Instructions

Fast 12 hours prior to specimen collection.

NOTE: Testing includes:

  • LDL P, Small LDL P, LDL Size
  • HDL P, Large HDL P, HDL Size
  • Large VLDL P, VLDL Size

Specimen Collection Criteria

Collect: One plain Red-top tube.

Gently invert draw tube 5X (DO NOT SHAKE).

Serum specimens drawn in any other gel barrier collection tube will be rejected, due to interfering substances that make them unacceptable for NMR analysis.

Physician Office/Draw Specimen Preparation

Let specimen clot for 30-60 minutes then centrifuge to separate serum from cells within 8 hours of collection. Transfer serum to a plastic transport tube and refrigerate (2-8°C or 36-46°F).

Preparation for Courier Transport

Transport: 2.0 mL serum, refrigerated (2-8°C or 36-46°F). (Minimum 1.0 mL)

Rejection Criteria

  • Serum Separator (SST) tubes.
  • Gross hemolysis.
  • Gross lipemia.
  • Specimens received on dry ice.
  • Specimens not collected and processed as indicated.

In-Lab Processing

Let specimen clot for 30-60 minutes then centrifuge to separate serum from cells within 8 hours of collection. Transfer serum to a plastic transport tube and refrigerate (2-8°C or 36-46°F).

Transport: 2.0 mL serum, refrigerated (2-8°C or 36-46°F). (Minimum 1.0 mL)

Storage

Specimen Stability for Testing:

Room Temperature (20-26°C or 68-78.8°F): Unacceptable
