Lab Information

The information provided below is to help laboratories understand their role in this program.

Who May Participate?

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.

What Is the Lab's Role in the Program?

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.
