Down accurate answer but it is a risky procedure.

Down Syndrome is a genetic condition which can be diagnosed by either a screening or a diagnostic at the prenatal stage. The screening test is the safest process, it does not give the certain answer but presents a result if the fetus has a greater chance of Down Syndrome. Verus the diagnostic test which gives the most accurate answer but it is a risky procedure. The screening process is a blood test and ultrasound during the first trimester, during the second trimester it is solely a blood test. Or both the first and second trimester tests can be done. During the first and second trimester both a blood test is taken to monitor certain protein levels that can be an indication of Down Syndrome. The ultrasound is done to check the fluid behind the fetus head which can again be a sign of Down Syndrome. During the diagnostic screening, the practitioner may use the process of amniocentesis, chorionic villus sampling, or percutaneous umbilical sampling which all take certain samples to test for an extra chromosome. Another method to diagnose Down Syndrome is to complete a chromosomal test of the maternal blood.    Individuals who are diagnosed with Down Syndrome do not always hold the same emotional characteristics and features or even intellectual levels. Although, those who have Down Syndrome do typically hold similar physical traits such as; short necks, flattened head, short height, and palpebral fissures. Developmental stages of communication, dealing with numbers, and problem-solving are acquired a slower rate than what is considered normal. Both children and adults with Down Syndrome tend to learn better with visual information versus verbal. Once it begins to develop social skills tend to be quite normal while memorization can be affected.      After a woman reaches the age of 35 the chances of her giving birth to a child who has Down Syndrome is increased. Although down syndrome is not typically passed down from genetics both the mother and father can pass the genetic translocation. Also, have one child with Down Syndrome can increase the chance of the second child to born with it as well.      Over the years the life expectancy for children and adults has increased with the advancement of medical science. It is normal for someone with Down Syndrome to live beyond 50 years old.
