Q. What does an increased risk chromosome result mean for me?
A. Most of these test results are associated with normal pregnancies. In some pregnancies, these test results are associated with a baby having a chromosome abnormality.

Q. Should I have a second blood test?
A. No. If the first MSAFP/free BETA test result shows an increased chromosome risk, a second blood test is not recommended because clinical research has proven that a second test is not accurate.

Q. Does the test result mean that my baby definitely has a chromosome abnormality or a birth defect?
A. No. The blood test is not a conclusive diagnostic test. It is a screening test which identifies women who should be offered further tests because they have a risk greater than that of a 35 year old woman of carrying a baby with a chromosome abnormality. However, it is important to know that other factors can also cause this test result in the mother’s blood.

Q. What can cause this test result in my blood?
A. The majority of women with these test results are carrying normal babies. 1) Many women are just not as far along in their pregnancy as originally thought. 2) A less likely cause is a chromosome abnormality in the baby.

Q. If the dating of my pregnancy is correct, how can I learn what is causing this test result?
A. Your doctor will offer you an amniocentesis which can determine whether your baby does or does not have a chromosome abnormality./ Amniocentesis has been proven to be very safe and very accurate.

Q. Do these blood tests detect all possible birth defects and mental retardation?
A. No. A general blood test that can detect all birth defects and mental retardation is not available. The MSAFP/freeBeta tests detect some but not all babies with a chromosome abnormality.
