Blood, plasma and serum are required for this test.
Blood for Sedimentation Rate, Westergren
Specimen must arrive within ≤4 hours of draw.
Container/Tube: Lavender-top (EDTA) tube(s) - No other anticoagulant is acceptable.
Specimen: 5 mL (minimum volume: 1.5 mL) of EDTA whole blood
Transport temperature: Ambient

form.
2. Label specimen appropriately (blood).
Plasma for CRP and Uric Acid
Container/Tube: Light green-top (lithium heparin gel) tube(s)
Specimen: 2 mL (minimum
volume: 1 mL) of lithium heparin plasma
Transport Temperature: Ambient
Collection Instructions: Spin down
immediately and send entire tube to laboratory. If there is a delay
in transport of >8 hours, send specimen refrigerated.
Note: 1. Indicate plasma on request
form.
2. Label specimen appropriately (plasma).
