The development and establishment of the 1st WHO BKV International Standard for nucleic acid based techniques.

We report on the evaluation of two lyophilised candidate cell culture derived, whole virus preparations, undertaken by 33 expert laboratories. By employing the principles of biological standardisation, we show improved agreement across laboratories, demonstrating the suitability of either candidate for use as a primary order calibrant. Candidate 14/212 was established by the WHO ECBS with an assigned potency of 7.2 log10 International Units/mL intended for the calibration of BKV secondary reference materials.
