Program Information and Tools for NT Practitioners
In March 2009, the California Prenatal Screening (PNS) Program expanded to incorporate first-trimester serum analytes and nuchal translucency (NT) examination data to provide first-trimester combined screening for Down syndrome and Trisomy 18. The PNS Program accepts NT data only from NT practitioners who are actively credentialed.
Practitioners may submit their NT data online by creating a Screening Information System (SIS) account.
The program provides multiple tools to assist NT practitioners.
