For performance of clinical toxicological analyses, relatively few hospital or other service laboratories presently have elegant instrumentation such as gas chromatograph-mass spectrometer-computer interfaces for final measurement or mechanized devices for the prior extractions and sample transfers. Most of the small fraction of hospital laboratories providing analyses for drugs are limited to the use of “kits” using thin-layer chromatography (TLC), or ultraviolet (UV) photometric and, occasionally, gas chromatographic (GC) procedures. Most frequently the determination desired must be specified.
