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. Sometimes twins just do not know if they are in fact identical or fraternal. This test will tell you precisely.
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.

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. For this reason, we rush you a DNA testing collection kit containing sterile buccal swabs to you at no charge. We also include a prepaid mailer to send samples back into lab.
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 you place your order, simply choose the option for an additional address. We send each collection kit for all addresses on your order within the contiguous USA with the same shipping method as the first. When multiple collection kits are ordered, 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.
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.
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 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.
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.
