Blood Spots and Test Results: Retention Practices
During the 2012 legislative session, the Minnesota legislature made changes to Minnesota’s newborn screening law. The revised law sets timelines by which the Newborn Screening Program must destroy newborn screening blood spots and test results.
Unless a parent or guardian gives written consent for extended storage and use, the Newborn Screening Program destroys newborn screening blood spots and test results according to the following timelines:
- Blood spots with negative test results are destroyed at 71 days
- Blood spots with positive test results are destroyed at 24 months
- All test results are destroyed 24 months after they are reported
It is not necessary for parents to direct the Newborn Screening Program to destroy blood spots and test results according to the above timelines. The destruction is required by Minnesota law and happens as part of routine practice.
