Abstract

This study describes a validated LC-MS/MS method for assaying 23 steroids within a single run from 150 μl of human plasma, serum or prostatic tissue homogenate. Isotope-labeled steroids were used as internal standards. Samples were extracted with toluene, and ketosteroids were derivatized with hydroxylamine prior to LC-MS/MS analysis. The steroids were separated on a C18 column and methanol was used as an organic solvent with the addition of 0.2 mM ammonium fluoride to improve underivatized estradiol (E2) ionization. Certified reference serums as well as plasma samples, and homogenates of prostate tissue were utilized in the method validation. The specificity of the method was inspected with a total of 27 steroids. The validation proved that the method was suitable for the quantitative analysis of a wide panel of androgens (testosterone, T (3.3 pM-13 nM); androstenedione, A4 (3.3 pM-13 nM); 5α-androstanedione, DHA4 (13 pM-13 nM); dehydroepiandrosterone, DHEA (67 pM-133 nM); dihydrotestosterone, DHT (33 pM-33 nM); 11-ketodihydrotestosterone, 11KDHT (13 pM-13nM); 11-ketotestosterone, 11KT (33 pM-6.7 nM); 11β-hydroxyandrostenedione, 11bOHA4 (33 pM-13 nM); 11β-hydroxytestosterone, 11OHT (13 pM-33 nM)), as well as estrogens (estrone, E1 (3.3 pM-13 nM)), progestagens (17α-hydroxypregnenolone, 17OHP5 (32 pM-127 nM); 17α-hydroxyprogesterone, 17OHP4 (67 pM-133 nM); progesterone, P4 (3.3 pM-13 nM); pregnenolone, P5 (6.6 pM-13 nM)), and glucocorticoids (cortisol, F (33 pM-134 nM); cortisone E (66 pM-131 nM); corticosterone, B (33 pM-67 nM); 11-deoxycortisol, S (33 pM-66 nM); 21-hydroxyprogesterone, 21OHP4 (32 pM-13 nM)). Furthermore, E2 (335 pM-134 nM) and 11α-hydroxyandrostenedione, 11aOHA4 (33 pM-33 nM) could be analyzed if the concentration in the sample was high enough. In addition, aldosterone, A (128 pM-64 nM) and 11-ketoandrostenedione, 11KA4 (33 pM-13 nM) could be analyzed semiquantitatively. The limits of quantification for all compounds ranged from 0.9 to 91 pg/ml, and from 0.009 to 0.9 pg/mg tissue. Compared to our previous method, this new method also permits the analysis of the more challenging steroids, like DHT, DHEA and P5, and a panel of 11-ketosteroids.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
