: 200 - 415 mg/dL
: One 2.7mL Light blue top - 3.2% Sodium Citrate
: Citrated platelet poor plasma - Requires double centrifugation if sending a plasma aliquot. Aliquot(s) must be frozen if not received by lab within two hours of collection.
: Pediatric: One 2.7mL Light blue top - 3.2% Sodium Citrate. Neonatal: One 1.8mL Light blue top - 3.2% Sodium Citrate.
: 1.0 mL plasma
: 1.0 mL plasma
: Room Temperature for Light blue top tube, must be received within two hours of draw. Plasma aliquot(s) must be frozen if not received by lab within two hours of collection.
: Room temperature: 2 hours, Frozen: -70° C for one month
Reasons for Rejection
: Clotted sample, incorrectly filled tubes, incorrect tube type, grossly hemolyzed sample, grossly lipemic sample, grossly icteric sample, whole blood >2.0 hours old
: 2 hours, once received into lab
: At fibrinogen levels < 150 mg/dL, very high levels of circulating fibrin degradation products (such as those seen in thrombolytic therapy) may interfere with the accurate measurement of fibrinogen.
: "Deliver to lab immediately. Tubes must be filled to indicator line and not clotted. Indwelling lines should be flushed with saline only and 5 mL of blood should be discarded prior to collecting samples for coagulation studies. If sending plasma aliquots, DOUBLE CENTRIFUGE plasma samples to produce platelet poor plasma. Samples received from an outside lab must be aliquoted and frozen. Grossly hemlyzed, icteric or lipemic samples may be rejected. Ordering physician name and telephone contact information MUST accompany the sample and request.
