Alverno Laboratories has issued important updates in March 2025 regarding several tests. The BIOFIRE FILMARRAY Gastrointestinal Panel now shows an increased incidence of false positive Norovirus GI/GII results; providers should verify suspected cases using the Norovirus 1 & 2 PCR test. Additionally, the HIV-1 Viral Load by PCR test carries extended limitations for patients who have received gene therapies using HIV-1 based lentiviral vectors, and it should not be used for screening. The Legionella Antigen Urine test is now restricted to patients 21 years and older, and for Type & Screen Follow-Up Testing, patients with a positive antibody screen should be referred directly to their local hospital. Finally, online supply ordering will be available via the Client Community portal beginning in early March.
