This is an email from a customer who used our DNA Parent-Child Test.

On August 14, 2020, we received the following email from a customer in Tokyo.

Dear ****,

Thank you for your assistance.
This is ****.

Thank you for contacting me about the test results.
I am sorry to trouble you, but please let me confirm the following 2 points regarding the test results.

① Regarding the probability of paternity
On your company's website, it states that the guaranteed value for the probability of paternity is 99.9999999999% or 0%.
https://seedna.co.jp/information/99-9999999999%/

In that case, what does the 99.9999998% and 99.9999994% from this test result mean?
Is it correct to judge that it is virtually impossible to deny the blood relationship between the "alleged father" and the "child"?

② Identical twins
The website states that if the "alleged father" has an identical twin, they cannot be distinguished, but
if there is no identical twin, is it correct to understand that they can be distinguished even if there are other blood relatives?

For example, if the father's older brother were tested against the father's child, is it correct to understand that the probability of paternity would be 0%?

I am sorry to trouble you when you are busy, but I would appreciate your kind assistance.

****

◆◆◆◆Our reply◆◆◆◆

＞① Regarding the probability of paternity

We apologize for the confusing wording.
The guaranteed value for the probability of paternity in the article is the guaranteed value for the ultra-high-precision test that we perform.
The guaranteed value for a standard father-child test is a probability of paternity of 99.99%.

To explain the "99.9999998% and 99.9999994%,"
for a standard father-child test, there is a convention to list the probability of paternity down to the digit where the number is no longer a 9,
and we actually record this in our reports as well.

Please rest assured that if the probability of paternity is 99.9% or higher, it is considered by international standards to be impossible to overturn the blood relationship.


＞② Identical twins

Yes. It is just as you understand, ****.
In the case of a positive result, there is no problem unless the men considered as the alleged father are identical twins with each other.

If you have any other questions, please contact us.
Thank you very much.
