In Q4 2024, Alverno Laboratories announced several important updates. They validated new CLSI tobramycin MIC breakpoints for Pseudomonas aeruginosa, which will be implemented using Etest MIC methodology upon request, and Quest Diagnostics discontinued Listeria Antibody by Complement Fixation testing with no replacement offered. Additional changes include a newly available urine drug monitoring test for novel psychoactive substances, a plastic alternative for AFB collection bottles, a new cystic fibrosis sputum culture, the reactivation of certain Streptococcus pneumoniae antibody tests, an updated thyroglobulin assay addressing biotin interference, and the upcoming implementation of 2025 CPT code revisions. These developments may affect diagnostic workflows, test ordering, and patient care strategies at healthcare facilities.
