More on anticoagulant adjustment from Heather DeVries: There is more to our story on adjusting sodium citrate for high hematocrits. We have a pediatric patient who is getting multiple draws, for multiple assays, throughout the day. Sometimes there is PT and/or PTT , but sometimes not. The techs are confused as to when the draw must be in a corrected tube. We all understand how the citrate is affecting the results due to its relationship with calcium, but what about when an anti-Xa level is drawn, or an ATIII (antithrombin, AT ) functional? If those are the only assays ordered, must the tube be corrected? The patient's hematocrit has been hovering around 60%. Thanks, Heather.

One mentioned CLSI guidelines, and when I looked, they keep it very simple, saying that removal of 0.1 mL of citrate will cover hematocrits between 55 and 65%.
