Alverno Laboratories has announced key test updates for April 2025. Quest Diagnostics has discontinued four tests—Adenovirus Antibody, Influenza A and B Antibodies, Influenza Type B Antibody, and the Myocarditis/Pericarditis Panel—with no alternatives available. Effective April 14, BK Virus and Epstein-Barr Virus PCR testing will change units from copies/mL to IU/mL, and specimen requirements will be updated. Complement, Total (CH50) frozen stability will decrease from 30 to 7 days. Yeast susceptibility testing will now be done in-house at Alverno, improving turnaround time to 48 hours. Starting April 21, Quest will no longer accept unpreserved specimens for CMV Rapid Culture; non-bone marrow samples must be collected in VCM.
