Because the storage option is a serious matter, parents should ask for the following:

1. Certification for quality assurance from reputable bodies (AABB, Netcord-Fact, UK-NEQAS, E.S.Y.D, etc)
2. If there is cooperation with a hospital or an important scientific research center,
3. If the processing, quality control and storage of the sample takes place in their own laboratories or sample will be sent abroad.
