Counseling is recommended, ideally in the first trimester, prior to pursuing any type of prenatal screening or diagnostic testing. Screening tests provide risk assessment and determine whether the individual is at increased risk for having a fetus with a genetic condition. Diagnostic testing determines if the fetus is affected by a chromosomal or genetic abnormality by analyzing the fetal DNA through invasive testing. Evolving technology has made the use, interpretation, and choice of appropriate test for each individual challenging for both patients and providers.
