Newborn Screening Ontario
Health Care Providers


Health care providers working at hospitals and practices educate parents, collect samples, ensure requisitions are filled out properly, and promptly send samples to us at Newborn Screening Ontario (NSO). This allows us to provide the best start in life to every baby born in Ontario.

We developed a Newborn Screening Manual as a comprehensive guide for you to ensure that all infants born in Ontario have a high quality newborn screen completed. This manual outlines recommended practices in newborn screening and addresses common questions about screening practices.

Most of your questions can be answered in the most recent version of the Newborn Screening Manual, which can be accessed here: Newborn Screening Manual: A Guide for Newborn Care Providers.

Please contact us if you wish to order a print version of this resource.

In addition to the Newborn Screening Manual, this section of our website also includes easily accessible information about ordering supplies and resources, and answers commonly asked questions about sample collection and sample shipping. Our bulletins can also be found archived here.
