What is Early NIPT?
Until now, Hiro Clinic has conducted NIPT testing after 10 weeks, when there are worldwide publications and the validity of the test is guaranteed. This time, we randomly conducted the test on pregnant women whose pregnancies were detected at less than 10 weeks at the Tokyo Sanitary Laboratory, which conducts the test at our clinic, without checking the number of weeks, and we were able to obtain test results in all pregnant women.
NIPT testing has been recommended after 10 weeks, when a sufficient amount of foetal fraction (FF) in maternal blood is considered to be detected. The latest clinical experiment at the Tokyo Sanitary Laboratory has proved that a sufficient amount of foetal fraction (FF) can be detected in maternal blood even at less than 10 weeks.
Early NIPT is performed in pregnant women under 10 weeks, and is not restricted to the number of weeks of gestation. However, to ensure the accuracy of the test, testing after 10 weeks is strongly recommended.
A second examination after 10 weeks of pregnancy is available at no extra cost.
※Tests taken at less than 10 weeks are expected to have lower sensitivity and specificity than those taken at 10 weeks or later.
※If the Early NIPT test is positive at less than 10 weeks, there is no positive target rate or positive score reported.
Early NIPT is available for all plans except the N-Advance FM+ and N-Advance GM+ plans.
