Whether to prescribe an antibiotic is a key issue for clinicians treating respiratory infections in the community.

Point-of-care tests provide results in time to inform treatment. For respiratory infections, the tests can identify the presence of a microbe345 or measure markers of a host’s response to a microbe, such as C reactive protein or procalcitonin, in finger prick quantities of blood.

The only point-of-care tests currently recommended in the UK are urine dipstick for suspected urinary tract infections by Public Health England6 and C reactive protein for suspected pneumonia by the National Institute for Health and Care Excellence.7 Although dipstick, C reactive protein, and procalcitonin point-of-care tests are widely used internationally, the use of C reactive protein and procalcitonin remains rare in UK primary care.

Existing evidence shows that C reactive protein point-of-care …
