Diasorin recently announced that the US Food and Drug Administration has granted 510(k) marketing clearance for their updated molecular respiratory panel, now including SARS-CoV-2 detection. The NxTag Respiratory Pathogen Panel v2, based in Saluggia, Italy, utilizes multiplex PCR to identify 19 viral and two bacterial targets in nasopharyngeal swab samples from patients displaying respiratory symptoms.
Designed for use with the Luminex Magpix instrument, capable of processing 96 specimens per run, the test employs ready-to-use lyophilized reagent wells. Enhancements in the v2 version aim to improve accuracy and user experience, featuring easier-to-identify plate seals. Alongside SARS-CoV-2, the panel identifies infections from other coronaviruses, flu A/B, respiratory syncytial virus, Chlamydia pneumoniae, and Mycoplasma pneumoniae.
Diasorin credits funding from the US Department of Health and Human Services’ Biomedical Advanced Research and Development Authority (BARDA) for the expanded panel’s development. Prior to Diasorin’s acquisition, Luminex had received approximately $5.4 million from BARDA in September 2020 to expand the NxTag RPP assay, enabling inclusion of SARS-CoV-2 and facilitating high-throughput COVID-19 testing.
