Clinical use: Steroid profiling is ideal for detection of altered steroid metabolism, whether due to defects in steroidogenic enzymes, associated with certain clinical states (e.g anorexia, porphyrias) or as a result of drug treatment.
Background: Urinary steroid profiling by GC and GC-MS provides qualitative and quantitative data on excretion of steroid metabolites. Most of these originate in the adrenal cortex, while the gonads after puberty contribute to the metabolites of androgens and 17a – Hydroxyprogesterone.A profile provides a composite picture of the quantitatively major biosynthetic and catabolic pathways. This is not synonymous with biological importance: metabolites of cortisol, progesterone, corticosterone and testosterone are readily detected whereas those of oestradiol and aldosterone are not, unless analysed by GC-MS in selected ion monitoring mode.
