Appendix: Common Steroid Identification—GC-MS Mass Spectra Gary Woodward, Francis Lam, and Gill Rumsby As described in Chap. 3, steroid profiling in the context of steroidogenic conditions is performed by GC-MS analysis following conjugate hydrolysis and derivatisation. Below are the mass spectra used for identification of urine steroids described throughout this book, and compiled during routine practice within our laboratory. Steroids are given in approximate order of their retention times.
