READ OUR TESTIMONIALS
“My ex-girlfriend contacted me to say that I may be the father of her 5 year old daughter. Your test proved that I am the true biological father. It’s a life changer. Thank you.”
“I was very impressed with the ease and discretion of the testing process. I received my results quickly and quietly.”
“My husband has always mentioned that our two children maybe did not belong to him and accused me of being involved with his friend at the time that our children were conceived. I knew that this was not true. We finally decided to get a paternity test done to put an end to this. Sure enough, the results of the paternity test indicated greater than 99.9999% that he was the father of our children. Our family is now closer than ever before.”

“A++++. Near the date that my test was scheduled to be completed, I was so nervous that I ended up calling your lab almost once every hour. Thank you for putting up with me. I won’t forget your kindness.”

Are They Identical or Fraternal?
Knowing whether twins are identical or fraternal is often difficult. Appearance alone often is not a reliable method for determining twin zygosity because identical twins do not always look exactly the same, and fraternal twins can sometimes look very similar, leading to confusion about exactly what type of twins they are. Sometimes, twins grow up never knowing for sure whether they are identical or fraternal.
Determining Twin Zygosity at Birth
At the time of birth, the physician will try to get an idea of whether twins are identical or fraternal by examining whether they share the same sac. Identical twins often form in a single sac, sharing a placenta and amniotic membranes. Fraternal twins often form in two separate sacs. However, up to 25% of the time, this method of determining twin type is not accurate and can be very misleading. In some cases, twins can have two sets of outer sacs (dichorionic) and still be identical twins. Also, the two placentas of fraternal twins can sometimes fuse together and appear to be one.
Conclusive Determination of Twin Zygosity Using DNA
The only way to conclusively determine whether twins of the same sex are identical is through a simple DNA test. For this reason, many parents of twins will consider a private DNA test for twins to determine conclusively whether the twins are identical or fraternal. The DNA twin test is fast, simple and painless. A DNA sample is taken from each child by rubbing a painless swab gently inside the child’s mouth for ten seconds. The samples are then submitted to the laboratory for testing and conclusive results are available within 3 to 5 business days.
