SAMPLE REQUIREMENTS:
Citrated plasma samples must be ‘double spun’ – Centrifuge primary samples at 2000g for 15 minutes and then remove the plasma and pool into a plastic tube and re-centrifuge this pooled plasma at 2000g for 15 minutes. This should be divided into 3 x 1ml aliquots. All samples should be sent frozen and packed with ice in an insulated transport container. Alternatively fresh citrate samples can be sent providing they are they are received <12 hours after 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 of 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.
