Obstetrics Prenatal Testing Testing is done during pregnancy in order to determine if you or your baby are at risk of certain problems.  There are a number of screening tests that are done on all pregnant women and others done based on your personal history. Blood type and antibody screening, blood count, Rubella, Hepatitis B, Syphilis, urine culture and HIV testing are done routinely on all pregnant women at the first prenatal visit.  HIV testing is repeated in the third trimester per New Jersey law. Genetic blood testing is offered to determine if your baby is at risk for certain inherited birth defects.  All women are offered testing for Cystic Fibrosis.  Fragile X and SMA are additional tests offered on the basis of family history or patient request. Patients of Eastern European Jewish (Ashkenazi) descent have a higher risk of certain diseases.  Testing is offered for Tay-Sachs,  Canavans , mucolipidosis IV, Niemann-Pick disease type A, Familial dysautonomia, Fanconi anemia group C, Bloom syndrome, Glycogen storage disease type 1a, Maple syrup urine disease and Guacher disease.  Information on all these diseases will be provided at your visit or are available at:  www.geneticstesting.com/paient_info/jewish_diseases.htm Screening for Down’s syndrome, trisomy 18 and neural tube defects is offered to all pregnant women.  The risk of Down’s syndrome increases with maternal age, but is present with every pregnancy.  There are several ways of testing for Down’s syndrome.  Sequential screening involves blood testing along with ultrasound at 12 weeks followed by additional blood work at 16 weeks.  Quad screening is done with blood work only at 16 weeks and does not detect as many cases.  In women who want to be 1oo% sure that their baby is not affected, or are at increased risk, CVS or amniocentesis is available.  Screening for gestational diabetes is done at approximately 28 weeks of pregnancy.  This may be done earlier in patients with a personal or family history of diabetes or in those with additional risk factors. Group B Strep testing is done at 35-37 weeks of pregnancy in all pregnant patients.  GBS is a bacteria detected vaginally and rectally in approximately 25 % of women that can cause complications if present during labor and delivery.  For this reason, women who are positive at the end of pregnancy are treated with antibiotics during labor.
