  1. HIGH HEMATOCRIT GUIDE FOR SODIUM CITRATE (LT Blue) TUBES Hematocrits greater than 55% can interfere with Coagulation testing. Use the guide below to determine whether a specimen has a high hematocrit (>55%). If a specimen’s red cell layer is greater than or equal to the “High Hematocrit” line, continue to process specimen and perform the following; For NorDx staff -enter a TSCSA to the order. For Client staff – Note “Possible High Hematocrit” on requisition Maximum Fill Nominal Fill Minimum Fill HIGH HEMATOCRIT LEVEL HIGH HEMATOCRIT LEVEL HIGH HEMATOCRIT LEVEL 2.7 mL Draw Tube

  2. PROCESS TO DETERMINE HIGH HEMATOCRIT RESULT • Factor V Leiden (FVDNA) lavender tube (EDTA) will be flagged with a TSCSA label by Specimen Management if a high Hematocrit is suspected using the high Hematocrit guide for citrate tubes. • Molecular Pathology who receives the FVDNA will aliquot the lavender tube and deliver to Hematology to determine Hematocrit. • Hematology performs Hematocrit and enters Hematocrit result in the PROB line of the TSCSA. Hematology will add the appropriate canned comment; i.e. @NOGO (Unable to perform the following tests: INR, PTT, FIB, TCT PC, PS, ATIII and Lupus due to high Hematocrit. Patient will need to be re-collected with adjusted tube series). • Client Support will complete the CSA as required.
