Trusted Grandparent DNA Test | Premium 46 Marker Test

Reliability, Affordability, and Speed, that’s our commitment!  We do not offer our cheap pricing on the back of a low quality DNA test.

We stand behind the quality of the PRODUCTS & CUSTOMER SERVICE we offer.  The fact is, PaternityUSA.com is the discount website for the biggest & most trusted relational DNA testing lab in the USA that performs more relational DNA tests than any other in the USA.  Because of that, we are often imitated, BUT NEVER DUPLICATED!

It is not uncommon for test participants to live too far apart to get together and do the DNA collection.  For this reason we offer an option to have multiple collection kits shipped out for these situations.

When ordering, simply choose the option for an additional address, and complete the address in the order. We will send then second collection via the same shipping method as the first.

The collection kits are linked using a reference number and bar codes. When the samples are received back in lab, they are matched to your case using the bar code and reference numbers. This will generate an email advising you that we receives the samples.

In a scenario where the alleged grandchild is a male and the paternal grandfather is able to take part in the analysis, a Y-STR will conclusively determine whether or not they share the same male lineage.

On the other hand, if the relationship that is trying to be determined is on the mother’s side, an mtDNA will offer a conclusive answer regardless of gender.

Other relationship analysis may also be performed to help establish paternity or maternity, such as an Aunt Uncle or Sibling DNA test.

Lastly, if other paternal relatives are available to participate, a Family Reconstruction Test can offer a combined probability of relatedness to the family members.

The process is very simple. DNA is painlessly collected using a cheek buccal swab. Simply painlessly rub the swab against the inside of the cheek. In this process, skin cells collect on the swab.We conduct all of our analysis twice. For that reason, there will be 2 buccal swabs per person in your collection kit.

When all samples are in the lab, you are notified via email that the analysis has begun along with the expected release date. We email the results after the test has completed, and the hard copy results will follow as ordered.  The report is sent to the billing address unless otherwise noted.

We ship our collection kits with free USPS rushed delivery Monday through Friday to physical addresses in the contiguous USA. Orders received and processed by 12:00 PM EST ship the same business day.

Our grandparent DNA tests are highly accurate, typically providing very conclusive results with a high degree of certainty. The accuracy of the test depends on various factors such as how many markers are tested, if the mother or other grandparent is included, the quality of the samples collected, and the testing methodology used.

Our USA lab utilizes state of the art DNA testing technology combined with stringent testing protocols thus ensuring an accurate conclusive answer. Furthermore, our legal grandparent DNA tests are valid in court.

A grandparent DNA index greater than 1.0 indicates there's a higher likelihood the tested parties are really related as grandparent - grandchild.

A grandparent DNA index of less than 1.0 indicates the tested parties are less likely to be related as grandparent - grandchild.

Therefore, the higher the grandparent DNA index value goes over 1.0, the stronger the evidence is indicating that the tested parties are biologically related as grandparent - grandchild.

An informational test can provide you with the peace of mind of whether or not a biological relationship exists between the tested participants.

However, if you need the results to be admissible evidence in a court of law or other governmental domestic agency, then purchase our AABB accredited legal test.  Legal results can be submitted as evidence in child support, visitation rights, change name on the birth certificate, estate, wills, probate situations, and/or any other domestic legal case.

If your results are for immigration purposes, the USCIS/ICE & Dept. Of Homeland Security may require accredited DNA evidence of the grandmother or grandfather biological relationship. If so, contact us for information on a DNA test for immigration purposes.

The most common method of DNA collection is through a cheek swab. However, we understand there are times when test participants are unable to submit a swab.  When a family member is deceased, incarcerated or otherwise unavailable, you have the option to submit other types of DNA samples.  For these reasons, we offer forensic analysis for other types of DNA samples.

Ear wax, hair (must have the root ball attached), mucous on a tissue, finger or toe nail clippings, and toothbrushes are common forensic samples. Additionally, in certain cases tissue and/or blood samples may be available from a medical examiner or coroner’s office. Forensic sampling prices apply for any non-standard DNA sample. For pricing and more details on the process, please contact a Case Manager.

Our package comes complete with collection kits, lab analysis and results. Some companies advertise that you can make your own collection kit by using your own Q-tips®. However, we do not recommend this practice unless no other options exist. This mitigates the risk of multiple genetic profiles  being found on Q-tips® that are not sterile, or  handled by more than one person.
