The CDC specifically acknowledges that point-of-care testing simply describes the location at which the testing is performed and not the complexity of the test itself. [42] With technological innovation, more complex tests will be able to be performed at the bedside that may not be CLIA-waived like some other at-home point of care tests that ...
Flow-through tests or immunoconcentration assays [1] are a type of diagnostic assay that allows users to test for the presence of a biomarker, usually a specific antibody, in a sample such as blood. They are a type of point of care test, designed to be used by a healthcare provider at patient contact. Point of care tests often allow for rapid ...
An analyte is a substance, chemical or biological, that is being analyzed using a certain instrument. While point-of-care testing is the quantification of one analyte from one in vitro (e.g., blood, plasma or urine) sample, multiplexed point-of-care testing is the simultaneous on-site quantification of various analytes from a single sample.

Point of care (POC) documentation is the ability for clinicians to document clinical information while interacting with and delivering care to patients. [10] The increased adoption of electronic health records (EHR) in healthcare institutions and practices creates the need for electronic POC documentation through the use of various medical devices.

A test data set is a data set that is independent of the training data set, but that follows the same probability distribution as the training data set. If a model fit to the training data set also fits the test data set well, minimal overfitting has taken place (see figure below). A better fitting of the training data set as opposed to the ...
Point-of-care testing is being developed to speed up the time for testing, and to help practitioners avoid prescribing unnecessary antibiotics in the style of precision medicine. [39] Traditional techniques typically take between 12 and 48 hours, [ 6 ] although it can take up to five days. [ 28 ]
A COVID-19 Rapid Antigen test(top) with a Covid-19 Rapid Antigen and a Influenza A&B Rapid Antigen Test(bottom) A rapid antigen test (RAT), sometimes called a rapid antigen detection test (RADT), antigen rapid test (ART), or loosely just a rapid test, is a rapid diagnostic test suitable for point-of-care testing that directly detects the presence or absence of an antigen.
Then, a periodic test will assure that the device has not become unsafe since the POST. Safety-critical devices normally define a "safety interval", a period of time too short for injury to occur. The self test of the most critical functions normally is completed at least once per safety interval. The periodic test is normally a subset of the POST.
