Product Description
STaK-Chex is a whole blood assayed hematology control which offers complete assay values for the five-part white cell differential. White blood cell percentages vary for each cell type and are within clinically significant ranges. The precision and accuracy of the instrument’s laser is controlled each time STaK-Chex is analyzed. The control features vials with pierceable caps for autosampling. Its long shelf life reduces the number of shipments, associated costs and time spent performing lot-to-lot correlation.
