A1c-Cellular is a whole blood control that tests the entire HbA1c procedure, including the lysing of the red blood cell, a step omitted by competitor controls. The ready-to-use liquid control mimics a patient sample and does not need to be reconstituted prior to use, reducing the potential for human error. A1c-Cellular is packaged in convenient cap-pierceable vials for autosampling by analyzer and is available in two clinically significant levels. A1c-Cellular is appropriate for immunoassay and ionic exchange HPLC methodologies and is assayed on the top HbA1c chemistry analyzers.A1c-Cellular is a whole blood control that tests the entire HbA1c procedure, including the lysing of the red blood cell, a step omitted by competitor controls.
