What is The Difference Between a Home Paternity Test and a Legal Paternity Test?

Technically, there is no difference between a Home Paternity Test (aka Peace of Mind Test or Curiosity Test) and a Legal Paternity Test. The only difference lies in the way the DNA samples are collected. For a home paternity test, you can simply order a DNA sampling kit online, receive the kit at home and collect samples yourself from the comfort of your home. The DNA kit includes detailed instructions on “How to collect DNA samples” using sterile oral cotton swabs and documentation for labeling and consent of the test participants. Once the samples are collected you just send them to our laboratory for analysis and receive the results in 7-10 working days.

If you need the results of a paternity DNA test to be used in a legal context, Canadian Forensics Inc (CFI) offers Legal DNA Testing Service that ensures the admissibility of the DNA test results in court. For Legal Paternity DNA Tests, samples are collected following a strict chain of custody. Test participants must book an appointment with CFI and samples will be collected by a nurse to ensure the positive identification of the test participants. The results of a legal paternity test do not differ from that of a peace of mind (curiosity) paternity test and should be the same.

Frequently Asked Questions – Legal DNA Testing

No, for legal paternity DNA testing a strict chain of custody must be followed to make the test results court admissible. Chain of custody outlines when, where and how a DNA sample was collected and handled  (starting from the moment the DNA sample was collected and ending with the disposition of the sample). A continuous and complete chain of custody ensures the identity and integrity of the DNA sample. For home paternity test, there is no way of tracking the origin and handling of the DNA sample thereof chain of custody is not maintained.

Mother’s participation in the DNA test is optional. Although mother’s participation is recommended, it’s not required. A child inherits 50% of its DNA from the biological father and 50% from the biological mother. By comparing the mother’s DNA profile with that of a child we can determine which half of the DNA profile came from the mother and which half must come from the biological father. Thus making DNA test results more conclusive. In extremely rare cases mother’s absence in the testing can produce inconclusive result.

A paternity DNA DNA test is scientifically considered to be the most accurate testing method available. In cases of “inclusion of paternity” where a man is highly likely to be the biological father with about 99.9% accuracy, or that he is excluded as being the biological father with 100% accuracy. 

Our turnaround time for home paternity tests is 7-10 workings days beginning the day we received all samples in our lab. The only exception to this time frame is for Legal DNA testing where it may take 10-14 working days for the results to be emailed to the test participants. We may require additional time to process discrete samples (samples other than swabs).

No, arrangements can be made to collect DNA samples from participants at different times. 

No, a legal DNA test collection cannot be completed without proof of identity that has to be valid, original and govt issued.
