Amniocentesis and fetoscopy are two of several modalities used to offer information during the prenatal period of the status of the fetus. Amniocentesis is most frequently used and with continuing research is becoming an invaluable aid to prenatal diagnosis. With the recent studies of DNA characteristics of globin chains of cells obtained at amniocentesis, the need to obtain blood directly from fetal vessels to diagnose major hemoglobinopathies prenatally is rapidly diminishing. Open neural tube defects are diagnosable with alpha feto protein analysis. All chromosomal defects are accurately quantitated and more than 100 inborn errors of metabolism are predictable. Fetoscopy is a technique which has a limited utility. It should be confined to major centers where adequate midtrimester abortions are done in order to provide training for those who aspire to pursue this method. With fetal blood sampling the following conditions are detected: beta thalassemia major, Hemophilia A, sickle cell anemia, chronic granulomatous disease, galactosemia and Tay Sachs disease, all of which may be diagnosed directly. Alpha and beta thalassemia, Hemophilia B and homozygous Von Willenbrand's disease may be excluded. With fetal biopsy one can diagnose congenital bullous ichthyosiform erythroderma ichthyosis. During the last ten years the amount of information brought to our attention has also brought the expectation that the next decade will be the most fruitful period in our history in this discipline.
