Precise Legal Y-STR Male Lineage DNA Testing

Y-STR Male Lineage DNA Testing Our legal Y-STR male lineage DNA testing is a very conclusive test that will answer the question – are the tested males from the same paternal line.  The test focuses on the Y-STR (Short Tandem Repeat) from the Y-chromosome that is passed from male to male.

The Y-chromosome produces a variable sequence that is almost as unique as a fingerprint and is passed from father to son.  This sequence will be virtually identical in an unbroken male lineage for generations.  If the tested males are from the same paternal line, they will have matching Y-STR profiles.

The cost of legal Y-STR male lineage DNA testing includes analysis for 2 males.  You can have the legal DNA collections performed at your doctor's office, or at one of our more than 33500 locations in the USA.  More test participants can be added if needed however.

AABB Chain Of Custody Requirements

The AABB guidelines stipulate that for legal Y-STR male lineage DNA testing to be binding or court admissible test must have valid chain of custody. Simply put, chain of custody refers to the DNA collection in the presence of a medical professional and the legal identification of the test participants. In any legal DNA test, the sample collection must be performed by a neutral medical professional who has nothing to gain or lose from the result of the test. You may not choose the collector for your legal DNA test unless you use a doctor's office. Our lab has a network of more than 5,000 locations where your DNA samples can be collected.

Our legal Y-STR male lineage DNA testing services are performed by top-notch geneticists using proven scientific methods and state of the art equipment.  You will find our client service simply unparalleled and our prices are very affordable. In reality, many smaller labs are not really AABB accredited; they only claim to be. They sell you a legal DNA test, then when samples are sent in, they forward them to another lab (of their choosing) for processing. This extra step takes longer and risks the viability of your DNA. With PaternityUSA, your test samples go directly to our AABB accredited laboratory, DDC (DNA Diagnostic Center).

Why We Stand Above The Others

Smaller companies who advertise cheap DNA testing allow participants to choose their own collector. Surprisingly, they even mail the collection kit right to the client. Please beware - this practice does not follow AABB chain of custody requirements. Their cheap sibling DNA test can end up being very costly to your family down the road.

It's a direct violation of AABB requirements for anyone associated with the legal Y-STR test to be in the possession of the collection kit. This includes any test participant, family members or friends. When swabs have been in the possession of someone with an interest in the test result, there could easily be suspicion of tampering. For this reason, we never ship any legal DNA collection kit to anyone other than a doctor's office or clinic.

Secondly, a legally binding DNA test must be collected by a medical or clinic professional. With, you can use your doctor for the DNA collection, or opt for professional collection service at one of our more than 5,000 clinic locations. Again, having someone known to the test participant act as a collector, or "witness" the DNA collection, does not meet AABB standards. A collection by an associate, friend or family member can easily be discredited; causing you to have to pay for another test.

A legal test conducted outside of the chain of custody is easily contested and disputed in court; and more importantly will not stand up as evidence.

In contrast, we don't bend guidelines that may risk injuring your case. Our lab follows every AABB requirement to help ensure your result stands up in any legal matter facing your family. We understand the need for a legal DNA test is usually accompanied by a difficult situation. With that in mind, we handle every case with care and confidentiality.

The Legal Y-STR Male Lineage Testing Process

The legal Y-STR male lineage DNA testing process is quite simple. When you place your order, you may choose to use our professional collection service (at one of our clinic locations) or have a test collection kit shipped free to your doctor's office.

If you opt to use your own doctor for the DNA collection, simply provide their address information when placing your order. We ship a legal DNA collection kit to them. We also provide a prepaid return mailer in the collection kit for their convenience. Check with your doctor first to be sure they perform this service.

Or if you prefer full service Y-STR testing, choose our professional collection option. A consultant will give you a call to schedule your appointment at your convenience. We have over 5,000 clinic locations across the country to serve your collection needs.

After the collection, the samples and chain of custody documentation go directly to the lab. When received, we email you a confirmation email to let you know testing is underway. If you order email test results, we email a PDF document of your notarized test result as soon as testing is complete. A hard copy is mailed to the billing address on your order. We do not ship anything to you other than the result for our legal Y-STR tests.

DNA Collection

The collection process is very simple for our Y-STR male lineage tests. DNA is collected through a cheek swab, also known as a buccal swab, which is painlessly rubbed against the inside of the cheek. Our lab conducts all of our sibling DNA tests twice. For this reason we collect 4 swabs per person. As a general rule, be sure the mouth is clean before swabbing by rinsing with water. Participants should refrain from drinking coffee or tea or smoking for 3-4 hours before the DNA collection.

In cases where a family member may be deceased, depending upon the details surrounding the case, tissue or blood samples from the medical examiner or coroner’s office may be available. Their office should be able to advise you of what is preserved. Once you have established this information, call us to speak with a Case Manager to discuss your situation and how to proceed.

Other Types Of DNA Testing Services

A Y-STR male lineage DNA test is only done between two males, as the Y-chromosome is only passed to males by their father.  If two males are not available to take part in a Y-STR male lineage DNA test, we do have other testing options for you and your family.  A paternity or maternity test will always be conclusive. A grandparent test would be conducted using one or both of the alleged parent’s biological parents.  A siblingship, or sibship, test would be a test done with another child who may share the same parent(s).  If the alleged parent has a full brother or sister, an avuncular aunt/uncle DNA test is another option.  Additionally, an mtDNA mitochondrial test will conclusively determine whether or not the test participants are from the same female lineage and can be done with either gender.

While our legal Y-STR male lineage DNA testing provides a court admissible certificate to prove a male lineage, if you find you only need results for your own peace of mind or curiosity, our informational Y-STR test may be best.  Whether you chose informational or legal Y-STR male lineage DNA testing , rest assured that you are in good hands with PaternityUSA.  Since our lab is AABB accredited, both legal and informational paternity test samples are processed in the same manner once the samples are in the lab.  The difference lies in the collection method - chain of custody.
