Erratum: HDV RNA assays: Performance characteristics, clinical utility, and challenges

In the original article by Wedermeyer et al,¹ Table 2 erroneously states that Bosphore HDV Quantification Detection Kit v1 is not calibrated to WHO international standards. This is incorrect. The manufacturer’s instructions for use state the following:

HDV Quantitation Standards were calibrated against the WHO 1st International Standard for Hepatitis D Virus RNA for NAT-based Assays Code 7657/12, by performing multiple assays using various dilutions and testing them in replicates. 1 IU was found to be equal to 3.63 copies/mL.
