We are a Children’s Oncology Group (COG)-Approved laboratory. The laboratory is unique in the province of Ontario in having a substantial caseload of specialized testing for the chromosome instability syndromes.

The Cytogenetics Laboratory accepts specimens for genomic microarray testing submitted with a referral of developmental delay and/or multiple congenital anomalies. For more information, please see the Microarray Info Sheet (pdf). Specimens submitted to SickKids for genomic microarray testing must be accompanied by the  Genomic SNP Microarray Test Requisition.

Genomic microarray analysis may be indicated if a diagnosis is not achieved after G-band analysis. Genomic microarray analysis will not detect polyploidy, genomic imbalances of regions that are not represented on the microarray, and low-level mosaicism.

If an abnormality is identified by microarray, peripheral blood specimens for follow up FISH analyses of the patient and parents will be requested in the microarray report to assist with interpretation of the results. For follow-up FISH analyses of abnormal microarray results, specimens should be submitted along with the Constitutional Analysis Requisition.

Requirements and recommendations
  • Patients must have a valid Ontario Health Card number.
  • Pre-test counseling of patients and their families is recommended.
  • Genomic microarray analysis is not recommended for patients with infertility or multiple miscarriages; G-band analysis should be requested for these indications.
  • G-band/FISH analysis should continue to be requested as the front-line test for suspected aneuploidy syndromes including Down syndrome, Trisomies 13 and 18, and sex chromosome aneuploidy, or for patients with suspected chromosomal mosaicism.

The Clinical Fibroblast Service (CFS) is a biorepository service that establishes, banks and distributes fibroblast cell lines, primarily for diagnostic testing. 

All requests must be accompanied by a signed requisition completed appropriately for the required service(s).

Note: Services for research fibroblast and lymphoblastoid cell lines are available at The Centre of Applied Genomics.

Our founding chief: Dr. Laurence E. Becker

March 1943 - July 2002

Laurence E. Becker was the Founding Chief of the Department of Paediatric Laboratory Medicine (DPLM) at The Hospital for Sick Children (SickKids) and Professor, Laboratory Medicine and Pathobiology and Paediatrics at the University of Toronto. He spent his entire career at SickKids, which began in 1972 as a resident in Neuropathology.

Laurence (Larry) Becker graduated from the University of Alberta Medical School in 1967. In 1974, following a postgraduate specialization in neuropathology at the University of Toronto and at the Johns Hopkins Medical School in Baltimore, he joined the staff at SickKids as a neuropathologist. He was appointed Professor, Department of Laboratory Medicine & Pathobiology and Paediatrics at the University of Toronto in 1980, and Pathologist-In-Chief at SickKids in 1994. In 1996, after 22 years at SickKids, he became the first Chief of DPLM.

At SickKids, Dr. Becker’s passion was evident in his leadership of DPLM, and in the diagnostic work he carried out behind the scenes. As Chief of DPLM, Dr. Becker never tired of explaining and arguing for the importance of paediatric laboratory medicine and the specialized knowledge that is required to support an effective diagnostic service for children.

Dr. Becker was considered a world-leading authority on childhood neuropathology. He will be particularly remembered for advancing knowledge of paediatric cerebral tumours and sudden infant death syndrome. Dr. Becker held research grants from a wide variety of Canadian and international sources. He was an invited speaker at scientific meetings around the world and received many awards and honours. He authored more than 325 peer-reviewed publications in scientific journals, 44 book chapters, and more than 300 brief communications.

Dr. Becker founded the DPLM Symposium in 1997 to showcase advances in paediatric laboratory medicine and highlight achievements of the amalgamated department. Since 2003, the Symposium has been named ‘Laurence E. Becker Symposium’ in honour of Dr. Becker’s outstanding contribution to SickKids and the medical profession. This annual symposium is supported in part by the Laurence Becker Fund through SickKids Foundation.
