Test Code 5472267 ACTIVATED PROTEIN C RESISTANCE

Test ID

1233000095

Specimen Requirements

Collection Requirements Specimens should be collected in 2-3 mL 3.2% sodium citrate (light blue top) tubes from peripheral veins, when possible. When drawn from an indwelling line, 5 ml saline flush followed by 5 ml discard tube should be performed. Do not under or over-fill collection tubes. Gently invert the tube end-over-end 8-10 times. If hematocrit is >55%, contact coagulation lab prior to sample collection.
Shipping / Handling Instructions Outpatient specimens: Specimens should be centrifuged and frozen within 4 hours of collection to generate platelet-poor plasma. A minimum of 0.5 ml frozen citrated plasma is needed per test ordered.
Inpatient specimens: Transport at room temperature. Specimens should be received in lab within 2 hours of collection.
