Cell-Chex is a body fluid procedural control for red blood cell (RBC) and white blood cell (WBC) counts, crystal identification, and white blood cell differentiation.

Cell-Chex® Auto

The first automated body fluid cell count control designed to provide confidence that instrument counts are accurate.

CVA Linearity Controls

A range of assayed linearity control kits that can be used to verify calibration and patient reportable range of 3-part and 5-part haematology instruments.

Para 12® Plus

A five-part whole blood differential control for the Abbott CELL-DYN 3000, 3200, 3500 and 3700.
