At our laboratory we use the Sysmex XN-10 (part of the 9000). The stated linearity for platelets is 2-5000x10E3/uL. We generally buy from CAP for linearity/calibration verification material. I noticed that CAP and Streck only went up to about 2000. How do you validate your analyzer to the stated 5000 or have you changed your AMR?
Thanks!
