I would like to know whether this result could ever change in the future.

Thank you for your continued support.
As for the test result, the paternity probability was 0%,
and I was informed that the man tested is not the biological father.
I would like to know the reasoning behind why this conclusion is considered accurate.
The result itself was actually a welcome one, and I will continue on with my pregnancy, but I still cannot quite believe this result and feel anxious about it.
I would like to know whether it is okay to trust this result,
and also whether this result could ever change in the future.

Thank you for contacting us.

Regarding your inquiry,
the detailed data for this test is as stated in the result report.
Where there is no genetic inconsistency between father and child, the result is marked "+"; where there is a genetic inconsistency, it is marked "−".
If there is a biological parent-child relationship between father and child, there will be no genetic inconsistencies at all, and the result column will show only "+" marks.

In theory, in a paternity test, if even a single "−" is present, the parent-child relationship is considered to not exist.
Typically, however, a lack of biological parent-child relationship is confirmed based on inconsistencies found at multiple locations, around a dozen or more.

This result is unrelated to the birth or growth of the child and will never change over a lifetime.
Furthermore, even if a paternity test is carried out again after the child is born, the result of the paternity test will not be overturned.

That is all for now.

If you have any further questions, please feel free to contact us.
Thank you very much.
