Program:Genetics and Genomics
Test Name:Chromosome Analysis / Karyotype, tissue biopsy (G&G South ACH)
Alternate Test Name:Constitutional Cytogenetics (G&G South ACH)
Performing Site: Alberta Children's Hospital
Performing Dept:Cytogenetics
Availability:Test set-up routinely Monday through Friday (excluding statutory holidays).
TAT:Routine 4 weeks
Preferred Tube/Container:Sterile container containing transport media
Alternate:Sterile container containing RPMI media
Specimen Requirements:Fibroblasts (skin biopsy, fresh surgical specimens)

For stillborn / POC fetal or placental tissues, refer to
Rapid Aneuploidy Detection (RAD), fetal tissue (ACH).
Specimen Processing:DO NOT put tissue is formailn.
DO NOT freeze specimen.
Store at ambient temperature if specimen will be transported to the laboratory within 1 hour of time of collection.
If transport is delayed, store at 4 - 8oC until ready to transport.
Specimen Handling:Transport specimen at ambient temperature if within 1 hour of time of collection. If transport is delayed, transport at 4 - 8oC to the ACH Cytogenetics Laboratory B0-150 as soon as possible.

Specimens should be received during the Cytogenetics Laboratory hours of operation (Monday through Friday 08:00 to 16:15) or stored at 4 - 8oC and forwarded to the laboratory on the next business day.
Additional Information:To order tissue transport media, contact the ACH Cytogenetics Laboratory 403-955-2886.
Requisition/Form:All specimens must be accompanied by a completed Constitutional Cytogenetics Requisition.
Ensure all relevant sections of the requisition are complete.

If a Chromosomal Microarray Analysis will be also be requested on cultured tissue, also provide a completed Chromosomal Microarray (CMA) requisition form.

Multiple specimens from a patient require separate requsition for each specimen.
Comments:For additional information refer to Genetic Laboratory Services webpage or contact ACH Cytogenetics Laboratory 403-955-2886 for questions or priority turn-around.
