In Ontario, parents/legal guardians are asked for consent for their baby to have hearing screening. Consent and choice of screening are recorded by dedicated hearing screening staff on an Infant Hearing Program (IHP) form. With the launch of expanded hearing screening, hearing screening staff will also inform parents about the expanded hearing screen and ask for their further consent to test their baby’s dried blood spot for risk markers for permanent hearing loss if their baby is eligible. The name of the person providing consent, their choice, and the initials of the person obtaining consent will be recorded on the IHP form and sent to NSO.
If the parents/legal guardians declined to have a dried blood spot sample taken from their baby for newborn screening purposes, or if the sample is unsatisfactory for testing, expanded hearing screening would not be possible and they will be informed via the IHP.
