The College of American Pathologists (CAP) is introducing two new requirements for clinical laboratories to use updated breakpoints (BPs) when interpreting antimicrobial susceptibility testing (AST) results. CAP has recognized that some laboratories are using obsolete breakpoints, even when devices have achieved US Food and Drug Administration (FDA) clearance for updates, which could lead to adverse consequences in managing patients.Read More
The US Centers for Disease Control and Prevention (CDC) is tracking multiple cases of monkeypox that have been reported in several countries that don’t normally report monkeypox, including the United States. They are urging healthcare providers in the US to be alert for patients who have rash illnesses consistent with monkeypox and are working with state and local health officials to identify people who may have been in contact with individuals who have tested positive for monkeypox, so they can monitor their health. According to CDC, Monkeypox is rare and does not spread easily between people without close contact. The threat of monkeypox to the general US population remains low.Read More
The CLSI AST Subcommittee has developed and published breakpoints for direct blood culture disk diffusion (DD) testing of several antimicrobial agents for Enterobacterales and Pseudomonas aeruginosa. This project was undertaken to provide antimicrobial susceptibility testing (AST) results earlier than traditional AST methods. Rapidity of susceptibility testing and reporting is particularly important for bloodstream infections. Studies have shown that mortality from sepsis increases every hour that the time to first appropriate antimicrobial is delayed. CLSI developed this method to provide laboratories with a direct-from-blood culture testing approach which is both simple to perform and inexpensive.Read More
