Basic drug detection method |
| abstract |
A method for detecting basic narcotics or drugs in body fluids which comprises filtering body fluids through a cellulosic filtering means treated with a binding agent for the narcotics or drugs and the filtering means. The binding agent is a polycarboxylic acid. The narcotics or drugs are then treated with a subsequent reagent to produce a color reaction. A device for detecting basic narcotics or drugs in also disclosed which contains the filtering means treated with the binding agent so as to concentrate the narcotic or drug prior to reaction with a suitable indicator. |
