This activity is intended for healthcare providers delivering care to women and their families.
After completing this activity, the participant should be better able to:
1. Describe the limitations of genetic screening tests compared to diagnostic testing with amniocentesis or CVS
2. Counsel patients regarding the use of microarray technology in the setting of invasive prenatal testing
Estimated time to complete activity: 0.25 hours

Invasive prenatal diagnostic testing usually refers to amniocentesis (analysis of amniotic fluid cells) or chorionic villus sampling (placental cells). Prenatal healthcare providers should
Each test has advantages and disadvantages that should be discussed with each patient, with the appropriate test offered based on her concerns, needs and values
Allowing patients to select diagnostic or screening approaches for the detection of fetal aneuploidy and/or genomic changes that are consistent with their personal goals and preferences
Informing all pregnant women that diagnostic testing (CVS or amniocentesis) is an option for the detection of chromosome abnormalities and clinically significant CNVs
The cells obtained from amniocentesis or CVS are analyzed to determine if the number of chromosomes are correct (46) and whether there are structural changes such as deletions or duplications. Routine karyotyping is done using light microscopy. If changes are smaller than the resolution of a microscope, then molecular techniques are required and these small alterations are called microduplications or microdeletions (see ‘Related ObG Topics’ below). Presently, despite major advances in screening technologies, diagnosis of fetal aneuploidy still requires an invasive test.
…amniocentesis is associated with a procedure-related risk of 1:300 at most, or more likely, no significant increase in risk
With regard to CVS, our results demonstrate that, there is no significant procedure-related risk associated with undertaking this procedure
