Testing must be performed within 4 hours of sample collection. Requires a separate aliquot if other coagulation tests are requested.
Platelet Function Analysis (PFA) is strongly dependent on the correct method of blood collection requiring venipuncture through a19-21G needle drawn directly into a full size evacuated sodium citrate tube. Do not draw through a line or port, which may cause platelet clumping and result in specimen rejection. Ensure proper specimen mixing by gently inverting by hand 4 times. Must remain unspun at ambient temp. Testing must be performed within 4 hours of sample collection. PFA requires separate tube; additional samples must be collected if other coagulation tests are requested.
