STRAIGHT to Wellington and marked with a fluro sticker saying “Urgent specialist 
coagulation. Forward directly to Haematology ASAP”. The samples are NOT 
centrifuged or separated since they should reach Specialist coagulation within 
the hour. Please ensure that the samples are sent at amibent temp in the chilly 
bin and NOT in a frozen container / next to an ice pack as this will freeze the
