Answer

Answer

Serum, plasma (with sodium citrate anticoagulant, 3.2%)

Blood is obtained with routine venipuncture. A citrate-containing tube must be properly filled and mixed via inversion. It is transported to the laboratory within 3 hours. If this is not possible, the plasma is separated with centrifugation, frozen, and transported to the laboratory on dry ice.

Panels: DIC
