The VARIANT II™ is a fully automated analyzer that requires no sample preparation and very little hands-on time by the operator. The VARIANT II™ Sampling Station accepts bar coded primary specimen tubes. It reads the bar code, samples from the closed tube, dilutes and injects the specimen into the Chromatographic Station for analysis. The results are processed by Bio-Rad's Clinical Data Management Software™ (CDM). CDM™ can be interfaced to the laboratory information system for real time data transmission and superior data management. Bio-Rad provides complete assay kits for analysis of HbA1c, Total GHb and b-thalassemia on the VARIANT II™ system.
