The decision to have a paternity test should not be taken lightly and you may have lots of questions. We urge you to consider all of the people involved and to decide whether this is the best course of action, particularly for any children in question. The following are the most frequent questions we get asked.

Are the results conclusive?

When a mother, child and possible father are tested Cellmark's results will either show he is not the father or normally provide proof of paternity with a confidence level of 99.99% and usually greater than 99.999%.

We also carry out other types of relationship testing, for further details please contact our Customer Service team on 08000 362522.
