For detailed specimen collection and handling, see Coagulation Specimen Collection Guidelines.
If the patient is on medication, list the medications on the lab requisition. Patient should not have received blood products in the previous 2 weeks. Due to short stability, whole blood specimen tubes must reach the testing department within 4 hours, otherwise submit frozen plasma aliquots. If submitting whole blood, transport at ambient temperature (15-25°C) in original unopened tube. If submitting frozen plasma aliquots, specimens must remain frozen (-20°C) during transport.
STAT Requests: Available 7 days/week. Must notify Special Coagulation Department (503 413-5120) to make arrangements. Specimen must be received by 2 pm at Legacy Central Lab.
