Sample Requirements:

Centrifuge primary citrate samples at 1500g for 15 minutes and then remove the plasma and decant to a sample aliquot tube. Citrated plasma aliquots should be sent frozen and packed with ice in an insulated transport container. Alternatively fresh citrate samples can be sent providing they are received within 24 hours of collection.

Sample Labelling:

A minimum of surname, forename and DOB must be present on each aliquot. (Note: local hospital number cannot be accepted as a third point of ID). We will endeavour to ring urgent results on the contact number you have provided. From time of receipt to sample in the lab, urgent results will usually be available within 6 hours. It remains the responsibility of the requestor to coordinate clinical management based on these results.
