What is NIPT (New Prenatal Diagnosis)?

NIPT (New Prenatal Diagnosis) is a test to diagnose three types of chromosomal abnormalities (21-trisomy, 18-trisomy, and 13-trisomy), commonly known as Down syndrome, by taking a small amount of blood from the mother and testing the fetal DNA (genes) contained in the blood. NIPT (New Prenatal Diagnosis) is a test with a high accuracy probability of 99% sensitivity and 99.9% specificity, and is capable of testing for negative and positive results.

The term "NIPT" for "new-type prenatal diagnosis" stands for Non-Invasive Prenatal genetic Testing, which translates to non-invasive prenatal genetic testing. The term "new prenatal diagnosis" was a fancy name given by the media, but as of 2018, it has gained some recognition.

Licensed and Unlicensed Facilities

In Japan, there are medical facilities/hospitals that can provide NIPT (new-type prenatal diagnosis), which are accredited as facilities by the Japan Medical Association, and unaccredited medical facilities/hospitals. However, the American College of Obstetricians and Gynecologists has announced guidelines stating that 'all women should be given the option of screening or confirmatory testing for chromosomal abnormalities, including NIPT, regardless of age. In Japan, in March 2018, the Japanese Society of Obstetrics and Gynecology (Nissan Women) also decided to expand the policy to general practice.

The Japan Medical Association believes that it is necessary for mothers to be fully informed about the features of prenatal testing, including what the test can and cannot tell them before the test, and the effects of a positive result, in order to "be able to think for themselves whether to take the test" and "make their own decision", based on the idea that "it is necessary for mothers to be fully informed about the features of the test, including what the test can and cannot tell them before the test, and the effects of a positive result". Therefore, it is necessary for mothers to be fully informed about the features of the test, such as "to be able to think about whether or not to take the test," "to understand what the test can and cannot tell them before the test in order to make their own decision," and "about the effects of a positive result," etc. It seems that the certification system defines medical institutions that can guarantee ongoing support, including appropriate genetic counseling and psychological care, as certified facilities. Therefore, the conditions (age and timing) and costs for receiving NIPT (new prenatal diagnosis) are high, and the situation cannot be said to be one in which those who wish to receive the test can do so freely.
