The company has already received about 160 inquiries, the spokesperson said.
The company currently has no intention to conduct genetic counseling, with the spokesperson saying only, "We'll recommend that pregnant women speak to counselors."
Meanwhile, another company in Tokyo has promoted its prenatal diagnosis to medical institutions. In mid-March, the company sent out postcards advertising such a service to obstetric facilities nationwide.
In the postcards, the service was advertised as "the nation's lowest price and best quality." The testing fees begin from about 150,000 yen, excluding shipping charges.
The company said its test service could detect a different type of chromosomal disease that is not subject to prenatal test guidelines set by the JSOG.
Meanwhile, the company's website calls on medical institutions to provide genetic counseling and comply with guidelines of the Japanese Association of Medical Sciences, which stipulate that the views of the JSOG should be observed.
On March 22, the Japan Association of Obstetricians and Gynecologists, a separate organization of doctors concerned, sent a notice calling on its members not to use such services.
The JSOG also posted on its website a message asking for cooperation with its guidelines.
