A pregnancy resulting from Assisted Reproduction Techniques does not exclude the need for all the usual tests for diagnosing anomalies in the foetus. Initially, amniocentesis will only be carried out when the result of the triple test (triple screening) produces altered values. The triple-test consists of a blood test (biochemical screening) and an ultrasound which includes measuring the nuchal translucency of the foetus.
Care must be taken with women pregnant with twins because the blood analysis is not reliable and, in this case, only the ultrasound will help the gynaecologist to establish the risk.
In the case of recipients, the triple test should be carried out using the age of the donor (and not that of the recipient) and therefore, the need for an amniocentesis test will be low.
You must always follow your gynaecologist’s advice of and refer to the law in your country. The triple test and the amniocentesis test are not usually compulsory.
