Paternity testing

Specimen:

10 mL blood in lithium heparin or EDTA tube; smaller volumes may suffice in neonates. Specimens should be collected from mother, child and putative father(s).

Note that special collection, transfer and storage procedures apply as there may be legal implications to the procedure. Consult pathologist.

Method:

DNA polymorphism analysis of DNA derived from mother, child and putative father. See also Molecular genetics - forensics.

Application:

Determination of paternity.

Interpretation:

The number of band matchings in the DNA of the child and putative father are determined. The probability of paternity can be determined by reference to the frequency of these matchings in the general population. If necessary, the validity of the results will be determined by the Court.
