Laboratories and regulator misled over antibiotic susceptibility test discs

According to Oxoid's website this disc diffusion method was developed in 1947 and is the most widely used test of antibiotic susceptibility. "Performed with care, using adequate controls, it is as accurate as more costly and complicated tests," it says. 2 However, emails seen by the BMJ suggest that accuracy may not be Oxoid's primary concern.
