A method for detecting lysergide (LSD-25) in urine is described, using solvent extraction and thin-layer chromatography. The procedure concentrates the drug from a 25 ml urine sample, hydrolyzes it to iso-lysergic acid, and then extracts and chromatographs the product. The limit of detection is approximately 0.5 micrograms per milliliter of urine. The test is intended for routine screening in clinical or forensic settings.
