Most laboratory results are valid for only a certain time period (laboratory tests shelf-life), after which they are outdated and the test needs to be re-administered. Currently, laboratory test shelf-lives are not centrally available anywhere but the implicit knowledge of doctors. In this work we propose an automated method to learn laboratory test-specific shelf-life by identifying prevalent laboratory test order patterns in electronic health records. The resulting shelf-lives performed well in the evaluation of internal validity, clinical interpretability, and external validity.

Test cost display has been shown to reduce inappropriate laboratory test ordering practices in the United States. Unfortunately, such a system is limited in the Canadian publically funded healthcare e...
We determined the relative strengths of association between 23 most commonly ordered laboratory tests and the adverse outcome as indicators of relative criticalness. The lowest and highest results for...

Laboratory medicine is an important part of the healthcare system and directly contributes to preventive actions, diagnostics, treatment, and management of diseases. The level and quality of the utili...
Background The inappropriate use of laboratory resources, due to excessive number of tests not really necessary for patient care or by failure to order the appropriate diagnostic test, may lead to wro...

Works containing concise background information and directions for activities, including conducting experiments or diagnostic tests in the laboratory.
The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.
Test results which deviate substantially from normal ranges of REFERENCE VALUES or other qualitative results. They trigger CLINICAL LABORATORY SERVICES to place a special alert to ensure PATIENT SAFETY.
Methods, procedures, and tests performed in the laboratory with an intended application to the diagnosis of disease or understanding of physiological functioning. The techniques include examination of microbiological, cytological, chemical, and biochemical specimens, normal and pathological.
Organized services provided by MEDICAL LABORATORY PERSONNEL for the purpose of carrying out CLINICAL LABORATORY TECHNIQUES used for the diagnosis, treatment, and prevention of disease.
