Test Description

We use a non-invasive, pain-free DNA collection method for Twin testing and DNA analysis. Using the latest technology, a buccal cell sample taken from the inside of the mouth is now the newest and most recommended method for sample collection. A buccal cell sample can be collected quickly, painlessly and discreetly using the home collection kit.

How to Read a DNA Test Report

Conclusions: There are two possible outcomes in a DNA Twin test:

Identical Twins

Identical twins will have exactly the same DNA profile as identical twin originate from the same sperm and egg. If the twins are identical twins, the report will clearly state that they are identical twins.

Fraternal Twins

Fraternal twins will not have the same DNA profile as fraternal twins originalte from two different sperm fertilizing two different eggs. If the twins are fraternal twins, the report will clearly state that they are fraternal twins.

FAQs

Every person has two copies of each gene. One copy comes from the mother and the other copy comes from the father. Identical twins occur when a single egg is fertilized by a single sperm to form one zygote which later divides into two separate embryos. Since identical twins originate from the same embryo, they will have exactly the same DNA profile. DNA twin testing can conclusively determine whether a set of twins are identical twins.

Fraternal twins occur when two different eggs are fertilized. Fraternal twins will have different DNA profiles from each other, much like regular siblings. DNA twin testing will conclusively determine whether twins are identical or fraternal (not identical).

When a DNA twin test is performed, the laboratory usually examines many different genetic locations. The more genetic locations that are examined, the more powerful and accurate your test becomes. After examining many genetic locations, a DNA lab can conclusive determine whether the tested twins are identical twins or fraternal twins. Our win test report will provide you with a simple “Identical” “Fraternal” conclusion for your twin test as well as a detailed report indicating the genetic profiles of each tested individual. A glossary of terms and results interpretation sheet is also provided with your results and is intended for individuals who would like to understand their genetic report and detail and to understand how the conclusion of the test was obtained.

Both the Legal and Private tests are equally accurate and both will provide absolutely conclusive results. If you choose the private test, a home kit will be sent to you so that you can collect the samples discreetly in private. If you choose the Legal Test, the collection must be done by an unbiased individual (doctor, lawyer, notary, etc.) and all individuals attending the collection appointment must bringa passport photo, picture identification, and they will be fingerprinted during the sample collection appointment. If you do not need to use the results in court, then the private option will provide the same conclusive results as the legal test and can be done discreetly.

If the parties to be tested living different cities or different countries, the kit can be split and sent to each individual separately. The kits are indivdividually barcode labelled so once the samples arrive back at the laboratory, they will be sted together. To order a split kit, please write the following into the comments box of the online order form when you place the order “Please split kit. Please send one of the twin’s portion of the kit to: (first twin’s name and address), and please send the other twin’s portion of the kit to: (second twin’s name and address).”

CODIS stands for Combined DNA Index System. The CODIS loci are the loci which are approved by the FBI and other recognized standardization bodies worldwide for databasing and genetic profiling. At International Paternity Labs, 13 out of the 16 loci which we test are CODIS loci. As such, the profile obtained from each test far exceeds the current recognized standards.
