Contact Technical Support
Measures oxidized LDL particles, which contribute to atherosclerosis and cardiovascular diseases. Elevated levels indicate increased oxidative stress and a higher risk of developing heart disease.
Plasma (preferred) or Serum (acceptable)
0.5 mL
Lavender-top (EDTA) tube (preferred) or gel-barrier tube.
Overnight fasting is preferred
For plasma, draw blood into an EDTA tube and gently invert the tube 8 to 10 times to mix the anticoagulant. Centrifuge the tube, remove the stopper and draw off approximately 2/3 of the upper plasma layer into a labeled transport tube using a transfer pipet bulb. Note: This ensures the buffy coat of white cells and red cells remain undisturbed. Plasma must be separated from cells within 45 minutes of venipuncture. Send plasma in a frozen plastic transport tube. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens on each test requested.
