Which laboratory value is commonly used to assess coagulation status before sheath pull?

Which laboratory value is commonly used to assess coagulation status before sheath pull?

• A. Platelet count
• B. PT
• C. PTT
• D. ACT

Answer: (D)

During endovascular procedures, heparin is given to prevent catheter-related clots, so you need a real-time sense of how anticoagulated the patient currently is. Activated clotting time (ACT) is a point-of-care test performed in the cath lab that measures how long blood takes to clot in the presence of heparin. Because it is rapid and reflects the actual anticoagulant effect at that moment, ACT is the best choice to guide decisions around sheath removal. Platelet count is a static measure of how many platelets are present and doesn’t tell you about the current anticoagulation level. PT and PTT are standard lab tests of coagulation pathways but are slower to perform and don’t reliably reflect the immediate heparin effect during a procedure or how well you’re protected against thrombus during sheath removal. ACT provides the timely, actionable information needed in this setting.
