A 35-year-old member asked:

do i have to have an amnio if the ultrasound shows lots of findings of trisomy 18?

Dr. Pam Yoder
Specializes in Maternal-Fetal Medicine
Diagnosis vs screen: Most maternal-fetal medicine or OB doctors. Sonographers spend time looking at the heart and other structures for abnormalities that can be associated with chromosomal or other problems. Details they see change with fetal age and position. Because there might be structures they cannot see, ultrasound is considered a screening test. To diagnose trisomy requires amniotic fluid or baby blood studies.
Dr. Andrew Ho

Decision making: The one and only purpose to undergo a screening or diagnostic test is to provide information that can help with making a decision. If ultrasound results already provide enough information for you to make a decision, it does not make sense to do amnio.
Dr. James Ferguson
Pediatrics 46 years experience
Depends: If the findings would determine whether the involved mother will choose to terminate or not, the reliability of the test matters. If the mom would accept a child with normal chromosomes but some identified problems, some form of definitive chromosome study is needed.Whether this is an amnio or a NIPP study is a matter of personal choice.

A 44-year-old member asked:

How can I prevent having a miscarriage as a result of amniocentesis or cvs?

Follow instructions: No matter what you do, there is always a risk of miscarriage following these procedures. Most doctors who perform them will tell you to limit your activity for 24-48 hours after the procedure. Make sure to follow all instructions you are given to minimize the risk of miscarriage.
Dr. Celia Dominguez
Fertility Medicine 34 years experience
Ask the doctor their own rates especially for cvs and no doubt the more experience a physician has the lower the risks usually in their hands.

Dr. Stephen Saponaro
Specializes in Radiology
Images of the body: Ultrasound, ct, and MRI are three different types of imaging procedures which allow the radiologist see what's going on in your body. Each modality has it's own strengths, weaknesses, and indications. The best use of each is guided by the radiologist. The radiologist interprets at the images and provides a report to your doctor.
