Frequently Asked Questions

The test uses a non-invasive method, making it completely safe for both the mother and the baby, with no risk of miscarriage.

Non-invasive prenatal testing is completely safe and poses no risk to the mother or fetus. Unlike invasive procedures, it does not disturb the safe environment of the womb. Invasive prenatal tests, such as amniocentesis or chorionic villus sampling, involve collecting fetal DNA and carry a risk of miscarriage.

To perform the test, we require one blood sample and two buccal swabs from the pregnant mother, and two buccal swabs from the alleged father. DNA can also be collected from alternative samples from the father.

Blood samples and buccal swabs from the mother and buccal swabs from the father do not need to be collected at the same location. However, it is important to collect all samples on the same day whenever possible and send them to the laboratory as quickly as possible. This is to prevent DNA degradation and to maintain the samples in a usable condition. It is recommended that DNA extraction be performed within one week after blood collection.

Yes, a reference sample from the alleged father is required to determine if there is a DNA match with the fetus.

The blood sample from the pregnant mother must be collected by a medical facility or professional authorized to safely draw blood. We partner with over 100 clinics across Japan where blood samples can be collected.

Buccal swab samples from the mother and the alleged father can be easily collected by yourself. It is important to collect these samples on the same day as the blood draw and send all samples to the laboratory immediately. This helps maintain the quality of the received samples.
