Screening and Diagnostic Testing A1 - Waning, Brenda A1 - Montagne, Michael Y1 - 2001 N1 - T2 - Pharmacoepidemiology: Principles and Practice AB - Screening and diagnostic testing are not primary activities of pharmacoepidemiology, but they are important functions of both public health and epidemiology. Assessing the usefulness of a screening or diagnostic test is based on the sensitivity, the specificity, and the predictive value of the test’s results compared with what is actually occurring. One example of testing that is very pertinent to drug use are tests (e.g., urine, hair, breath) designed to assess whether a person has been using certain psychoactive drugs. But, first, there must be a discussion of data quality, including the concepts of validity and reliability with regard to research results.
