It involves the performance of a test close to the site of patient care to provide immediate results, outside the conventional laboratory environment. Tuberculosis, HIV, hepatitis, influenza, sexually transmitted infections, and tropical diseases such as dengue fever and malaria are some of the major diseases that can be tested using point-of-care testing devices. Rapid diagnosis of an infection benefits patient by facilitating timely access to care and also reduces the probability of disease transmission. Moreover, point-of-care tests help to improve the management of infectious diseases in settings wherein access to quality and timely medical care is difficult. Recent developments in the delivery of healthcare services and diagnostic technology have resulted in an increase in demand for POCT in primary and community care services.
