Gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) are advanced analytical techniques for separating, identifying, and quantifying complex mixtures of substances. Cortisol, cortisone, 8-OHdG, melatonin (6-OHMS), organic acid tests and metabolites related to cortisol are tested by LC-MS/MS. This combines liquid chromatography’s separation capabilities with tandem mass spectrometry’s sensitivity and specificity. Compounds are separated by liquid chromatography and then analyzed in tandem mass spectrometers, where they are ionized, fragmented, and selectively isolated for precise identification and quantification. The remaining hormones are tested by GC-MS. This utilises gas chromatography to separate compounds based on their affinity for a column and their boiling points, followed by mass spectrometry to ionize and analyze the compounds based on their mass-to-charge ratios.
