Abstract
The vulnerability of immunocompromised patients to common or opportunistic viral infections is particularly high. The quantitation of viral load in clinical specimens is important for the diagnosis and management of the infection and reactivation in this patient population, particularly transplant recipients. As the new regulation “IVDR” regarding in vitro diagnosis methods is about to come into effect in France, diagnostic laboratories have to implement methods and systems compatible with this new regulation. Technical performance of the AltoStar® Adenovirus (AdV), Cytomegalovirus (CMV) and human Herpesvirus-6 (HHV-6) DNA PCR Kits 1.5 was assessed on the AltoStar Automation system AM16 using reference kits in 146 clinical samples. Overall agreement in clinical specimens was 87.5 % (28/32), 96.8 % (62/64), 100 % (22/22), 100 % (28/28) and 92.8 % (26/28) for AdV, CMV (WB samples and other matrices), HHV-6 A&B respectively. Quantitative results were highly correlated and estimated to be equivalent within a 0.057–0.648 log-amount difference.We found that altona kits on The AltoStar AM16 system are suitable for clinical monitoring of AdV, CMV and HHV-6 in immunocompromised hosts.
