A method of sampling chorionic placenta-tissue from which placenta will be formed, which has the same genetic structure as the foetus. This method is controlled via ultrasound – through pregnant belly and at any moment you can see where are the foetus and placenta-tissue from which the sample is taken. It is done during the 10-14 week period.
This is the recommended method for the invasive diagnosis of genetic anomalies, as it is performed early on in the pregnancy, yielding results quickly and with a low chance of complications. This enables the mother to be certain her foetus is genetically healthy, or make choices earlier on should the results be unfavourable.
