  | See special instructions on "Coagulation Studies." 1. Draw blood in light blue-top (citrate) tubes. Spin down, remove plasma, spin plasma again, and place 1.0 mL of citrate platelet- poor plasma in plastic vial. (Glass vials cannot be accepted.) NOTE: A. Patient must not be receiving heparin. B. Double-centrifuged specimens are critical for accurate results as platelet contamination may cause spurious results. 2. For factors V, VIII, XI, and XII, draw blood in light blue-top (citrate) tube as a control specimen from a normal, unrelated person at the same time. Spin down, remove plasma, spin plasma again, and place 1.0 mL of citrate platelet-poor plasma in plastic vial. Label clearly on outermost label NORMAL CONTROL. NOTE: Double-centrifuged specimens are critical for accurate results as platelet contamination may cause spurious results. 3. Freeze patient and control specimens immediately at < or = -40 degrees C, if possible. 4. Send patient and control specimens frozen on dry ice in the same shipping container. NOTE: Each coagulation assay requested should have its own separate set of patient and/or control vials. Multiple requests on 1 sample may cause delays. 5. If priority specimen, mark requisition, give reason, and request a call-back. NOTE: 1. Tests for"Ristocetin Cofactor, Plasma" and "von Willebrand Factor Antigen, Plasma" are recommended in conjunction with assay for factor VIII activity. 2. Please complete a "Coagulation Request Form" and forward it with the specimen. This form is supplied by Mayo Medical Laboratories. Requisitions for this procedure cannot be processed unless the information requested is supplied. |
