Intended Audience
This clinical pathology activity is intended for pathologists.

Description
Fetal aneuploidies are common, including trisomies for chromosomes 13, 18, and 21, with trisomy 21 (causative of Down syndrome) being the most frequent. In the setting of prenatal testing for genetic and congenital abnormalities, it is important to understand the differences between screening and diagnostic testing. An accurate understanding of the different techniques available for prenatal aneuploidy screening as well as the differences between screening and diagnostic aneuploidy testing will ensure that the best testing methodology is selected for each patient during pregnancy according to her unique needs and circumstances. This activity will provide a thorough understanding of the different fetal aneuploidy testing methodologies and performance characteristics and will enable pathologists to serve as expert consultants to their obstetrician colleagues.

Objectives
After completing this activity, you should be able to:

1. State the key differences between screening tests and diagnostic tests in the setting of prenatal fetal aneuploidy testing.
2. Describe the technology and clinical applications of cell-free DNA (cfDNA) screening for fetal aneuploidy (noninvasive prenatal screening (NIPS)).
3. Compare and contrast NIPS with conventional first and second trimester maternal serum screening methods and invasive testing.
4. Describe the established professional guidelines regarding options for fetal aneuploidy screening including the roles for NIPS and genetic counseling.
5. List the clinical laboratory quality assurance and quality control for cfDNA-based NIPS tests used to detect fetal aneuploidy.
