[Risks of drug screening using immunoassays]. / Risiken beim Drogenscreening mit Immunoassays.

ABSTRACT

Now-a-days immunoassays are world wide used for the rapid screening of drugs. Despite the fact that they are a highly valuable tool for the test of legal and illicit drugs, there is a non-negligible risk of false positive and false negative findings and many pitfalls must be taken into account when using these tests in an uncritical manner and without valid confirmation procedures.
