Reflex Criteria:
If the PT is prolonged (> 13.5 seconds), the PT-Mix is performed at an additional charge (CPT code(s): 85611).

If the PTT-LA is prolonged (> 40 seconds), the PTT-LA Mix is performed at an additional charge (CPT code(s): 85732).

If the PTT-LA Mix corrects, an Incubated PTT-LA Mix is performed at an additional charge (CPT code(s): 85732).

If PTT-LA Screen is prolonged (>40 seconds), then Hexagonal Phase Confirmation will be performed at an additional charge (CPT code(s): 85598).

If dRVVT screen is prolonged (>45 seconds), dRVVT Confirmation will be added at an additional charge (CPT code(s): 85597).

If the dRVVT Confirm is positive, a dRVVT 1:1 dilution will be added at an additional charge (CPT code(s): 85613).

If the Hexagonal Phase Confirm is positive or weakly positive a Thrombin Clotting Time, will be performed at an additional charge. (CPT code(s): 85670).
