Testing Where Care Happens
Point-of-care diagnostics — testing performed at or near the site of patient care rather than in a centralized laboratory — is decentralizing a core function of medicine. Instead of drawing samples and waiting hours or days for results from a distant lab, clinicians and even patients can obtain answers in minutes at the bedside, in the clinic, at the pharmacy, or at home. This shift, accelerated by the widespread rapid testing of the pandemic, is reshaping how quickly diagnoses inform decisions.
The Speed Advantage
The value of point-of-care testing lies in enabling faster clinical decisions. Rapid results for infections allow immediate treatment decisions and infection control. Bedside blood gas, glucose, and cardiac marker testing speed emergency care. In resource-limited and remote settings, portable diagnostics extend capabilities where laboratory infrastructure is lacking. Home testing empowers patients to monitor conditions and detect problems early. The common thread is compressing the time between question and answer, which often improves outcomes.
Balancing Speed and Accuracy
Decentralized testing involves trade-offs. Point-of-care tests may be less sensitive or specific than laboratory methods, and quality control outside the controlled lab environment requires attention. Interpreting and acting on results appropriately, and integrating them into records, pose challenges. Yet advances in microfluidics, biosensors, and miniaturization continue improving accuracy and expanding what can be tested at the point of care. The trajectory points toward increasingly capable diagnostics available wherever and whenever they are needed. Facilities can source diagnostic equipment and lab supplies from our catalog.
