RESUMEN
AIM: In Japan, noninvasive prenatal testing (NIPT) has been performed by facilities accredited by the Japanese Society of Obstetrics and Gynecology since 2013. However, since 2016, with the implementation of NIPT, which can only be performed by blood sampling, non-obstetricians have been involved in prenatal testing. Therefore, in July 2022, a new government-involved NIPT certification system based on Health Sciences Council guidelines was introduced to ensure access to prenatal testing information for pregnant women. METHODS: This survey was conducted in February 2023 and was the first survey after the certification system implementation. We conducted a web-based survey of 1227 pregnant women and nursing mothers who underwent NIPT after July 2022 to evaluate their experiences. RESULTS: Respondents were categorized by certification status as certified (C: 56%), non-certified (non-C: 23%), or uncertain (Q: 20%). The C group with a higher mean age at examination (35.0 ± 4.5 years) paid lower examination fees, received longer pre- and post-examination explanations, and underwent more weekday examinations (80%) than the other groups. Most respondents, 67%, 48%, and 53% in the C, non-C, and Q groups, respectively (p < 0.0001), stated that "NIPT needs to be regulated by the government or academic societies." The non-C group was more likely to say, "Insufficient post-test explanations at the laboratory made me more anxious," than the other groups when the testing results were non-negative (p = 0.015). CONCLUSIONS: Despite government regulation, some pregnant women choose convenience over certified facilities, risking inadequate care. The government should ensure that NIPT is a safe option for all pregnant women.
