EDTA:

Immediatley following collection, mix sample by gently inverting 5 times

  

Gold:

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

EDTA

  1. Spin
  2. Transfer plasma to a False bottom plasma/serum transport vial/tube (AHL), labeled as EDTA plasma, within two (2) hours of sample collection
