Paternity Testing

What does “excluded as the biological father” mean?

2017-02-21T11:19:51+00:00

It means that the DNA profile of the alleged father does not match the DNA profile of the child. Therefore the result is consistent with the tested man not being the biological father of the child.

What does “not excluded as the biological father” mean?

2017-03-21T14:41:29+00:00

It means that the DNA profile of the alleged father matches the DNA profile of the child. Therefore the result is consistent with the tested man being the biological father of the child.

What does “probability of paternity” mean?

2017-02-21T11:17:21+00:00

This is the probability, expressed as a percentage, that the tested man is the father of the child rather than an unrelated, untested man of similar ethnic origin being the father of the child.

What is the Paternity Index (PI)?

2017-02-21T11:17:42+00:00

The paternity index is the likelihood that a piece of DNA, known as an allele, at a given genetic marker was passed to the child by the alleged father rather than by an unrelated, untested man of similar ethnic origin.

Who will receive the test results?

2017-02-21T11:02:20+00:00

The results will be given to the person nominated on the consent form and other authorised persons where appropriate. Please refer to our Code of Practice for more details.

What is the Combined Paternity Index (CPI)?

2017-02-21T11:17:53+00:00

The combined paternity index is the likelihood that the alleged father is the biological father of the child rather than an unrelated, untested man of similar ethnic origin. The CPI is calculated by multiplying the PIs for each tested genetic marker.

Why do we need to know about ethnic origin?

2017-02-21T11:18:11+00:00

The alleles shared by the alleged father and child occur with different frequencies in people of different ethnic backgrounds. For example, some alleles are common in Chinese individuals but are less common in white European individuals and vice versa. Calculations of PI, CPI and probability of paternity depend on how common or rare the alleles [...]
