Chorionic villus sampling (CVS) is a type of prenatal diagnostic test to detect chromosomal problems that can result in genetic diseases and birth defects. It involves taking a small sample of part of the placenta (the chorionic villi) where it is attached to the wall of the uterus.
CVS can diagnose chromosomal abnormalities that cause conditions like Down syndrome, sickle cell anemia, cystic fibrosis, and Tay Sachs disease. It does not diagnose neural tube defects. Since the procedure examines genetic material, it can tell you the gender of the fetus.
CVS is performed earlier in pregnancy than amniocentesis. It is done between the 10th and 13th week of pregnancy (measured from your last menstrual period). It is reported to be 98% to 99% accurate in detecting genetic abnormalities. CVS can also be used to detect paternity and is 99% accurate in establishing paternity of a fetus.
Chorionic Villus Sampling - Experience Question: Please describe your experience with chorionic villus sampling.
Miscarriage A miscarriage is any pregnancy that ends spontaneously before the fetus can survive. Miscarriage usually occurs before the 13th week of pregnancy. TheDown Syndrome Down syndrome is a chromosomal disorder that results in the presence of an additional third chromosome 21, also referred to as trisomy 21. Most individualsCystic Fibrosis Cystic fibrosis is a disease of the mucus and sweat glands. Cystic fibrosis is an inherited disease. The outcome of the disease leaves the body malnourished,Sickle Cell Disease (Sickle Cell Anemia) Sickle cell anemia (sickle cell disease), a blood disease which shortens life expectancy, is cause by an inherited abnormal hemoglobin. Symptoms may includeFragile X Syndrome Fragile X syndrome is the most common inherited form of mental retardation. It's caused by a mutation on the X chromosome. People with Fragile X syndromeBirth Defects Birth defects have many causes and currently, are the leading cause of death for infants in the first year of life. Some of the causes of birth defectsTrisomy 18 Trisomy 18 is an chromosomal condition that causes severe birth defects in newborns. Many babies born with trisomy 18 do not live past one month of age.Genetic Disease Genetic disease is a disorder or condition caused by abnormalities in a person's genome. Types of genetic inheritance include single inheritance (for example,Hemophilia Hemophilia is one of a group of inherited bleeding disorders. Hemophilia A and B are inherited in an X-linked recessive genetic pattern and is more commonAchondroplasia A common form of short stature, achondroplasia (dwarfism) is a genetic condition causing a disorder of bone growth. Complications of achondroplasia thatUrine Blockage in Newborns There are many syndromes and defects that may cause urine blockage in newborns. Defects in the urinary tract that may cause urine blockage include vesicoureteral
