What is a Family Reconstruction DNA test?
When close potential relatives are unavailable for testing, there may be other relatives who can help to fill in the gaps and determine a child’s genetic relationship to the family. DNA Family Reconstruction Testing is one of several tests that can help you get accurate answers fast.
This type of DNA testing is most often used for paternity tests, but can also be used to establish a genetic similarity between mother and child, grandparent and grandchild, siblings, and other familial relationships.
Genetic reconstruction is most commonly used when:
- A potential father refuses to submit to a DNA test
- A potential father is unreachable or had died
- One or more parties cannot be present for a DNA test
- An individual lives remotely and cannot provide a sample
- One wishes to keep the DNA testing confidential
Reconstruction Testing Options
For a genetic reconstruction test you have two options, depending on which paternal relatives are available for testing and whether the child’s mother is available to provide a DNA sample. If you can provide a DNA sample from the child’s mother, the test will also need to include at least two DNA samples of the alleged father’s family. The sample needs to come from a closely related, biological family member such as a mother, father, a brother or a sister.
For example. if you want to establish indirect paternity for the child but the suspected father is not available. There are no siblings to test against, and both paternal grandparents are not available, you can use the DNA from the mother, child, and two paternal aunts of the suspected father.
The second option is carrying out the test without the sample of the child’s mother. In this case, DNA samples need to be taken from at least three members of the father’s family in order to get an accurate match. The reason that three members of the family DNA needs to be collected is simple, it helps provide enough DNA for a strong genetic reconstruction and will show without a doubt that the alleged father contributed, or didn’t contribute, their DNA to the child being tested.
Using the same example as before, if the mother is not available, we could test a paternal aunt, a paternal uncle, and the child's grandmother for this type of test.
How accurate is a Genetic Reconstruction test?
The results provided on the results report are accurate for the relationship tested for, as they are based directly on the DNA profiles of those being tested. Wherever possible, we encourage the submission of a mother's DNA sample to be included in the testing.
Once the DNA analysis is performed, the markers are compared between the mother (if included), the relatives and child to establish if the child carries the genes inherited from his or her biological father. In this test we are looking to answer the following question: “do the alleged father’s relatives share the same genetic markers that the child inherited from his or her biological father?”
If the child does not share any genetic markers with their alleged father’s direct relatives, then it indicates that the alleged father is not the biological father of the child.
Genetic reconstruction testing is only available for private, non-court admissible results. In order to be legally admissible, those family members would need to validate their relationship with the suspected father prior to testing, to allow the legal test to show that all parties are legally related, or not related.
What is the cost of a Genetic Family Reconstruction test?
Journey Genetic Testing guarantees the highest quality testing at the most affordable prices. We process thousands of DNA samples every year for lawyers, physicians, adoption agencies, and private individuals.
Your cost will depend on several factors, with the most important one being who is available to test.
Your choices are outlined in the fee schedule below. In addition, each private test has two options available for DNA sample collection: you may choose to use a testing kit from Journey Genetic Testing or make your own DNA collection kit. If you chose to use a Journey Genetic Testing DNA Kit, you will receive detailed instructions, buccal swabs, collection envelopes and a pre-paid FedEx overnight return mailer (USA only). Once your kit is mailed, you will be provided a tracking number to be able to determine when it will arrive.
|Number Of People Testing||Processing Time||Cost|
|4 - Mother + Child + 2 Paternal Relatives||2 Business Days||$179|
|4 - Child + 3 Paternal Relatives||2 Business Days||$289|
|Each Additional Person||2 Business Days||$110|
|Each alternative DNA sample||5 Business Days||$125|
Family Reconstruction DNA Sample Collection
The most accurate method of obtaining DNA for an reconstruction DNA test is to use a buccal (mouth) swab, which is very similar to a "Q-tip" cotton swab. The swabs are rubbed on the inner cheeks of the mouth of those being tested. The process is simple and fast. We provide all the materials needed for the DNA collection in our Journey Genetic Testing Test Kit.
However, we know that sometimes it is not possible to obtain a buccal swab sample. We are often able to test discreet alternative DNA samples. To learn more about non-standard, alternative DNA samples that we can test, CLICK HERE.
Your DNA collection kit will have detailed step-by-step instructions on how to collect your swab sample. You can also read more about how to take a home DNA test by going to How To Collect A DNA Sample At Home.
If you need to send one or more of the DNA collection kits to a different address, we can do that as well. Just indicate how may collection kits you need when you complete the order form, and enter the addresses for each kit in the area of the form where it asks where the kits are being sent.
Making Your Own DNA Kit (MYOK)
All DNA test orders include a DNA collection kit sent to the designated address on the order form. We understand that you may be in a situation where you do not want anything being mailed to you, to allow additional privacy.
Journey Genetic Testing allows you the option to make your own testing kit when collecting and returning DNA samples to us. This option can save money on shipping a DNA kit to you, as well as save you time as you can ship directly to us without waiting for the testing kit to arrive.
To choose this option please select the "Make My Own Kit" option on the order form for the particular test you are seeking. You will find the order form on the information page for that particular test. For example, paternity test order forms are found on the paternity page, sibling order forms are found on the sibling page, and so on.
Upon finalization of your order (during regular business hours) you will be e-mailed a submission letter with your unique Journey Genetic Testing case number and the address for mailing your samples. The processing of the samples is conducted in the same time frame as if you used one of our kits - in as little as 1 business days for paternity, maternity, sibling, grandparent, avuncular, and twin zygosity tests!
Non-standard samples being submitted must fit into a standard envelope. If necessary please trim the item to fit (for example a hat band, a piece of clothing with blood, etc) into a regular envelope while making certain the specific area to be tested is included.
DO NOT USE PLASTIC WRAP OR A "ZIP LOCK" BAGGIE FOR STORAGE OF YOUR DNA SAMPLE. THIS MAY CAUSE THE SAMPLE TO DEGRADE AND A GENETIC PROFILE NOT BE ABLE TO BE GENERATED. LAB FEES WILL STILL APPLY AS EVERY EFFORT WILL BE MADE TO EXTRACT ENOUGH DNA FOR TESTING.
It is strongly suggested that if you reside outside of the United States and wish to order DNA testing that you use this option as the most cost effective and time efficient method to get the answers you need and deserve.
Please note that we are unable to process any DNA samples without a Journey Genetic Testing case number. Samples that arrive without a case number will be discarded.
Genetic Reconstruction DNA Test Results
The results from a genetic family reconstruction test will be similar to sibling, grandparent, and avuncular DNA results, in that it will give the stated probability of the relationship based on the genetic profiles of those who were tested.
A probability finding in the range of 91% up to 99.99% is considered as a conclusive results that the relationship most likely exists.
If the results show a probability of relationship of 9% or less, all the way to 0%, then it is highly improbable that the child is a son or daughter of the suspected father, whose biological relatives were tested.
The findings on this report are 100% accurate, as they are based on each person's genetic profile that was contributed to the testing process.
Part of a family reconstruction case, I worked with Journey Genetic Testing on behalf of a client and everything went through without issue. The result was well received and I’m grateful for their assistance.
