A twins test (also called “twin zygosity”), is a DNA analysis that definitively shows whether twins are identical or fraternal.
During OB-GYN visits, the physician might be able to tell whether twins are identical or fraternal through ultrasound examination of the placenta. There are cases, however, where twins find out much later that a DNA test shows the opposite of what the ultrasound examination determined! Scientists recommend DNA testing to determine zygosity—the degree of similarity. Medical records regarding zygosity may have been lost, or doubt may have arisen because of the twins’ physical characteristics as they age.
This test will mark 20 loci markers instead of the usual standard 15 or 16 that other DNA companies may provide and can be upgraded to our 25 loci marker test for an additional $25.
This is a more accurate and conclusive test.
. If you need more than three people to test, please order an Add-on test for $100 US ($125.00 CN) for each additional person, Eg: another child, or alleged father, etc.
Please inquire for other types of tests, or multiple complicated situations. (Ancestry, cousins, half brothers or sisters, grand parents, multiple fathers, etc.)
