The rest of the summary describes the evidence in more detail. Note: The Overview section summarizes the published evidence on this topic. Screening With the Pap Test and the HPV DNA Test (Cotesting): Harms.Screening With the Pap Test and the HPV DNA Test (Cotesting): Benefits.Screening With the Human Papillomavirus (HPV) DNA Test: Benefits.Screening With the Papanicolaou (Pap) Test: Benefits.Our goal is to provide you with the information you need to feel confident about your decisions and your pregnancy. They will explain various screening and testing options, recommend the tests which best suit your needs and help coordinate the recommended genetic testing. Our providers can review your family, medical and pregnancy history and help determine any risk factors for birth defects or genetic conditions that may affect your pregnancy. Contact us as early as possible so that we may determine what type of genetic testing is appropriate for you. Preconception and prenatal testing are available for many hereditary disorders. If a family member has a genetic condition, you may have reason to be concerned about passing the same condition on to your fetus. Optional expanded carrier screenings can test for a wide range of recessive genetic disorders. Our providers will meet with you and recommend which tests you should consider based on ethnicity and other factors. Some genetic disorders occur more frequently within certain ethnic groups, and carrier screening is available for many of these conditions. These parents are carriers of recessive genetic diseases that can be inherited by their fetus. Cystic fibrosis, spinal muscular atrophy sickle cell anemia and Tay-Sachs disease can occur when both parents carry the same abnormal gene, but do not have the disease themselves. ![]() Sometimes perfectly normal parents can have a fetus with genetic disorders. The test may predict the fetal gender but is not 100% accurate. This test measures the amount of DNA from specific chromosomes and can detect chromosome-related problems. Analysis of Fetal DNA in Maternal Bloodįetal DNA can be examined in a maternal blood sample after 10 weeks gestation. If an increased risk for a chromosome abnormality is revealed, diagnostic testing will be offered. Performed between 11 and 13.6 weeks, first trimester screening combines an ultrasound and a blood test to calculate the chance for chromosome-related conditions. The risk for disorders, such as Down syndrome, are more frequent as mothers get older however, there is some risk involved in every pregnancy. Diagnostic genetic testing options include chorionic villus sampling (CVS) and amniocentesis. However, it is important for parents to remember that screening tests cannot determine whether a fetus is affected with a condition, only that a pregnancy may be at higher risk.ĭiagnostic testing, on the other hand, can determine if a fetus has a specific condition. Screening tests are helpful ways to determine if a pregnancy is at higher risk for certain conditions. What's the Difference Between Screening and Diagnostic Genetic Testing? It is important for parents to remember that no test can guarantee the birth of a healthy baby. Some, but not all of these, can be detected before birth through various types of genetic screening or testing. However, every pregnancy carries some chance of a fetus having a birth defect or genetic condition. ![]() More than 95 percent of pregnancies end with a normal, healthy outcome.
