A further method of diagnosis is the prenatal test called Life Codexx
In order to carry out the test a blood sample is taken from the mother in order to find genetic material of the unborn child in that sample. A complicated method is then able to determine the risk for a trisomy 21. The result will be available after 10 to 14 days. We will only know the risk for trisomy and cannot determine whether your child really has the disorder.
The test is meant for patients above the age of 40 years and those with a conspicuous family history, as well as after a conspicuous first trimester screening.
The idea is to avoid invasive diagnostic even in a case of high risk.
The test can take place after the 12th week of pregnancy. Furthermore, a precondition is that you are only pregnant with one child (not twins, for example).
When there is an increased risk, but the ultrasound does not show any indications and, therefore, one does not want to undergo an invasive therapy, the test makes sense.
The test is a new invention. That is why there are few experiences (concerning the results) so far. The reliability of the test is at 95%; 2–3% of the tests do not provide any result. A conspicuous result will be cleared up by an amniocentesis.
The prenatal test will not be paid by the statutory health insurance.
