Additional Specimen Collection Information

Heparin plasma (green-top tube) are also acceptable. Care must
be taken not to resuspend cellular material. Hemolyzed specimens
are not acceptable. Lipemic (>2+) specimens must be
ultracentrifuged prior to analysis. Icterus may interfere with
assay. Filter the specimen and transfer plasma to a 2 ml sample cup
for analysis.

Specimen storage and stability:

  • Specimens should be separated from the cells within 2
    hours of collection. Specimens may be at room temperature for up
    to 8 hours. After 8 hours specimens may be stored at
    2-8°C for up to 24 hours.
  • If specimens are to be stored longer than 24 hours they must be
    stored frozen at -20°C or lower. Frozen specimens should be
    thawed only once at room temperature. Do not thaw in a waterbath.
    Thawed samples must be centrifuged for 5 minutes at 2200 RCF prior
    to analysis. Frozen specimens are stable for 6 months.
