Reagents used for the Quantitative HCV RNA PCR Assay

On June 17, 2005, Roche Diagnostics issued a notice regarding the lot of reagents (17190400) used for the quantitative HCV RNA PCR assay.  This lot of reagents has been in use at UIHC since 5/12/2005.  The reagents systematically underquantify HCV RNA titers by 0.3-0.5 log.  When new and valid reagents for this test are received (expected the week of June 27th), all specimens that yielded positive results with the problem reagents will be retested at no cost to the patient. 

Questions should be directed to Molecular Pathology staff (384-9568).
