Calibration Verification Assessment 

CVA (Calibration Verification Assessment) and CVA for CELL-DYN are assayed linearity control kits used to determine the patient reportable range and linear performance of 3-part and 5-part hematology instruments by testing the upper and lower limits. Each kit has customized ranges appropriate for each instrument model and provides instrument-specific assay values for the WBC, platelet, RBC, and hemoglobin parameters for select analyzers. WBC and platelet parameters have extended ranges providing values up to 410,000 and 3.5 million for instruments with extended linearities. All kits include WBC, PLT, and RBC/Hgb vials unless otherwise noted.

CVA and CVA for CELL-DYN are available in plastic cap-pierceable vials which allow for autosampling by an analyzer.

Streck offers STATS®, a free Interlaboratory Quality Control program for our customers.
