Department: Haematology
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 effect.  Courier collect times 
are listed with the opening hours for each area.
Phlebotomist Instructions: If this test requires payment please contact Haematology before phlebotomy.
Sample Type:

2x Blue (Sodium Citrate) tube 2.7mL

Minimum Sample Volume: TUBE MUST BE FULL.
Unacceptable Samples: Underfilled, clotted and haemolysed samples.
Transport Requirements: Ambient.
Additional Information: NOTE: if inadequate number of tubes received, please check with department first, 
BEFORE arranging recollection.

Routine hours are 08:30-17:00 Monday - Friday. Outside of routine hours, test must 
be approved by a Haematologist.

For visits marked "URGENT" collected at 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.
