• Rationale and Comments

    False-positive and false-negative results occur with cell-free DNA screening. Any positive cell-free DNA screening result should be confirmed with invasive diagnostic testing prior to a termination of pregnancy. If cell-free DNA screening is performed, adequate pretest counseling must be provided to explain the benefits and limitations.
