POCT, the full name of Point-of-Care Test in English, is a sub-industry of in vitro diagnostic devices (IVD), which refers to rapid diagnosis around patients, so it is called point-of-care testing. POCT can quickly and appropriately conduct diagnosis and treatment, nursing, and disease course observation, thereby improving medical quality and patient satisfaction. Due to a series of advantages such as instrument portability, easy operation, and timely and accurate results, POCT has been widely used in ICU, surgery, emergency, clinics and patients' homes.

The main purpose of POCT is to get experimental results faster. In traditional diagnosis, a lot of time is wasted in sample transportation, pre-processing, labeling, input, distribution, etc., and the core reaction and analysis time accounts for a very small proportion. In contrast, POCT has a streamlined procedure that greatly reduces the time to diagnosis.

POCT assumes the functions of a laboratory without the need for traditional hospital laboratory equipment and large spaces. POCT can be done either in a doctor's office or in a moving car. POCT is not limited by time and place, and can provide comprehensive services for patients 24 hours a day.

In the future, POCT products will also integrate remote data terminals and medical resources for optimal treatment while performing convenient and rapid detection and analysis, so as to realize the construction of a real big health system. The establishment of an electronic medical record system can share data, thereby eliminating the need for patients to repeatedly check and carry a large number of medical records and other complicated means, and greatly reduce the workload of the hospital to manually collect and input data.
