Obstetrics care at Northwestern in Chicago may include specific DNA testing

Dr. Stanley Friedell, Northwestern Women's Health Associates S.C Providing Obstetrics care at Northwestern in Chicago may include specific DNA testing

Confirmation of a pregnancy can be extremely exciting. Learning that the pregnancy is considered “risky,” however, can cause parents-to-be stressed. At Northwestern Women’s Health Associates , we provide compassionate, skilled care that may include specific testing in certain situations.

When we may test for chromosomal abnormalities

Chromosomal abnormalities are not a concern that parents have any control over; they can neither cause them nor prevent them. At the same time, there are certain factors that have been identified as an increased risk. These include:

  • Mother is aged 35 or older
  • There is a family history of chromosomal abnormalities
  • Evidence of potential chromosomal abnormalities have been identified on prenatal ultrasound
  • The serum screening test returns an abnormal result

About chromosomal abnormalities

Chromosomes are present in every cell of the body, structures which hold our inherited genetic makeup. It is our chromosomes that dictate how we develop. In each set of chromosomes, of which most have 23, are thousands of genes.

Abnormalities occur when a baby is missing a chromosome or has an extra, known as trisomy. One of the most recognized trisomies is trisomy 21, or Down’s Syndrome. Other potential concerns include trisomy 18 and trisomy 13, both of which may produce a number of birth defects.

There are many women for whom advanced testing is a beneficial part of obstetrics care at Northwestern in Chicago. In the past, the standard of “looking a little deeper” was to gather necessary chromosomal data with invasive diagnostics such as amniocentesis or chorionic villus sampling CVS. Today, we have the means to obtain chromosomal information via a simple blood test.

Patients of Northwestern Women’s Health Associates that are at high risk may start the discussion of potential risks with a cell free DNA such as the Maternity 21 blood test. With a small blood sample, we gain precise insight into select chromosome information in a short period of time and without the risks associated with more invasive diagnostic procedures. After the MaterniT21 blood test from your Chicago OBGYN, you will have results in about one week.

Cell free DNA testing evaluates the relative amount of fetal chromosome material present in the mother’s blood. In addition to gathering data regarding chromosomes 21, 18, 13, and sex chromosomes X and Y, your health care provider may request further information. The extent of data which can be gathered by the cell free DNA blood test exceeds what is possible with any other non-invasive method.

For women that are not at high risk, we offer the first trimester screen which includes an ultrasound of the baby’s neck and a blood test at 12 weeks and a quad-screen AFP test at 16 weeks. These are often combined into a sequential screen which has a higher sensitivity and lower false positive rate.

We believe in providing the best possible care to our OBGYN patients. Our use of advanced diagnostics is just one of many reasons why Northwestern Women’s Health Associates is chosen by women from the Chicago area and well beyond. To schedule your visit with an experienced physician, call 312-440-9400.

    5 Dr. Stanley Friedell, 5 Star Review By Gerilynn H.

    Dr. Regina Belmonte has been providing all the services I have needed for over 12 years. She saw me through both of my pregnancies and her expertise is vast. Even after I moved far away from the city, I still embrace and look forward to her care and services, and I refuse to switch doctors. She is worth the trip! Going through both pregnancies I had to meet with all of the Dr's. and all were wonderful. The nurses are fantastic. I have gotten 98% of what I have ever needed just talking to a nurse. So grateful for this practice and so confident with the care I receive.

    Dr. Abbie Roth is GOLD!
    I have never met a doctor who is caring and brilliant and with a great sense of humor as doctor Abbie Roth. She is very professional and has an excellent bedside manner. When I had a life threatening complication after my C-section, she and her Prentice team of doctors and nurses were such an efficient team under pressure while making sure they explain every process and steps during the situation. Dr. Abbie Roth and her team literally saved my life! I am very fortunate to have met Dr. Roth, I will never forget her and will continue to see her for my future OB/Gyne health. I highly recommend this practice and Dr. Roth!

    If you are new to Chicago or are just looking for a new physician, please make an appointment with Dr. Friedell. This is the first time in my adult life, that a doctor spent an hour with me going over my medical history, asking questions and documenting my history accurately. His assessment and subsequent surgery were all done t a T! I wouldn't hesitate to recommend him or his staff. I have had very positive experiences every time I've gone and I always leave feeling like I've been really seen and heard.

    I was recommended to NWWH through a friend after a year of unsuccessful IUI with my partner. We were seen and cared for by Dr. Friedell. Best decision ever. You will definitely wait for the doctor for maybe 30 minutes past your appointment time but you will not regret it. His thoroughness and patience to explain everything to us in a way we understood was amazing. He was quick to start a game plan for us. We will definitely stick with Dr. Friedell as our OB/GYN.

    Apart from Dr. Friedell, the staff was quick to perform any lab work and ultrasounds with friendly conversation and compassion. This type of service really helps when we've gone through a rough time trying to get pregnant. Definitely make an appointment with Dr. Friedell.

    I have been going to Dr. Friedell for over a year now and he has been nothing less than amazing. When I first came to him to discuss pregnancy, he was incredibly informative and understanding. He was also willing to take the time to answer all of my questions and help in any way he could. He just delivered my son in March and to say he went the extra mile during delivery would be an understatement. I had some complications and with any other doctor I would have had a c-section. Dr. Friedell worked with me and was extremely patient and because of his care and expertise I had a successful vaginal delivery. I cannot recommend him highly enough!

    I have been going to this office for little over a month now due to some complications! I have been seen Dr. Friedell, he is very caring and always made sure he answers all my concerns. I am beyond impressed with my experience with Dr Friedell and his PA " Amber". Dr Friedell called me many times after hours to talk to me about my medical results and answers any concerns that I have.

    I would highly recommend Dr Friedell.

    I have been a patient of this practice for over 5 years now and have only positive reviews of Dr. Feldstein. He was the doctor on call and delivered my third son without any complications. He was knowledgeable, patient focused and went above and beyond to answer my questions and provide a safe and healthy delivery. I also want to note his positive bedside manner to not only my husband and I, but to the nursing staff that was working with him. He was very respectful and I am very thankful to have had him for my delivery. I would recommend this group, Dr. Feldstein in particular without reservation.

    I switched to Dr. Roth mid pregnancy due to health insurance reasons and it was probably the best decision I have ever made in my life. She is definitely warm and funny but also extremely competent and knowledgeable. I would say what makes her stand out from other doctors is how calm and not reactive she is in even the most dire situations. My son was in serious fetal distress (unexpected and not preventable) and she was very calm and reassuring as we literally ran to the OR for my c section. With the rise of c sections today I feel Dr. Roth is one of the few remaining fabulous ob's that truly plans for normal vaginal births (your choice if you want an epi or not) and although I needed a c section I knew it was truly necessary. I could not speak more highly of her, not only did she save my sons life but she made me feel safe, secure and empowered even when decisions and actions were out of my hands.

    I can not tell you how wonderful my experiences have been. Dr. Sharon Wise is my doctor and she is fantastic. She is straightforward and honest about treatments and procedures. I enjoy her sense of humor, and I found her bedside manner when delivering my son to be excellent.
