Eastern Ontario: Laboratory Service Change Announcement

As of 01 July 2016, CHEO’s Biochemical Genetics Laboratory will no longer be providing prenatal screening (i.e. Integrated Prenatal Screening, First Trimester Screening and Maternal Serum Screening).  These services have transitioned to the laboratory at Mount Sinai Hospital.



Prenatal screening continues to be available.  This laboratory change should not impact your care.



Please refer to this letter to care providers.  This letter was distributed by CHEO to provide information and details about the transition of these laboratory services to Mount Sinai Hospital.

Follow-up services will continue to be offered through the CHEO Prenatal Genetics Clinic.
