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 4: 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 5: 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.

Often Asked Questions About Y-Chromosome DNA Testing

When Should I Choose A Y-Chromosome Test?

Y Chromosome testing can be used to establish indirect paternity when the alleged father is unavailable to test, or will not submit to the test. In these situations, we can test a direct male relative of the alleged father with the DNA of another male to confirm whether the untested alleged father is in fact related to the person claiming to be a biological relative.

It can be used when two siblings wishing to confirm whether they have the same biological father can do so by doing a Y Chromosome test. If there is a possibility that both alleged fathers are related, then either a sibling test, or direct paternity test, is recommended.

Adopted children who are searching for their real biological fathers, and perhaps have found a possible male family member, can use a Y Chromosome test in order to include, or exclude, potential fathers or paternal relatives.

Legal Y Chromosome testing can sometimes be used in cases requiring legal proof of relationship between males, such as probate or inheritance cases, or DNA proof for immigration.

Can A Y-STR Test Be Done Between A Male And Female?

No. Unlike a mtDNA test where the mother passes mitochondrial DNA to all her children, only a male child would inherit the Y-chromosome from his biological father. Since females do not have the Y-chromosome, this test cannot be used in these cases.

Are There Limitations To A Y-Chromosome Test?

Since every male from the same paternal bloodline have the same Y chromosome, the results of a Y-STR DNA test cannot tell you the specific relationship between the males tested. You will need to draw your own conclusions based upon the result of the test and what you are attempting to determine.

What Else Can Y-STR Testing Be Used For?

Y-chromosome testing is used in criminal forensic investigations and cases involving rapes. If a genetic sample is found at a crime scene, testing for the Y chromosome can establish whether there is any male DNA in the sample. Once the Y-chromosome has been confirmed, it can be compared to the Y-chromosome profiles of suspects to confirm a match.


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 an examples of a Y-Chromosome Comparision test report below to give you an idea of what the results you receive will look like. 

This specific test wo;; always have only one of two results, and they are guaranteed to be 100% accurate. The results will either indicate that the males tested cannot be excluded from the same male line or they are excluded from the same male like. Not excluded means they share the same male lineage which will verify paternity or another paternal male relationship in that same family. Exclusion means that the DNA shows they do not belong to the same male lineage and are not related to any males in that biological family.

The example below shows what an "exclusion" result may look like.

Our staff of trained professionals will be available after you receive your results to make certain you understand them and answer any questions you have.
