Prenatal DNA Testing

The Conclusive Results Of Prenatal DNA Testing.

The most effective way to determine the father of an unborn baby is to agree to prenatal DNA testing. Most prenatal DNA testing companies guarantee 99.9 % accuracy in determining that the alleged father is actually the father. prenatal DNA testing may be done at home if the results are only for personal use, but it is usually not recommended. If the results are needed for legal purposes the prenatal DNA testing must be done by a doctor. In order to get accurate results from prenatal DNA testing, the mother and the alleged father must be tested, so the laboratory can indentify the mothers DNA, as well as the babys DNA.prenatal DNA testing is done in different ways depending on the stage of pregnancy.

Sometime during the 10th to 13th week, a small sample of the membrane that surrounds the fetus is taken either through the abdominal wall, or through the vagina. This prenatal DNA testing procedure is called Chorionic Villi Sampling. The other method, amniocentesis, can also be performed during the 14th to 24th week. This procedure takes a sample of the amniotic fluid, which is in the sac that surrounds the fetus. Amniotic fluid contains the cells needed to analyze the DNA. In order to perform prenatal DNA testing using this method, a needle is inserted in the abdominal wall so the fluid can be extracted.

Bothe procedures will also identify any health issues or birth defects that may be developing as the fetus grows. These prenatal DNA testing procedures are considered invasive, so there is a slight risk of infection or miscarriage associated with them. Its a good idea to do research and seek advice before these procedures are performed.A non-invasive procedure is used to collect samples from the mother and father. A cotton swab picks up loose cheek cells on the inside of the mouth and the doctor then submits all the samples to the laboratory for analysis. The test results are usually returned within five business days.
