Multichem P Third-party immuoprotein quality control

Product Description

Technopath Multichem P Supplementary Immunoprotein Control is intended for use as a third party, single level, liquid stable immunoprotein quality control material to monitor the precision of laboratory testing procedures for Immunoprotein Assays on Roche cobas systems.. 

Data for each lot of Technopath’s Multichem QC is pre-configured on the Roche Instrument with the target, range and SD for all analytes.

Barcoded QC tubes allow streamlining of the testing process, and unlike other offerings, barcodes are specific to Roche systems.

The label integrates a 'script zone', which provides space for the laboratory to hand-write the open date, expiry and technologist initials. This elimates the need to apply additional stickers to the QC tubes.

IAMQC® complements Multichem P for Roche, it provides a full suite of QC data management tools, to automate your data collection and analysis.
