Maternity/Paternity Cases

Collection Process

We routinely use buccal swabs to obtain DNA for testing. The inside of an individual's cheek is swabbed to obtain buccal cells. This process is a painless, non-invasive collection procedure. The DNA is then extracted from these cells and used for testing. If necessary, we test blood, umbilical cord blood and other types of body tissues which might have been collected at autopsy.

At the time of collection, clients are required to provide identification and also complete a Genetic Authorization Form. A strict chain of custody for all samples is maintained in order for results to be admissible in a court of law. For this reason, we cannot accept samples which are collected by the involved parties themselves, but will assist in locating a reliable collection site.

Testing Process

For a paternity case, we normally test the mother, child and alleged father. Our laboratory is able to provide results with a high level of certainty even when key family members are unavailable . In cases where one of the parents is deceased or physically unavailable, the analysis may still be performed by testing the parents of the missing individual.

Our laboratory specialists have extensive experience in the utilization and application of STR testing and are always available to answer questions

Short tandem repeats (STR), are short sequences of DNA that are repeated. Most of our DNA is identical to DNA of others. However, there are inherited regions of DNA that vary in each individual. Variations in DNA sequence between individuals are called "polymorphisms". The polymorphisms in STRs are due to the different number of copies of the repeat DNA that occur. By analyzing the polymorphic region of a child's DNA, we can establish which alleles were inherited from both their mother and father. STR analysis provides a basis to either exclude a tested man with 100% certainty or to include a tested man with 99% or greater certainty in a paternity case.


The final reports will be provided via fax or mail, to all adults and/or their representatives in a case. To ensure confidentiality, no results or details of any case will be discussed with any persons who are unable to provide suitable proof of their identities. Genetic reports are legal documents, and are admissible in the court of law. Our Staff are available for confidential interpretation of test results. Our laboratory experts have provided testimony in the court of law, and are available as expert witnesses upon request. Reports will be processed 2 to 3 weeks from the date we receive all samples involved in the case.
