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 ...
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 ...
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.

Rapid strep test kit. A rapid diagnostic test (RDT) is a medical diagnostic test that is quick and easy to perform. RDTs are suitable for preliminary or emergency medical screening and for use in medical facilities with limited resources. They also allow point-of-care testing in primary care for things that formerly only a laboratory test could ...
A NASA illustration of a lateral flow assay. A lateral flow test (LFT), [1] is an assay also known as a lateral flow immunochromatographic test (ICT), or rapid test.It is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment.
An ATE can be a simple computer-controlled digital multimeter, or a complicated system containing dozens of complex test instruments (real or simulated electronic test equipment) capable of automatically testing and diagnosing faults in sophisticated electronic packaged parts or on wafer testing, including system on chips and integrated circuits.
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. [11]
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 ]
