Test Code PFA Platelet Function Analysis
Specimen Requirements
NOTE: DO NOT SEND VIA THE PNEUMATIC TUBE SYSTEM!
Container/Tube: Using a 21 G or larger needle, collect 2 blue top tubes. Blood should be drawn directly into an evacuated plastic or siliconized glass tube 3.2% (0.105M) buffered sodium citrate (1 part anticoagulant to 9 parts blood).
SPECIMEN PROCESSING and HANDLING
Specimens for PFA studies cannot tolerate rough handling, do not travel well and should be drawn in the laboratory collection area instead of the doctor’s office to ensure proper handling of the specimen immediately and eliminate courier time.
TRANSPORT TEMPERATURE
Patient samples are stable up to 4 hours and must be stored at room temperature. For the Col/EPI Test Cartridge, it is recommended that testing not be performed until 10 minutes after blood collection.
