Dear all, We are currently trying to harmonize our refrence range for Tropnin I with another hospital using the same Abbott system. I am wondering what other Abbott users use as a reference range ? 10% CV or ?99th centile and what is their CV at that level. Kit insert states that 99th centile is 0.028 with 10% CV at 0.032.
