Specimen Handling:
For Cytogenetics North at UAHFor Cytogenetics South at ACH
  • Ship at room temperature to Cytogenetics Laboratory via UAH Specimen Control WMC 4B2.10.
  • All specimens should be received in the laboratory on the day of collection. Specimens are received Monday through Friday: 7:30am to 3:00pm.
  • Specimens received at the lab after 3:00pm will be processed the next working day.
  • Specimens received on a Friday after 3:00pm will not get CMA on direct (uncultured specimen); CMA will be performed on cultured cells.
  • If specimens are sent from outside of Edmonton, please call the laboratory at (780) 407-1542 or fax shipping information to (780) 407-3059 to inform the lab of expected arrival times and mode of transport.
  • Ship at room temperature to Cytogenetics Laboratory B0-150 ACH.
  • All specimens should be received in the laboratory on the day of collection. Specimens are received Monday through Friday: 8:00am to 4:15pm.
  • Specimens received at the lab after 2:00pm will be processed the next working day.
  • If specimens are sent from outside of Calgary, please call the lab at 403-955-2886 or fax shipping information to 403-955-3000 to inform the lab of expected time of arrival and mode of transport.



  •  
    Additional Information:Any amniotic fluid sample arriving with a request for only CMA testing, will have pre-analytical Rapid Aneuploidy Detection (RAD) testing added, and possibly reflex Karyotype testing if there is an abnormal RAD result.

    RAD testing is performed and reported by the UAH Molecular Diagnostic Laboratory or by the ACH Cytogenetics Laboratory.
     
    Requisition/Form:All requests MUST be submitted on a Chromosomal Microarray (CMA) requisition form.
    Ensure all sections of the requisition are complete.
