All testing performed by an accredited laboratory.
DNA Direct offers confidential, accurate, fast, and affordable twin zygosity testing services.
This DNA test definitively determines whether twins are identical or fraternal.
When twins are born, pathological examination of the placenta can also be done to determine zygosity. However, studies have shown that this method is not 100% accurate. Scientists recommend DNA testing to accurately determine zygosity.
Identical twins come from one fertilized egg, called a zygote. The zygote, which usually develops into one child, grows and splits early in development to form two embryos—identical twins. Because the twins come from one egg and one sperm, they have exactly the same DNA
Fraternal twins, on the other hand, develop when there are two different eggs in the mother’s womb that are fertilized by two different sperms. Fraternal twins will not share identical DNA.
We understand your need for results to remain confidential. Once testing is complete, we will only send results to the email address you provide when the order is placed. We will not issue results over the phone.
THE ANSWERS ARE ONLY DAYS AWAY.
A DNA collection kit by default comes with supplies for two individuals: 1 welcome letter with DNA kit activation instructions, 1 set of sample collection instructions, 4 buccal (mouth) swabs, 2 sample envelopes, and a polymailer envelope with a United States use ONLY prepaid return label.
Additional supplies will be included if additional individuals are being tested.
NOTE: The DNA Collection Kit for our Infidelity DNA Test contains sample collection instructions with pricing, 2 buccal (mouth) swabs for 1 reference sample, and does not include a prepaid return label or envelope.
STEP 1 - Activate your DNA kit by visiting the "Activate DNA Kit" link in the main menu. The email address you provide is the email address we will use to communicate with you and send the results to. Infidelity and Semen Detection kits do not need to be activated.
STEP 2 - Carefully follow the sample collection instructions, be sure to put the correct buccal swabs in the correct sample envelopes, and seal them.
STEP 3 - Place your sealed sample envelopes in the return polymailer and return your DNA kit to the laboratory. Be sure to check the prepaid return label for where to drop it off. It is also a good idea to write down the tracking number.
STEP 4 - When the laboratory receives your returned DNA kit they will thoroughly inspect it and confirm it has been activated. After that we will notify you by email it has been received and follow up with you in 1 to 2 business days with the results of your DNA test.
NOTE: If there are any issues with your DNA kit or the laboratory analysis, we will notify you immediately.
