Dear Colleagues,
Is anyone experiencing problems with Randox Immunoassay Control level 3 in the TSH assay on Roche Elecsys/E170?
Each time a new lot number of TSH reagent is started on our E170 the level 3 control shifts up or down, which forces us to adapt the target values. Level 1 and 2 remain stable and patient samples seem to remain stable as well.
With kind regards,
