In a case of magic mushroom ingestion, psilocin was detected in urine and serum. Most psilocin was excreted as the glucuronide conjugate, so enzymatic hydrolysis is recommended as an initial analysis step. Free psilocin in urine was 0.23 mg/l, total psilocin 1.76 mg/l. In serum, free psilocin was 0.018 mg/l, total psilocin 0.052 mg/l. Serum psilocin was too low for detection with REMEDi HS but was measured using GC-MS with d(3)-morphine as internal standard and silylation with MSTFA.
