The information provided here is to help laboratories
understand their role in this program.
We invite laboratories who currently perform first trimester
risk assessment for fetal aneuploidy to join our program. First trimester
screening for aneuploidies includes a Nuchal Translucency scan plus a first
trimester serum sample to measure PAPP-A and either intact or free beta hCG.
Each participating laboratory plays a crucial role in the
monitoring process by providing sonographer-specific NT measurement data to
NTQR. These data are used for on-going epidemiologic monitoring to ensure that
the NT measurements submitted by providers to laboratories are
accurate.
