This shocked me initially until I read the article and then thought this through. It is almost obvious that it would be a high percentage that are proven not to be the real father.
After all, I assume you only take a test if you have a doubt so therefore if the doubt is enough to take a test the chance of the fathers baby not being you the test taker is probably high.
ALMOST half of UK men who take a paternity test turn out not to be the real father, new figures show. Testing firm DNA Clinics, which is part of the Salford-based BioClinics Group, analysed the results of 5,000 tests selected randomly from those it conducted for clients between January 2014 and June 2016.
