What will the thatDNAcompany® paternity report say?

The original report is uploaded as a .pdf to a secure web-link which is provided to the person who ordered the test. The reports are in a standardised format, which complies with relevant legislation* and either excludes the alleged father or provides evidence that he is indeed the tested child’s biological parent.

If the thatDNAcompany® paternity test is negative (that is, the tested male is not the child’s alleged biological father), the report will say:

‘Based on the analysis of 23 independent autosomal DNA markers, Mr John Smith has been excluded as the biological alleged father of Teresa Green because greater than two of Mr John Smith’s DNA components are absent from the DNA profile of Teresa Green. In summary, Mr John Smith is not the biological alleged father of the child, Teresa Green’.

If the “That DNA Company” paternity test is positive (that is, the tested male is likely to be the alleged father), the report will say:

‘The probability of paternity is 99.99xxx% (assuming equal prior odds) based on the analysis of 23 independent DNA markers. Hence the alleged father, Mr John Smith, cannot be excluded as the biological alleged father of Teresa Green.
The DNA results are ‘X’** times more likely if Mr John Smith rather than an unrelated male is the biological father of Teresa Green. In summary it is more than 99% likely that the alleged father Mr John Smith, is the biological father of Teresa Green’.

We do not issue the original data (DNA profiles), since interpretation of these data is highly complex and requires a trained operative.
