An analysis, usually of the DNA or blood type of a mother, child, and putative father, to estimate the probability that the man is the biological father of the child.
paternity testing n.
A test to determine the father of a child. Because paternity is a clinical estimate, there is the need to have tests to determine whether it would be possible for an individual to have fathered a specific child. At one time, the tests used to prove or exclude the possibility of paternity used blood type data from the child and the suspected father. Tests involving the technique of molecular genetic fingerprinting and of determining genetic markers are available and have the ability to exclude almost all except the father. Use of these techniques makes it possible to distinguish differences between the genotype of all individuals except identical twins.
