Using biomarker tests in primary care

GPs who use point-of-care biomarkers to test for bacterial infections are less likely to prescribe antibiotics unnecessarily, a Cochrane review shows.

Used as an adjunct to a clinical examination, the researchers suggest point-of-care tests such as C-reactive protein can be a good surrogate marker of infection, and may be particularly useful in assisting doctors in the clinical management of acute respiratory infections (ARIs).
