Specimen Collection Requirements:
Patient Preparation: Patients in outlying areas should be encouraged to have their blood tests within an 
hour of the courier collect to minimise transport affect.  Courier collect times 
are listed with the opening hours for each area.

Additional Information: For visits marked "URGENT" collected in the Hutt lab, samples should be taxi'd 
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 samples. The samples 
are placed in a red candy striped bag so that they are processed urgently. 

Hutt lab should call Wellington lab reception number 04 245 0209 (ext 4209) to let 
them know to expect the sample. After hours this should divert to the hospital 
bench as reception is not staffed after 6pm M-F and weekends. Wellington reception 
/ hospital bench will deliver the sample straight to Haematology upon receipt.
