[Twin Testing] \"My mother and we are all amazed by this result.\"

Thank you very much.
My mother had told me that the doctor at the hospital said they were fraternal (dizygotic) twins, so my mother and we are all amazed by this result.
Does the positive probability in the test results indicate the accuracy of the result?

Dear ** **,

Thank you for contacting us despite your busy schedule.
My name is ** from seeDNA Customer Support.

A positive probability of 99.9999998% does not mean "identical twins with a probability of 99.9999998% or higher."
The positive probability is a genetics term that indicates the reliability of the test.
If we were to interpret it as the probability of a blood relationship, it would mean "identical twins with a probability infinitely close to 100%."
Please rest assured that it is considered impossible to negate this figure.

We are truly glad that we were able to be of some help to you, **.
If you have any questions or concerns regarding DNA testing in the future, please feel free to contact us at any time.

Thank you very much for using our service on this occasion.
