3 An alternative objective might be to reduce morbidity or mortality in persons other than the screened population who might be impacted by a communicable and preventable disease (such as screening for HIV in blood donors 4) among subjects in the population being tested.Īlthough some of the key analytical/statistical results applicable to the design and evaluation of screening tests have been around since the late 1700s, when the Reverend Thomas Bayes first developed the theorem that bears his name and numerous tutorials or review articles have been written more recently ( Alberg et al., 2004 Altman & Bland, 1994a, b, c Deeks & Altman, 2004 Goetzinger & Odibo, 2011 Lalkhen & McCluskey, 2008 Thompson et al., 2005 Zou et al., 2007), there is still some confusion among practitioners about how to interpret and assess the utility of screening tests ( Casscells et al., 1978 Grimes & Schutz, 2002 Manrai et al., 2014 Wegwarth et al., 2012), which is why the article might be of interest to readers of Inhalation Toxicology.įecal immunochemical test (FIT) and the fecal occult blood test (FOBT) interpretation of an x-ray or CT scan, or semi-quantitative analysis by a polygraph operator).Ī major objective of most screening tests is to reduce morbidity or mortality in the population group being screened for the disease by early detection, when treatment may be more successful.

Screening tests may be based on the measurement of a particular chemical in the blood or urine (a quantitative measurement) or some qualitative assessment by a trained observer (e.g. Examples of actual or proposed screening tests include the pap smear for cervical cancer ( Arbyn et al., 2008 Mayrand et al., 2007), mammography (or tomosynthesis) for breast cancer ( Friedewald et al., 2014 Rafferty et al., 2013), PSA (and/or digital rectal exam) for prostate cancer ( Catalona et al., 1991), cholesterol level for heart disease, X-ray (or computed tomography) for lung cancer (discussed below), PKU test for phenylketonuria in newborns, B-natriuretic peptide test for screening patients undergoing echocardiography to determine left ventricular dysfunction ( Maisel et al., 2001), and urinalysis or other screening tests for sexually transmitted diseases or illicit drug use ( Gastwirth, 1987 Jafari et al., 2013 Watson et al., 2002).

Rather subjects who test positive typically require further evaluation with subsequent diagnostic tests or procedures. 2 With few exceptions, screening tests do not diagnose the illness. A screening test (sometimes termed medical surveillance) is a medical test or procedure performed on members (subjects) of a defined 1 asymptomatic population or population subgroup to assess the likelihood of their members having a particular disease.
