Quality At Home Twin Zygosity DNA Testing
Twin DNA testing determines whether siblings are fraternal twins or identical twins. A twin zygosity DNA test may be used solely for personal curiosity or in some cases it can be used to help solve any health problems the twins may encounter later down the road in life. A perfect example, if one of the twins needs an organ or tissue transplant donor, the identical twin is very often the most perfect match.
Why Risk Using Your Own Q-tips® – We Overnight A Sterile Collection Kit To You For Free
Our twin DNA testing package is complete with testing kit, DNA analysis and test 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. There is a risk of multiple DNA samples being found on Q-tips® that are not sterile, or that may be handled by more than one person. Q-tips® you may have in your home could already have DNA from other sources on them. For this reason, we send a twin DNA testing collection kit containing sterile buccal swabs to you at no charge. We even ship the collection kit to you via FREE UPS overnight so you have your sterile medical swabs as ready for use the next day.

All of our DNA tests are performed by top-notch geneticists using proven scientific methods and state of the art equipment in our AABB accredited laboratory. Our service is simply unparalleled and our prices are very affordable. You can rest assured your DNA samples are secure and your results will be accurate. With today’s technology and inexpensive pricing on DNA relationship testing, there is no longer a need to go without knowing the truth about a biological relationship.
About Twin DNA Testing
Identical twins are formed from one fertilized egg. In early development, this fertilized egg, called a zygote, which usually develops into one individual child, splits to form two identical embryos. Because the twins both come from the same one egg and the same one sperm, they have the same DNA.
Fraternal twins however, develop from two different eggs fertilized by two individual sperm cells. Fraternal twins do not have exactly the same DNA, although they share some of the DNA, which they inherit from both parents. In some rare cases, fraternal twins may actually have different fathers.
Sometimes, before birth the doctor may be able to tell whether the conceived twins are identical or fraternal through an ultrasound examination. Or, determine this when the twins are born by doing an examination of the placenta.
These methods are not 100% accurate, however. Additionally, medical records regarding zygosity get lost, or doubts arise due to physical characteristics. Scientists recommend twin DNA testing to determine the zygosity of twins if the question lingers. In such cases, only by performing a twin DNA testing will you be able to reveal the truth regarding zygosity. A twin zygosity DNA test compares the twins’ DNA profiles to see whether they match—an exact match proves that the twins are identical while anything other than an exact match indicates the twins are fraternal.
Participants In Different Cities Or States
It isn’t uncommon for test participants to live too far apart to get together and do a twin DNA test collection. For these cases, we offer the option to have multiple collection kits shipped. When placing your order, simply choose the option for an additional address. We send each collection kit via overnight UPS. If you purchase a 2 day return mailer for just $5.00, we include it for all addresses on your order. When shipped, the collection kits are linked through reference number and bar codes. Then, when the samples are received back in lab, they are matched to your case through the bar code and reference numbers.
Legal Twin DNA Testing
An informational DNA test will provide you with peace of mind of whether or not a biological relationship exists between the tested participants. If you need the results for your twin DNA testing to be admissible evidence in a court of law or other governmental domestic agency, then you must purchase our AABB accredited legal twins DNA test. Also, our court legal twins DNA tests may be used as admissible court approved evidence in case of child support, visitation rights, change name on the birth certificate, estate, wills, probate situations, and/or any other type case where the identity of the tested parties must be proven by an AABB accredited DNA test. If your DNA test is for immigration purposes, the USCIS/ICE & Dept. Of Homeland security may require AABB accredited DNA evidence of the biological relationship. If so, then order our AABB accredited DNA test for immigration purposes.
Testing Process And DNA Sample Collection
The twin DNA testing collection process is very simple. DNA is collected on a cheek swab, also called a buccal swab. The swab is painlessly rubbed against the inside of the cheek. In this process, skin cells collect on the swab. We conduct all of our tests twice. For that reason, there will be 4 buccal swabs per person in your collection kit. Do two swabs on each side of the mouth. It is best to rinse the mouth with water and refrain from smoking or drinking coffee or tea for 2-3 hours before the DNA collection. Once the swabs have been taken, place the samples in the return prepaid pre-addressed mailer. Finally, simply drop the samples off at the courier’s location or box to send your kit back to the lab for testing.
When all samples are in the lab, you will be notified via email that testing has begun. We will email the results of your twin zygosity DNA test when the testing is complete, within 3-5 business days. If hard copy results are ordered, the report is sent to the billing address unless otherwise noted.
We ship our collection kits with free UPS overnight delivery Monday through Friday to physical addresses in the contiguous USA. Orders received and processed by 2:00 PM EST are shipped the same business day. Orders received after 2:00 PM EST ship the following business day.
Other Types Of DNA Samples
The most common method of DNA collection is through a cheek swab. However, we understand there are times when test participant is unable to submit a swab, such as may be the case where a family member may be deceased, incarcerated or otherwise unavailable. For such cases, we offer forensic processing services 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 or blood samples may be available from a medical examiner or coroner’s office. Forensic sampling prices apply. For pricing and more details on the process, please contact a DNA Case Manager.
Thank you for your immediate and prompt service...Highly recommendable for people seeking DNA Testings...Good job Paternity USA...Again thank you so much. Another VERY HAPPY customer 🙂
We just did a paternity test and used our doctor as the collector - the process was easy, legitimate and cheap! I highly recommend for those of us on a budget!
Awesome. Easy. Best Price Around! Got my son's birth certificate right now. Thank you all!
I purchased this Y-STR test to verify that my son is the father of my grandson. Now I know for sure this sweet little boy is my son's baby. Thanks Paternity USA for the peace of mind.
I took this test last month and my results were accurate. Easy process, good customer service and i like that they notified me of the status of my case all along the way. I always wondered and now I finally know for sure. I highly recommend you all every chance I get. Lisa L
I picked paternity usa for my immigration test for my mother and sisters. I'm so glad I did. Everything great - very good service and fast.
I don't usually write reviews, but I feel like this one is important. To have a lingering question of whether you belong in a family or not isn't anything easy to deal with. I wondered at first, because they are cheaper than everyone else, and felt like this is an area I shouldn't skimp on, but I'm so glad I picked these guys. I didn't skimp - I just found the best deal! My test result was very definitive and left no room for question. I want to let others know that you can find your answer and peace. Pick Paternity USA, they will do a great job. I can't say enough good about them. Thanks - Brenda
I am glad I chose this company for my paternity test. They scheduled an appointment for me and my daughter, it was within a couple of days, then the results were emailed to me less than a week later. I didn't have to do anything but show up for the appointment - they handled everything else from beginning to end.
Thank you guys for a process that is easy and quick. You've been so helpful! Jenn
I was given up for adoption and found a sibling through online records. We did the mtDNA test to see if we have the same mother (who is deceased), and I finally have been able to connect with my family. Even though I will always be thankful to my adoptive family, it's nice to add to that! Test was conclusive, process easy and good communication. Thanks 🙂
Immigration DNA Testing
The immigration process is a hard process for me and my family and PaternityUSA has experience and was able to help us through the whole thing. Happy with your service and I will let my friends know. Sincere thanks - the Claitte Family
I called PaternityUSA to help us with getting my children in from Jamaica, and so they performed the AABB accredited DNA test for immigration. The process only took (2) weeks, and everything was very smooth. I cannot thank these people enough.
I had bought a DNA kit at CVS pharmacy, but I wanted to see if I was the grandparent. I discovered that I could not use the drug store kit for a grandparent DNA test. I called paternityusa, and I'm very pleased with the work they performed. They really took the time to talk to me
I found my long lost brother after 40 years separation at birth. We did a y-str test, and it was very accurate. I happy to have my brother in my life again
This company did a wonderful job for our family, and we're so grateful we were able to find them on the internet. THANKS!!
