For INR (International Normalized Ratio) testing, a blue-top tube containing sodium citrate is typically used. The sodium citrate acts as an anticoagulant, preventing blood from clotting and allowing for accurate measurement of coagulation factors. It's essential to fill the tube to the indicated line to maintain the correct blood-to-anticoagulant ratio for reliable results.
