In Scotland 39 per cent failed the £95 test.

But the figure in Northern Ireland was HIGHER - at 42 per cent.

And the combined figure for northern and southern England outstripped both at a massive 51 per cent, more than one in two.

The samples are collected via mouth swabs from father, mother and child, and analysed in fully-accredited laboratories.

Nichola McChrystal, founder and scientific director at BioClinics Group, said: “The statistics are within the realms of what I would expect, due to the fact that I have worked in this industry for well over a decade.

"I would imagine that they would appear shocking to the general public.

"However, it is important to understand that the families approaching BioClinics for answers generally have good reasons for raising the question of paternity.

"The statistics should not be considered as a representation of similar matters for the general public as a whole.

"These cases are testament to the fact that establishing paternity when a child is young is the best course of action.

"However, some tests reveal family secrets only when parents have passed away, and this can have a devastating effect on the individuals involved."
