HelpTest 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. |
