Twin Zygosity DNA Test

A twin zygosity test is a DNA test that definitively shows whether twins are identical or fraternal.

When twins are born, the physician usually is able to tell whether twins are identical or fraternal by examining the placenta. Identical twins usually share a placenta, while fraternal twins are usually in two different placentas.

However, sometimes records can be lost, the placentas might have been discarded or damaged before twin zygosity was determined, or doubt may arise because of the twins’ physical characteristics. In such cases, only a DNA test will be able to reveal the truth. A twin zygosity test compares the twins’ DNA profiles to see whether they match—an exact match proves that the twins are identical.

The results of a twin zygosity test may be used to satisfy personal curiosity as well as to help solve health problems for the twins later down the road. For example, in the event that a twin needs an organ or tissue transplant donor, the identical twin is a perfect choice.

Identical vs. Fraternal Twins
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 have exactly the same DNA, although like other siblings, they can be expected to share some of the DNA they inherit from both parents

Tested Parties
Both Twins

DNA Testing Cost : Peace of mind
Both Twins DNA tests cost P.Rs 19950.

Turnaround Time :       Two Weeks

NOTE :
There are even rare cases where assisted fertility methods such as in vitro fertilization (IVF), can produce fraternal twins with different fathers. Should the sperm samples used in an (IVF) case inadvertently contains a mixture of different donor's sperm, any resulting Zygotes could have different fathers. While this is a rare occurrence, it has happened.

DNA Collection Kit
Collecting the DNA sample is quick and painless. Swab the buccal ( inner cheek ) of all participants.
Once you place an, we will send you a DNA sample collection kit within one business day. Testing kits are available at our Affiliate organization.

The kit will contain the following:

• Complete instructions for collecting the DNA samples, ( Video CD describing the whole Procedure )
• Buccal swabs and swab envelopes for the Both Twins
• Business return envelope for shipping the samples back to the DTA.

DNA Testing: The  Advantage
DTA (DNA Tells All.com ) in association with DDC leads the DNA testing industry in its quality of service, which focuses on ensuring DNA test accuracy as well as a smooth experience for our clients.
All our DNA paternity testing clients, enjoy many advantages which includes

• DualProcess™ — Run each test twice using the DDC DualProcess™ which follows the most stringent procedures to guarantee accurate and conclusive results.
• Legal Grandoarentage Test — Follow a strict Chain of Custody to ensure results are legally admissible.
• Confidentiality — Maintain confidentiality of each case using strict communication protocols

Legal Twin Testing
Legal DNA Testing requires Strict Chain of Custody Procedure.
Chain of Custody Procedure requires sample collection fees (Participant Paid this sample collection fees directly to sample collector).

You may also discuss your situation with one of our caring, confidential case managers by calling or e-mail.

Additional Tested Parties
We can test additional children, alleged fathers / mother if needed; there is a DNA testing and analysis fee of
P. Rs. 11950/= for each additional tested party. The additional tested parties need to be added to the case during setup (before the testing process is started in the laboratory).

For the associated fees, please review our fee schedule.

Although 16 (loci) DNA test is Industry standard for Paternity Testing.
Our Lab test 20 (loci) in all our Testing, a New standard in DNA Testing.
