Standard or Customizable 903® Newborn Screening Filter Paper

Because neonatal screening is a vital step in monitoring the health of children, it is essential to have dried blood samples also called Dried Blood Spots (DBS) of good quality to ensure reliable and unequivocal testing results.

903 blotting papers provide a safe and proven method to facilitate sample collection, identification and transport. These newborn screening filter papers are subject to very strict quality controls to ensure uniform composition, thickness, absorption and purity. 903® blotting papers are CE marked and in compliance with the 98/79/EC standard. These dried blood test products are validated according to CLSI LA4-A5 consensus standard requirements and are listed as an FDA Class II medical device.

The standards and controls included in the LaCAR neonatal screening kits are produced with 903® blotting papers.

LaCAR offers standard filter papers and also adapts to the needs of each user by customizing production.

LaCAR offers a variety of pre-printed blotting paper formats designed to meet the majority of needs without specific technical constraints. Standard newborn screening filter papers are ready to use and do not need to be adapted, with a design that suits most circumstances.
