Is It Better To Test With A Grandmother Or A Grandfather?

If the child at question is a male, and the grandfather is available, we suggest you test male to male. When testing 2 males for a relationship DNA test, they have the extra advantage of including Y chromosome testing, if it is necessary. Y chromosomes are an exact match down the male lineage.

If the grandfather is not available, the lab makes the necessary adjustments to test a grandmother and possible grandson.
When the child in question is female, a DNA test with either the grandmother or the grandfather can typically provide sufficient and accurate results in most cases.

My Grandchild Lives In A Different Location. Can I Still Test?

It is very common for those who are taking a DNA test to live at a distance that makes it not practical to get together and do the DNA collection together. We provide an an option on our order form to have additional DNA collection kits sent to additional addresses.

To order additional kits, simply select the number required on the order form and provide the corresponding addresses in the designated section for the shipping destination.

We connect our DNA kits through a shared case number. After all the samples have arrived at the laboratory, our team cross-references them using the unique case number assigned to your particular case. We will notify you once all samples have arrived and testing has begun.

Is It Possible to Perform a Legal Grandparent Test?

Yes. If you are needing a DNA test for death benefits, immigration, probate, or to prove the relationship to the IRS or other government agencies, then you will need to a legal Grandparent DNA test. If the grandparents are alive and willing to take the DNA test, they are excellent choices, especially if the father is no longer alive. It is best to add the biological mother to the testing in these situations, if possible.

Can I Test Something Other Than A Mouth Swab To Be Discreet?

Yes! Alternate samples are very common to use when you want to have the testing run in a very discreet way. To learn more about this option, click on Alternative DNA Samples.

Do The Parents Need To Know I Am Testing My Grandchild?

We believe that open and honest communication is always best.

If you are looking for personal information using our at-home Grandparent DNA kit, you can discreetly and privately perform the test between the grandparent(s) and grandchild, without anyone else being aware of it.

If you are needing a legal DNA test, then the custodial parent or legal guardian will need to give written consent.

Are My Grandparent DNA Results Confidential?

Yes! Only the person who orders the test has access to the information. We never discuss results with anyone else to ensure your privacy.

Can A Grandparent Test Provide Results That Show Ancestry Or Health Issues?

Unfortunately not. Grandparent DNA tests primarily concentrate on identifying genetic matches with the other individuals undergoing testing.

Step-By-Step Directions

The mouth (buccal) swabs are packaged in sterile packaging. You will have two packets. Each packet contains TWO swabs. You will use all 4 swabs for each person.

Step 1: Complete the information on the DNA collection envelopes. The names listed should be the same as you put on your order form. There will be one collection envelope for each person whose DNA is being collected.

Step 2: Open the paper packaging and remove the swabs. Please be careful to handle the swabs on the long handle (the non-cotton end) only. DO NOT, at any time, touch the cotton end with your hands or fingers.

Step 3: With clean dry hands, collect cheek cells by rolling the tip of the sample collection swab firmly on the inside of the right cheek and under the tongue for 20-30 seconds. Be sure to roll the swab over the entire inner cheek surface. Repeat this process for the same individual with the second swab. You should use two swabs on the inside of the right cheek and two swabs on the inside of the left cheek.

Repeat the process for every individual being tested using a different set of swabs and envelope for each person.

Step 3: The mouth swabs should be dry before putting them into the collection envelope. The best way of doing this without risking contamination is to place them in an upright position in a clean dry glass. Do not put more than one person's DNA samples into a glass at a time. The DNA samples of each person must never touch each other. Once they are dry, place them back into the correct envelopes.

Step 4: Place all of the swab envelopes, plus and any included forms that you have completed, into the large pre-paid FedEx return envelope. Then simply return them to a FedEx office or call FedEx to pick it up at a time that fits your schedule.

Your DNA test results will be easy to read and understand. We will also provide you with our "Understanding Your DNA Results" booklet.

We are providing examples of Grandparent Test reports below to give you an idea of what the results you receive will look like. 

In this first example, the genetic test results show that the grandparent tested is the biological grandparent of the child.

Grandparent Inclusion

In this second example, the test results indicate that the genetic evidence does not support the grandparent who submitted their DNA being biologically related to the child.

Grandparent Exclusion

As you can see, the reports provide the information needed to know the likelihood of a biological relationship. Once you get your DNA report back, if you have questions, we are happy to provide you with help if needed. 

Our testing is the next step in your journey to truth about your family!
