Gold:

  1. Allow sample to clot for a minimum of 30 minutes
  2. Spin within two (2) hours of sample collection

Lavender: 

  1. Spin
  2. Transfer the plasma to an AHL False Bottom Plasma/Serum Transport Tube labeled as the appropriate plasma type, within two (2) hours of sample collection

Grey:

If a grey top tube will not reach the Central Laboratory within 24 hours of collection, it should be spun down, and the plasma transferred to an AHL False Bottom Plasma/Serum Transport Tube labeled as NaFl plasma. 

Additional testing cannot be added on to this sample.
