Reason for recall

Siemens Healthcare Diagnostics has received complaints that the lyophilized cake is not fully dissolved after the stated time in the MMB calibrator Instructions For Use (IFU). The frequency of this occurrence is low but if it occurs, gel-like clumps may be observed.

Potency and specification recalls happen when a batch tests outside its approved limits for strength, purity or dissolution, which can mean the dose delivered is higher or lower than labelled.
