Thin Layer Chromatography (TLC)

TLC involves adding a special solvent to the urine sample which extracts the tested substances. The TLC plate displays color spots on a film, which are then compared to a standardized sample. Errors can result from a misinterpretation of the sample and for this reason, TLC is not widely used. Abstinence or substitution are the only ways to guarantee a negative result with TLC.
