Notes Patient Prep: This test requires a nuchal translucency (NT) measurement that has been performed by a certified ultrasonographer. The unltrasonographer MUST be certified to perform NT measurements by one of the following agencies: FASTER trial, Fetal Medicine Foundation (FMF) or Nuchal Translucency Quality Review (NTQR). To avoid possible test delays for an ultrasonographer that is new to our database, please contact the genetic counselor at 800-242-2787 extension 2020 prior to sending specimen. If an NT is unobtainable, order Maternal Serum Screening, Integrated, which can be interpreted without an NT value.
