Delivering Specimens



  1. SPECIMEN PICK-UP BOX

After obtaining and identifying the specimen, completing the Laboratory Requisition Form with all information required and marking all requested tests on the form, place specimen in a biohazard plastic bag. The requisition must be placed in an outside pocket or attached by rubber band or tape to the outside of the bag. Do not staple the requisition to the bag.

To avoid contamination of the requisition, do not place the requisition in the bag with the specimen. Place the sealed bag in the Specimen Pick-Up Box located on each ward.


  1. SFGH MESSENGER SERVICE PICK-UP

Specimens will be picked up by the SFGH Messenger Service according to the schedule listed on the next page and delivered to the Laboratory for processing. Specimens obtained after regularly scheduled pick-ups must be sent to the lab by special messenger or ward personnel.


  1. “STAT” SPECIMENS

STAT specimens collected at times when the Messenger Service is not available must be delivered to the Clinical Laboratory (2M) by special messenger, by the physician, or by other personnel. Samples for STAT testing can be sent through the pneumatic tube system. See the table of EMERGENCY TESTS in the section on Emergency (STAT) Services.


  1. HIV-1 VIRAL LOAD TEST

HIV Viral Load tests must be delivered to the Clinical Laboratory Specimen Processing Area for separation of plasma from cells within four hours after collection (collect two 5 mL EDTA-PPT tubes).


  1. TESTS NOT PERFORMED BY THE CLINICAL LABORATORY

Do not send specimens for Public Health or Anatomic Pathology to the Clinical Laboratory. They will be returned to the originator via messenger service.


  1. EXTERNALLY CONTAMINATED SPECIMENS

Hospital employees who handle laboratory specimens have relatively high rates of work-related hepatitis. Loosely-capped containers and soiled requisitions pose a significant risk to all who come in contact with these contaminated materials. Messengers and laboratory staff are instructed to refuse soiled leaking containers and/or soiled requisitions. These specimens will be recorded in the computer.


  1. Pneumatic Tube System:

With specially designed specimen carrier inserts, the pneumatic tube system may be used to send most STAT blood specimens directly to the laboratory at tube station 21 (main laboratory). Exceptions: Blood gas samples,blood cultures, body fluids excluding urine, and microbiology specimens cannot be sent via the tube system.

This system is much faster than messenger service. Use only red carrier tubes to transport specimens. Use only clear carrier tubes to transport requisitions and non-biohazardous papers.
