CLSI recommends that sodium citrate tubes be spun at 1500 RCF for 15 minutes to achieve platelet poor plasma (platelet count < 10, 000) and accurate coagulation test results.
What does sodium citrate do to blood?
Background: Sodium citrate has been used as an anticoagulant to stabilize blood and blood products for over 100 years, presumably by sequestering Ca(++) ions in vitro. Anticoagulation of blood without chelation can be achieved by inhibition of the contact pathway by corn trypsin inhibitor (CTI).
