Screening

There are two key testing methodologies for urine drug testing — screening and confirmation.

Screening of urine samples are initial, qualitative drug tests conducted to identify classes of drugs present in the urine and typically are done using immunoassay. They rely on a set threshold above which a positive result is produced and therefore do not detect lower concentrations of a drug.

The application of immunoassays as a preliminary test to screen for drugs of abuse allows samples to be tested for the presence of drug or drug metabolites in various sample types. Immunoassay tests are based on the antibody-antigen reaction, which provides a relatively fast and straightforward way of determining if drug metabolites are present in the sample.
