Point-of-care diagnostics

Definition

Point-of-care diagnostics refers to medical testing conducted at or near the site of patient care, providing immediate results for clinical decision-making. This approach enhances patient management by enabling rapid diagnosis, often using compact devices that can operate in various settings such as hospitals, clinics, or even at home. The integration of biophotonics and optofluidics technologies in these devices further improves their sensitivity and accuracy, facilitating more effective healthcare delivery.
