POCT is the abbreviation of Point of Care Testing, Chinese called "point-of-care testing", which refers to the rapid and convenient testing at the patient's side, which can reduce the sample transfer process and shorten the reporting time. POCT is a fast-growing segment of the in vitro diagnostic industry. The POCT industry has come to the public eye because of the new crown epidemic. Home self-testing has begun to be implemented at home and abroad, which has promoted the growth of the new crown POCT testing market, and the new crown self-test package products have expanded from pharmacies to communities and supermarkets. The self-inspection scene of home and community is one of the existing scenes of POCT products.
