Order Display Name: Geisinger Epic Procedure Code Or ID CPT Code:  

FACTOR X (10) CLOTTING ACTIVITY

ORDERING INFORMATION:
Geisinger Epic Procedure Code: LAB2258         Geisinger Epic ID: 7130

SPECIMEN COLLECTION
Specimen type:
Platelet-poor plasma
Preferred collection container:
Alternate Collection Container:
Other size blue-top (3.2% sodium citrate) tubes (e.g., 1.8 mL, 4.5 mL)
Specimen required:
1 mL aliquot of plasma.
Special notes:
Do not draw blood from a heparinized line. Avoid contaminating the sample with tissue thromboplastin or heparin. Venipuncture must be performed with no trauma. If blood is drawn from an indwelling catheter, flush with 5 mL of saline and discard the first 5 mL of blood collected.

SPECIMEN PROCESSING
Specimen processing instructions:
Centrifuge the citrated blue-top tubes as soon as possible (within 60 minutes) at designated time and speed to obtain platelet-poor plasma (<10,000/µL). Using a plastic pipette, remove 1 mL of plasma and transfer to a plastic polypropylene aliquot tube and label with patient's name and a second patient identifier (e.g., date of birth, medical record number). Freeze upright and transport on dry ice. 
Transport temperature:
Frozen.
Specimen stability:
Frozen: -20°C for 30 days, -70°C for 6 months. Room temperature: 4 hours.
Rejection criteria:
Clotted specimen. Stability limits exceeded. Indications of thaw in transit are sample on slant in aliquot tube or in lid of tube. These samples will be run but will receive a comment of interpret results with caution as thawing suspected.
