generated ions to determine the amount of one or more HRT panel analytes in the sample. In methods where amounts of multiple HRT panel analytes are detected, the amounts of multiple analytes are detected in the same sample injection.
    • 提供了用于检测一种或多种HRT面板分析物(即雌酮(E1),硫酸雌酮(E1s),17α-雌二醇(E2a),17β-雌二醇(E2b)),硫酸雌二醇(E2s),雌三醇 E3),平衡(EQ),17α-二氢等位基因(EQa),17β-二氢比例蛋白(EQb),平衡蛋白(EN),17α-二氢马来西林(ENa),17β-二氢马来西林(ENb)和Δ8,9-脱氢雌酮(dE1) )在样品中通过质谱法测定。 所述方法通常涉及将样品中的一种或多种HRT面板分析物离子化并量化产生的离子以确定样品中一种或多种HRT面板分析物的量。 在检测到多个HRT面板分析物的量的方法中,在相同的样品注入中检测到多种分析物的量。
