It is computed using a mathematical formula that considers all of the evidence in a case—both genetic evidence (Combined Paternity Index) and the non-genetic evidence (Prior Probability).

What is a high paternity index?

The Combined Paternity Index is a ratio indicating how many times more likely it is that the tested male is the biological father than a randomly-selected unrelated man with a similar ethnic background. This number varies on a case by case basis. The higher CPI number, the stronger the results.
