title: [Immunoassay methods used to diagnose patients poisoned with psychoactive substances--analytical and interpretation problems].
abstract: Diagnostics of patients poisoned with psychoactive substances is usually performed by immunoenzymatic methods. The results obtained by the methods are not reliable. A few percent of results can be "false positive" or "false negative". The purpose of the paper was to present cases of "false positive" THC and amphetamine derivatives results obtained in urine of patients treated in Departments of Toxicology in Krakow and in Tarnow. Confirmation tests gave negative results. Interpretation of results obtained by immunoassay methods should include possibility of "false" result. The physician should consider verification of the results and refer confirmation by reference methods.
