Reason for recall

Siemens initiated a recall due to confirmed complaints of low patient sample recovery with Dimension TACR Flex Reagent cartridge (DF107) lot BB4087 and its linked calibrator (DC 107) lot 3BD029. Falsely low Tacrolimus results across the assay range may lead to alterations in dosing.

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.
