FETAL DNA TEST

FETAL DNA TEST (NIFTY – NIPT)

We could only look at the chromosomes of the unborn baby through procedures such as amniocentesis, cordocentesis or chorionic villus sampling, and unfortunately, these procedures were risky for the baby.

We have known for many years that fetal cells circulate in the blood of pregnant women. At that time, our dream was to separate these cells in the mother’s blood and reach the baby’s chromosomes, but the technology to do this had not yet been developed.

Fortunately, this technology has developed in the last few years and we can look at the chromosomes of the baby in the womb and we can do this with a tube of blood taken from the mother’s arm. That blood contains the baby’s chromosome particles mixed with the mother’s blood and are examined. Results come 10 days after blood collection with a 99.5% success rate. Unfortunately, under these circumstances, it still cannot give 100% results, but it is still a very comforting rate. The medical algorithm suggests this to us. If the result of the double screening test is 1/1000 or above, tell the family about the test, let them know the risks. If it is 1/300 or below, recommend amniocentesis, chorionic villus sampling or cordocentesis to the family, which gives 100% results. If the result is between 1/300-1/1000, recommend fetal cell DNA in maternal blood (NIPT – NIFTY) to the patient.

If over time this test becomes effective with a 100% chance of success, then amniocentesis will be performed in very limited cases.

The disadvantage of Fetal DNA Test is that it is expensive. Prices vary due to the number of diseases it treats and the difference between companies.

Sometimes the family can be very worried. If she is pregnant at an advanced age or has a chromosomal disorder in her personal or family history, she can have the NIFTY test voluntarily without having the dual screening test. Fetal DNA test can be performed after the 10th week of pregnancy to ensure that the fetal fraction rate is sufficient.

NIFTY test, which looks at 70 chromosome diseases, is performed in our center.
