If the screening test comes back positive, a diagnostic test is performed. Some diagnostics tests include Amniocentesis, CVS, and PUBS. In some of these tests fluid from the sac surrounding the child is tested, placenta material is examined, and blood from the umbilical cord is examined. After both the screening and the diagnostic tests are complete, the doctors will know if the child has Down Syndrome.
