Sample Storage and Retention

  • Pre analysis storage: do not store, send to laboratory within 4 hours.
  • Sample retention by lab: This sample will be retained post-analysis at the Hammersmith Hospital, London.

As Pyruvate Kinase degrades quickly in stored blood, and due to the limited availability of transport to the Hammersmith Hospital, this test is not available as an add-on request.
