POCT

A clinical laboratory measurement made at the bedside, in the clinic, or in a satellite lab, rather than at a centralized laboratory. POCT is designed to improve the turnaround time and usefulness of lab testing. Examples of POCT are nitrazine strips for measuring vaginal pH, refractometers for measuring urine specific gravity, glucometers for measuring blood sugar, and immunoassays for measuring the creatine phosphokinase isoenzymes, myoglobin, and troponin I.

POCT has both convenience and speed, but critical point-of-care values may not be accurate as tests performed in the clinical laboratory.
The study also details market drivers and restraints; revenue forecasts and major market trends; political, economic, social and technology analysis; as well as a competitive and market share analysis for the total POCT market and each product segment within the United States, Europe, Asia and Australia.
Shivkumar and her colleagues found blood-based POCTs (using serum, plasma, or whole blood) to be the most accurate of the tests evaluated in the included studies, showing 98.
In addition to the benefits mentioned above, the use of POCT may help reduce the frequencies of some of these errors, such as the preanalytical errors associated with inappropriate sampling, inappropriate preparation or packaging of samples, and misidentification of patients (3).
Another example of where POCT has helped clinicians to work to guidelines is in early recognition and management of Acute Coronary Syndromes/NONSTEMIs.
Because all POCT must be covered by a hospital's laboratory license, laboratory administrators need to consider other various points.
s [3] review of a rapid HIV POCT pilot scheme found that one-third of all clients presenting for a test had never previously tested for HIV, of whom 22% said they had never tested before because they had not known where to get tested.
Kalorama notes that a CLIA waiver is highly unusual for a lab developed test (LDT), as such a designation is often used to allow the performance of the test outside of a laboratory at POCT sites such as physician office laboratories (POLs), small outpatient clinic labs and decentralized testing points in hospitals and field sites.
In order for POCT to provide tangible clinical benefit, its results should be actionable and used to make decisions which lead to improved health outcome.
