Chorionic Villus Sampling is a medical investigation used for diagnostic tests or as a means of sample collection for a prenatal paternity test. The test can be performed between the 10-12th week of pregnancy (slightly earlier than amniocentesis) and involves the insertion of a needle through the vagina in order to withdraw a sample of chorionic villi. Chorionic villi are structures which line the placenta in order to increase surface area and maximize contact with the mother’s blood. The test carries certain risks including miscarriage, infection or leakage of amniotic fluid. The Sample collected is rich in fetal DNA which can be used for a prenatal paternity test. The risks do however, discourage some from undertaking this sampling to establish paternity. Today, non invasive prenatal paternity tests are available which can be done with a simple medical blood draw which means chorionic villus sampling can be avoided to determine paternity.

This type of medical investigation may be used to determine whether the unborn baby is suffering with genetic or chromosomal conditions. Such conditions include: ‘Downs Syndrome’, ‘Cystic Fibrosis’, ‘Tay-Sachs’ and so on. Risks of developing these conditions increase when the mother is over 35 years of age, or if there is a known genetic condition inherited within the family.

Non-invasive methods such as our prenatal paternity tests can be performed in order to avoid going through such a risky procedure such as chorionic villus sampling, or amniocentesis for that matter. As mentioned above, our prenatal paternity testing may be safer option that still offers accurate results. Our tests are 100% safe and almost 100% accurate.

By getting more information about the unborn baby’s health you are able to make the necessary arrangements in anticipation for the baby’s birth. However understanding the risks of knowing the results must be dealt with in an appropriate manner. Getting in touch with a medical practitioner for more information or psychological care is recommended. If you want to know more about our non-invasive prenatal paternity tests, contact us today.
