The quad screen is a maternal blood screening test that is similar to the First trimester screening test. Your obstetrician may choose to perform the quad screen to estimate your risk for fetal chromosomal problems, spina bifida, or open abdominal wall defects.
If your test comes back abnormal, your doctor may refer you to one of the doctors here at RPG for further evaluation. It is important to note that an abnormal quad screen test does not mean that there is definitely something wrong with your pregnancy.
We feel it is very important to remember what a screening test is before getting one performed. This will help ease some of the worry that can accompany test results. Screening tests do not look only at results from the blood test. They compare a number of different factors (including age, ethnicity, results from blood tests, etc...) and then estimate what a person’s chances (or odds) are of having an abnormality. Screening tests DO NOT diagnose a problem; they only signal that further testing should be done.
The doctors at RPG will perform a comprehensive ultrasound to evaluate your level of risk. They will discuss your option of diagnostic testing to help determine whether or not the baby has a chromosome abnormality. Many patients choose not to perform diagnostic testing for a variety of reasons. The doctors at RPG will provide you with your testing options, and be supportive of your decision.
