DNA and Paternity testing FAQs

Can I do a paternity/maternity test without the father or mother (deceased or unavailable)?

It is possible to establish paternity even without doing an paternity test. Paternity can be established by testing relative of the alleged father or your sibling (Ex: Grandparent, Avuncular, or Y-STR test). If only the child and relative of alleged father are tested, the results may not be as accurate. If the mother’s DNA sample is available for the testing, the results will be more conclusive.

How long can DNA samples last?

The DNA found in saliva, blood, and other biological material can be stored for a long time. However we always recommend collecting fresh samples for successful DNA extraction. If swabs are used, it’s important to leave swabs to dry completely before being placed in an envelope and sending to the laboratory.

What can be tested for DNA in an infidelity analysis?

We are able to analyze suspiciously stained items, garments, bed sheets etc. that may have semen, saliva or DNA material on them. Our laboratory can perform tests to detect the presence of DNA, semen, or saliva. Further DNA comparison testing can then be performed to determine if the DNA found belongs to the person requesting the test or another person. Click Here for examples of samples.

What is the difference between an Informational (Home) DNA test and Legal DNA test?

The Informational or Home DNA test, such as a Home Paternity DNA Test, is suitable for individuals who wish to find answers before taking the next step, or simply for peace of mind. When a private home test is ordered, a buccal swab (mouth swab) DNA kit is sent directly to the parties involved in the test for sample collection. The sample collection process is quick and easy and takes just minutes to complete. If the participants live at different addresses or even in different states we can send separate kits to all involved using our Split Kit Add-on.

The Legal DNA test, such as a Legal Paternity DNA Test, is intended for court use and is accepted as legal proof of relationship in court. A collection kit will be sent with instructions to an unbiased third party (collection agent, doctor clinic, or unrelated party, etc.) who must adhere to the chain of custody to ensure it is legally acceptable.  This kit cannot be sent to the home of, handled by a participant in the DNA test or a relative of any participant in the test.  Failure to provide a third party address may invalidate the results.

How old does a child need to be before testing?

DNA testing can be performed on individuals at any age. Sample collection can even occur on the day of birth.

Does the mother need to be tested for a paternity test?

No, not if only the alleged father is in question. While a conclusive answer regarding paternity can be obtained without testing the mother we recommend including a sample for comparison.

Does the mother need to participate in DNA tests such as an Avuncular or Grandparent test?

We highly recommend it. Having the mothers sample to compare and contrast the samples against will increase the accuracy of the test. If the mother does not participate there is a significant chance the test results will come back inconclusive.

Can paternity be determined if the alleged father is not available for testing?

If the alleged father is unavailable and his parents are alive, a Grand-parent DNA test can be collected. If he has any siblings, then an Aunt or Uncle (Avuncular) DNA test can be performed. If the alleged father has other children, then a full or half Sibling DNA test can be done. Also forensic DNA testing may be considered an option using items which may contain the alleged father's DNA. Forensic DNA testing can be performed any anything that has biological material from the father such as an old toothbrush, electric razer, blood stains, saliva stains, and teeth (This type of test will be created and tailored specifically to the clients needs. Please contact us in this event prior to ordering the test).

How is the DNA sample collected from a buccal swab?

DNA is collected by rubbing a brush gently inside the mouth against the cheek for 15 seconds. The swab will collect squamous epithelial cheek skin cells which contain DNA. The collection is safe and painless and can be performed on individuals at any age, including infants. 

In order for the tests to be as accurate as possible please allow the swab to dry before placing mailing. Allowing the swabs to air dry (do not use heated elements to force the swab to dry. i.e. hairdryer) will help to prevent contamination.

How accurate is a paternity DNA test?

Our paternity tests are extremely accurate in answering questions of parentage. Since we report 23 different genetic markers (we actually test for more) to build the genetic profile, our test is over ten times more accurate than legally required. And even more accurate than DNA collected by the Federal database, known as CODIS. The results are in excess of 99.99% for paternity tests, and can reach an even higher accuaracy if the mothers sample is also included.

What payments options are available?

We currently accept all major credit cards (Visa, MasterCard, American Express, Discover), Apple Pay, and PayPal as payment.

Unfortunately we do not offer any payment plans or deferred billing.

How long can I store the samples after collection before shipping it to the lab?

We recommend that you send the samples back to our laboratory for testing as soon as possible after sample collection. However, the samples are stable at room temperature and can stay viable for quite some time. But we do recommend, for best results, to send them as quickly as possible.

How will I receive my DNA test results?

Test results will be emailed to the email address provided at checkout.

If you want your results sent to multiple emails please let us know when upon checkout in the Additional Info section, Contact Us through our website, or email us at Info@ValidityGenetics.com with your order number and the email address to send the additional info to.

How long does it take to get the results of the DNA test?

We can proudly say we have the fastest turn around time for DNA and genetic testing in the industry, but this also depends on the type of test ordered.

For most informational and legal tests it takes as little as three (3) business days* from the receipt of the sample at our laboratory. 

Infidelity and cases involving special samples or forensic DNA work it will take a minimum of five (5) or seven (7) business days from sample receipt at our laboratory. The turn around time for special order forensic DNA testing will vary on the test performed and can be in excess of several weeks depending on the samples provided.

For Non-Invasive Prenatal Paternity Testing takes up to seven (7) business days from receipt in the mail.

Rush processing is available to expedite turnaround times on most cases.

*Business days are defined as normal working days (Monday through Friday) not including holidays.
