Primary infection or reactivation of CMV in immunocompromised individuals can lead to serious illness, organ failure, and death. Precise and accurate quantification of CMV is a valuable tool to support clinical decision-making and prevent adverse outcomes in transplant recipients. This international multicenter study evaluated the analytical performance of the Alinity m CMV assay using a commercially available panel (2.30 to 6.60 Log IU\/mL) and clinical performance compared to the Abbott RealTi\n                      <jats:italic toggle=\"yes\">m<\/jats:italic>\n                      e CMV assay and Roche cobas CMV assay run on the cobas 6800 system using deidentified remnant plasma specimens.

The high precision, accuracy, and comparable clinical performance of the Alinity m CMV assay, combined with rapid results reporting, support its use in transplant patient management.\n                    <\/jats:p>\n                    <jats:sec>\n                      <jats:title>IMPORTANCE<\/jats:title>\n                      <jats:p>Cytomegalovirus (CMV) in transplant patients can lead to adverse health consequences. Viral load monitoring is important in post-transplant patient care. Clinical diagnostic laboratories utilize various molecular diagnostic platforms. This study evaluated the Alinity m CMV assay with two commercially available assays: the Abbott RealTime CMV and Roche cobas CMV assays. Our results demonstrated a strong correlation between Alinity m CMV and the comparator assays, ensuring comparable results across these platforms.<\/jats:p>\n                    <\/jats:sec>\n                  <\/jats:sec>","DOI":"10.1128\/spectrum.02009-24","type":"journal-article","created":{"date-parts":[[2025,8,19]],"date-time":"2025-08-19T13:00:21Z","timestamp":1755608421000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["An international multi-site study to evaluate the analytical and clinical performance of the quantitative high-throughput Alinity m CMV assay"],"prefix":"10.1128","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9717-408X","authenticated-orcid":true,"given":"Julie W.","family":"Hirschhorn","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/012jban78","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Pathology and Laboratory Medicine, Medical University of South Carolina","place":["Charleston, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark M.","family":"Sasaki","sequence":"additional","affiliation":[{"name":"Molecular Diagnostics at Abbott","place":["Des Plaines, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan Chin","family":"Tai","sequence":"additional","affiliation":[{"name":"Abbott Laboratories (Singapore) Pte.
