How Reliable Are Amniocentesis Results for Diagnosing Chromosome Disorders?
How Reliable Are Amniocentesis Results for Diagnosing Chromosome Disorders?Answer: Amniocentesis is considered the most accurate and reliable prenatal test available for evaluating chromosome disorders in a fetus. According to a widely cited 1976 study, amniocentesis is 99.4% accurate for diagnosing chromosomal abnormalities. The reason why amniocentesis is so reliable is because it involves genetic analysis of cells that come directly from the baby. Amniocentesis will nearly always be accurate for predicting the baby’s gender — and only in extremely rare cases will the results of an amniocentesis provide a false positive or a false negative for the most common chromosome disorders. Note, however, that an amniocentesis does not screen for every genetic disorder that is known to exist. The amniocentesis will check the number of chromosomes and evaluate whether there are 23 pairs, thus allowing detection of
