It may seem like a silly idea to collect a DNA sample from mom for a DNA Paternity Test because there’s no doubt she’s mom, right? However, her DNA contains valuable information that can help strengthen the results of your paternity test or other tests to establish grandparent or sibling relationships.
Think of it this way: Both mom and dad give the child half of the child’s DNA. So if we test mom we can determine which half she contributed and which half came from dad.
In some rare cases, having the mother’s information along with the dad’s can mean the difference between an inconclusive DNA test result and a conclusive one. This is why we say her sample is highly recommended but not required. Most DNA paternity tests can be done conclusively without the mother’s samples.

I would like to know how you {Identigene} can legally, and morally call a mismatch, between an alleged father and child in a motherless test, an “alleged” mutation? There are several peoples lives, finances, and futures that are involved! Not too mention the so-called mutation stepped down twice making it so extremely rare to be a mutation its basically unheard of! James Watson, you may have heard of him, clearly states that whatever repeats are left after the mothers are subtracted belong to the father whomever he may be. If there are any {one or more} repeats that do not match the alleged father, HE MUST BE EXCLUDED! In my case it should’ve at MOST been inconclusive! Oh I forgot, that would mean that I wouldn’t have to pay for the test and we cant have that! You Geneticists have yacht, vacation home, luxury vacation, mistress, etc… payments that need to be made. Kids going to Harvard, wife in drug rehab, plastic surgery bills piling up, so why should I expect accurate results?! My bad!

Chris,
I am unfamiliar with your specific test (as I do not have access to test results or customer files) but I am happy to copy and paste your comment and send to our lab directors for response. I would expect a response by tomorrow. The laboratory is in Utah so it is approximately 4:30 p.m. there. I will be in touch with you soon. Thank you for your comment. We agree that paternity answers are life-changing and we approach each test very seriously and we think you should expect accurate results from our laboratory.

I bet you wont have the guts to reply! Im just an average intelligence man who has spent hundreds of hours researching everything about pregnancy and paternity testing and cant believe the BULLCRAP ive uncovered! Also Bayes Theorem is a total JOKE! Assumptions are the MOTHER to each and every SCREW-UP!

Chris,
Please let us know how we can help you. Thanks. IDENTIGENE

Dear Chris,
Our lab director responded to your question. “In any motherless test with a single 2-off mismatch, it is our policy to always run an extended panel, in order to report all available markers. If we don’t find additional mismatches, we always ask for the mother. If they refuse to send her, then and only then, do we report the result as it stands. The CPI value is as reported. If it is over 100, then it is considered conclusive evidence, however, we always include the footnote regarding the fact that a single mismatch exists and if there is another alleged father who is related to the tested man, that he should be tested. Per the guidelines established by the accrediting body for legal testing, we cannot exclude a relationship based on a single genetic marker. Since we follow the same guidelines for our personal tests, we have to report the results as they stand. Since I cannot see the actual report, I do not know if this is truly a 2-step mutation. Also, if your case is truly as you claim, we advise you to proceed with a legally collected test and get a court order to require the mother’s participation.” Hope this clarifies our testing procedures. Thank you for contacting us.
