Various researchers from Massachusetts medical Society explained that there were two methods to perform the procedure. The first being transcervical, which when a catheter is placed through through the cervix, therefore it can reach the placenta to obtain the chorionic villi cells by the form of suctioning. The other method being a transabdominal, where a needle is used and pushed into the abdomen to reach the placenta and attain the required tissue needed.The researchers found that of both forms of chronic villus sampling procedure 97.8 percent cytogenetic diagnosis were made. Moreover, there were no form of error made bin the results of the sex or the specific identification of critical trisomes such as 13, 18, and 21. Therefore, concluding that the procedure is an effective technique which can be utilized to attain an early prenatal diagnosis of the
