Paternity fraud is becoming a very serious issue and the figures that are emerging are frightening. In some areas it could be as high as 40%and in the others around 10%. This days more and more fathers are turning to growing number of companies offering DNA test (accurate to 99.99%) after divorce/separation due to the fact that, up to seventy percent were due to their partners adultery (even though seven out of ten divorce proceedings are started by women). Part of the problem, apparently, is the mothers are seeking “best DNA” to father their children while USING their husbands as nothing more that a reliable providers (read cash cows). However most of the cases seem to be down to pure adultery without the regards to the hurt caused or the consequences and often trying to cover the facts by pretending that the child is their husbands/partners.

Research on paternity using blood group analysis has found varying levels of 'paternity fraud'.  In some samples it is as high as thirty percent, but not all. It all depends upon the demographics of the sample (race, class, married/unmarried etc).  At the lowest end it is only a few percent, but an average of around 10% is not an

unreasonable assertion. Remember that using blood groups will only find out those cases where the blood group of the  real father and tricked father are different and the child inherits the real father's blood group.

Apart from the legal question of fraud this issue has huge implications, not only for CSA and the psychological damage caused to the fathers who honestly believed that they were biological parents but for life threatening situations, such as bone marrow extraction where the genetic "fit" must be perfect and for organ donation too, e.g. kidney.
