At-Home Versus Legal DNA Tests - What’s The Difference?

So, here it is, that huge important rulebook we’ve been talking about. Let’s get into it.Whilst the tests performed at home are no different to the legally permissible models, it’s the way they are conducted that differentiates and is important.

Otherwise referred to as ‘chain-of-custody’ tests, they are valid and defensible for use in court cases regarding child support, visitation, custody and adoption within any Superior Court in the United States.

Likewise, they can also be accepted as proof of paternity by other governmental agencies, for instance by the IRS for the sake of tax or via the Social Security Administration so that they might deliver survivor benefits to a widow or widower. 

If you opt to perform an at-home test by yourself, this can not be used in a legal setting, nor can it be altered or upgraded to a legal test in the future. The samples collected do not meet the chain-of-custody requirements.

Attaining a legally admissible test requires several steps, which we’ll walk through now. If any of these steps are performed incorrectly or skipped, it’s likely that the courts will reject your DNA sample, so pay close attention!

Step One - Collecting Your Sample

First things first, a genuinely independent and third party professional must be present to take the sample for you. Likewise, said professional must be able to verify the identity of yourself or whoever is being tested, with a legitimate form of ID.

In certain states, you may be able to hire an independent third party to watch you collect the sample using an at-home kit and appropriately transfer it to the legally approved or appointed laboratory, but this depends where you live!

Step Two - Sending The Sample To A Lab

Following the collection of your sample, a second third-party approved by the courts must then ensure that it is securely and correctly shipped to the lab where the testing is performed, the part of the process specifically referred to as chain of custody.

The court in question will carefully observe the chain of custody process in order to determine whether or not the sample was collected, transferred and received by the lab by an appropriate third party at every single stage.

Step Three - The Big Test

This is the part of the DNA testing procedure you truly have no part in, besides verifying with the judge of your case or legal counsel that the organisation (or person) coming to collect, transport and test your sample will be admissible.

This is where accreditation is very important: without those all important certifications from the appropriate DNA testing authorities, it’s highly unlikely that any court would accept their test as legally admissible evidence.

Step Four - Results And Ruling In The Courtroom

Last but not least, the test must be properly submitted to the court, following the correct channels. If the results are sent directly to you, you must provide the court with all of the paperwork you received.

It’s likely that a scan, photograph or copy of the results won’t be accepted - double check with your lawyer about whether or not you need to provide the original documents in order to have them accepted.

In all circumstances, it’s usually the easiest and most likely to succeed if you can have the lab send their documentation to the court directly and provide yourself or the recipient with a second, separate copy for your records.

Top Tips For Legal Success

Always, always, ALWAYS check with the attorney you’re using, the judge of your case or a legally recognized member of the court to ensure your testing intentions are valid and will be accepted as part of your case.

Retain your DNA sample for as long as you can, at the very least until your case has been settled. It’s likely that any opposition will try to contest your results or have them re-tested, so keeping ahold of it all is in your interest.

Remember that any tampering, foul play or illegitimacy when it comes to DNA testing is an illegal offence, especially serious when engaged in a court case. Don’t even bother attempting to cheat your way to success - you will fail!

Things To Consider


Yes, it might sound a little obvious, but ensuring you opt for a DNA test that is as accurate as possible will only serve to aid your process and guarantee results you can depend on. The more genetic markers they test for, the better!

Accuracy can also be determined by the amount of accreditation a company has. This basically refers to the authority and mark of authenticity issued by an official body, to demonstrate that their standards have been met.

Turnaround Of Results

Sure, DNA testing is not a process to be rushed, but finding out the paternity of your child, for example, is not a piece of information you want to sit around and wait weeks for. Receiving your results quickly is what you want!

The majority of services will promise to have your results back to you within a couple of business days, but it’s worth checking through reviews from other customers to ascertain how accurate their turnaround times actually are.

Sample Method

Where the majority of DNA testing kits available right now utilize the classic swabbing method, which is essentially pain free and only takes a couple of seconds to achieve, others might use different methodologies.

If you’re testing a young child or trying to be discreet about your collection, it’s advised to avoid the sort of tests that might use blood or hair samples in order to perform the test, as these can often be uncomfortable processes.

Results Delivery

Depending on your preferences, you might be happy enough to receive your results through an email or by logging into a secure online platform, but those who aren’t technologically minded may rather good old fashioned snail mail.

Whilst some DNA testing companies mail out your results as standards, others will only send your results the old fashioned way if you pay an additional fee, so be wary of which service you go for if this matters to you.

Frequently Asked Questions

Can a DNA test be done with just the father and child?

Yes! In fact, the majority of paternity tests only require a sample from the child and the alleged father(s), as this can present a Possibility Of Paternity level as high as 99.99% or more if the tested man is in fact the child’s dad.

Sometimes, though, there isn’t a high enough of a match to declaratively state fatherhood, in which case the biological mother would be contacted to provide a sample for corroboration, in order to determine a strong enough result either way.

A test can still be performed if the mother will not agree to participate, and you don’t need her there in most cases for a conclusive result. It just means that the results will be slightly less determinate than they could be.

What could affect the outcome of a DNA test?

Whilst only your DNA itself can provide the answers you’re looking for, it’s possible to obtain an ‘inconclusive’ result, which usually means the sample provided for testing was not of a high enough quality to determine reliable results.

Paternity tests will only have one of two possible outcomes, which are either:

0% probability of paternity, which indicates the alleged father has been officially excluded from being the biological dad, and therefore not considered the father in the eyes of DNA testing

99% probability of paternity essentially means the opposite - an alleged dad has not been excluded from being the biological father, and is therefore officially considered to be, at least according to that specific DNA testing company.

This could be because you did not yield enough DNA for testing. In a paternity test, for instance, the DNA collected from the inside of a cheek for a sample can be too weak, or overshadowed by the presence of too much saliva.

Failing to follow the instructions for obtaining a sample, usually including rules like not eating or drinking for an hour (besides water) before taking the test, and avoiding smoking or brushing your teeth, can also contaminate your swab.

In rare cases, it’s also possible that there are genetic differences between the child and the alleged father in multiple genetic markers, which are the factors used for testing for a DNA relationship between father and child.

Will a home DNA test hold up in court?

Unfortunately, unless you’ve had a court appointed or approved third-party there to perform or observe your sample, as well as following the other steps of the chain-of-custody process as required, your test won’t be admissible.

Luckily for you, however, we’ve provided you with an incredibly easy to follow four step guide to this process in our Buyer’s Guide above! It’s worth noting, however, that you should usually just follow the advice of your case’s judge or attorney on this.

Failure to do everything according to not only the laws of your state but the legislation of your particular court will result in a rejection for evidence.

Don’t waste your money - just do things by the book!
