Special Info
Place whole blood on ice immediately after collection. Deproteinize whole blood within 30 minutes of collection to stop additional evolution of lactate/pyruvate. Specimen processing / deproteinization instructions: Collect one 5 mL gray (sodium fluoride/potassium oxalate) tube. Within 30 minutes of draw, add 1 mL well mixed blood to 2 mL cold 12% TCA. Repeat with separate 1 mL of oxalated whole blood into a second tube of cold 12% TCA. (Note: 1:2 ratio of blood to 12% TCA must be maintained for accurate quantitation). Vortex precipitation tubes vigorously and refrigerate or place on wet ice for 10 minutes. After 10 minutes of cold incubation, centrifuge for 10 minutes at 1000G. Decant supernatant into a clean, well-sealed transport tube. Label tube as "TCA Precipitate". Precipitated sample can be transported at refrigerated temperature. *Stability Information is for precipitated sample.
