NSO works with Purolator Inc. to ensure timely delivery of samples from submitters all over Ontario to Newborn Screening Ontario’s laboratory at CHEO in Ottawa, ON. Unless otherwise indicated, newborn screening samples should always be shipped via Purolator. Provided the samples are shipped with NSO’s Track-Kit application, shipping costs are billed only to NSO.
Samples should be sent to NSO every business day and Saturdays (for sites with access to Purolator’s Saturday Pickup service). It is extremely important not to wait several days to ship newborn screening samples (this is considered batching). Delays due to sample batching could have serious consequences for affected infants and may render the sample unsatisfactory, requiring a repeat screen, and further delaying the screening process. It is critical that NSO receives newborn screening samples as soon as possible after the blood spots are collected and dried (at least 3 hours after collection). Ship samples every day – even if there is only one ready to send. Purolator pickups can be scheduled daily (Monday-Friday, and Saturday if eligible).
Samples received at NSO more than 14 days after collection are unsatisfactory (even if due to a courier delay), however, they will be analyzed. Screen positive results will be reported. The quality of the results cannot be assured due to possible sample degradation resulting from the length of time since collection and a repeat sample will be required.
To prevent delays and prioritize newborn screening shipments across Purolator’s shipping network, submitters should only ship samples using authorized shipping supplies (Purolator Red Express Pack and Healthcare sticker). To learn more about these supplies, please see our section on shipping supplies.
