How much does a non invasive prenatal DNA test cost

Non-invasive DNA testing is to collect the peripheral blood of pregnant women for informatics analysis to determine the risk of fetal trisomy 21, trisomy 18, and trisomy 13. Ordinary non-invasive DNA tests mainly screen for the above three chromosomal diseases, and the price is about a few thousand, and some provinces and cities have recently carried out free tests. At present, a number of hospitals have also carried out upgraded non-invasive DNA tests, in addition to screening the above 3 diseases, 4 sex chromosome diseases, and another 93 chromosomal diseases, a total of 100 chromosomes are screened, ** in two or three thousand yuan.

Hello, the appropriate time for non-invasive prenatal genetic testing is between 12 weeks and 24 weeks of pregnancy, and it is generally possible to do Down's screening first, and then do non-invasive if there is a problem with Down's screening.

Fetal whole chromosome gene testing non-invasive chromosome 23 plus microdeletion 4m enhanced prenatal examination, only 5ml of pregnant woman's blood is needed to check the risk of fetal chromosomal abnormalities.

Compared with traditional prenatal care, only 5ml of mother's blood needs to be drawn, which does not cause any harm to the mother, and does not cause the risk of miscarriage, which is absolutely reliable.

Efficient: The test can be carried out at 12 weeks of pregnancy, more than two weeks earlier than the traditional prenatal check-up, and the report can be retrieved within 7 working days after the test, so that you can know the health status of the fetus as soon as possible, with absolute peace of mind.

Accurate: Using next-generation sequencing technology (NGS), 23 pairs of chromosomes and 20 microdeletions are detected, providing comprehensive coverage of common heterochromic abnormalities and microdeletion diseases.

Comprehensive fetal whole-chromosome screening (testing advantage).

Early stage: can be checked at 12 weeks of pregnancy;

Safety: no risk of infection, avoid fetal infection and miscarriage in uterus;

Non-invasive: 5ml of maternal arm venous blood is drawn without amniocentesis;

Comprehensive: screening of all 23 pairs of chromosomes + scanning of 20 microdeletions;

Accuracy: Dual-platform NGS next-generation sequencing technology, accuracy.

Non-invasive DNA is divided into two kinds, one is ordinary non-invasive DNA, which is formulated according to the economic level of the hospital and the region, ranging from 500-2000 yuan, and even some local hospitals have provided free testing items if they can have their own machine testing.

In addition, a type of non-invasive DNA is called non-invasive DNA+, which detects more than a dozen other micro-duplication microdeletion syndromes in addition to routine testing and chromosome 21. Due to the increase in testing items, the cost is relatively more, and the cost of non-invasive DNA + should be between 2000-3000 yuan, so the cost of non-invasive DNA mainly depends on the local medical level and economic level.

Between 12 and 26 weeks of gestation, non-invasive prenatal DNA testing should be done as soon as possible.

If the amount of free fetal DNA in the peripheral blood (venous blood) of the pregnant woman is less than 12 weeks gestation, the amount of free fetal DNA may be insufficient and a new blood test may be required.

Done as early as 12 to 26 weeks of gestation, this allows for a longer and earlier diagnosis in case of a positive result for a genetic disorder intervention window.

In case it exceeds 26 weeks of pregnancy, it is also recommended to do it in time, so as to be ready for the early detection of genetic diseases, such as **** earlier.

The fee is approximately

Ordinary version (all aneuploidy genetic diseases): about 2400 yuan.

Upgraded version (all aneuploidy genetic diseases + chromosomal microdeletions + microduplication syndromes): about 3200 yuan.

And there is no one who is good or bad, you need to choose according to the situation. The cost here is only a reference standard, and it may vary from one testing institution to another, but neither the institution nor the user should pursue a very low fee.
