Enzyme-Linked Immunosorbent Assay
Plasma Na Cit
Patient Preparation: The patient should be in a resting state and the specimen collected in the morning to avoid diurnal variation of results.
Specimen Type: Citrated plasma
Collection Container/Tube: Light-blue top (sodium citrate)
Specimen Volume: 1 mL
Collection Instructions: Draw blood in a light blue-top (Sodium citrate) tube(s). Centrifuge for 10 minutes and carefully remove 2/3 of the plasma using a plastic transfer pipette, being careful not to disturb cells. Deliver to a plastic transport tube, cap, and re-centrifuge for 10 minutes. Use a second plastic pipette to remove plasma, staying clear of the platelets at the bottom of the tube. Send 1 mL of platelet-poor plasma frozen in a plastic vial.
Note: Separate specimens must be submitted when multiple tests are ordered.
