Twin DNA Testing in San Antonio

Twin Zygosity DNA Testing in San Antonio: The Only Way to Know for Sure

All pairs of twins are either identical (monozygotic) or fraternal (dizygotic). Contrary to what you may have thought, you usually can't tell the difference just by looking at twins, especially when they're younger. Even some traditional indicators of zygosity used in San Antonio, like the number of placentas present at birth, are often misinterpreted or inaccurate. The only surefire way to know zygosity is by comparing the twins' DNA with profession San Antonio DNA testing.

What Is Twin Zygosity DNA Testing?

Dizygotic, or fraternal, twins occur when two distinct eggs are each fertilized by a distinct sperm. In rare cases, dizygotic twins can even have separate fathers. Monozygotic twins, on the other hand result when one sperm fertilizes one egg, and that embryo splits into two. That means that for monozygotic, or identical, twins, a San Antonio DNA test will show them to contain exactly the same genetic material, because their DNA came from the exact same gametes.

A twin zygosity test from Fastest Labs of San Antonio simply analyzes the DNA of each twin and checks whether or not they are the same. A simple DNA test can show conclusively whether or not a pair of Texas twins are identical or fraternal. That knowledge carries implications beyond the satisfying of curiosity; identical twins are genetically more compatible with each other, meaning they are excellent candidates for all kinds of organ and tissue donations. At Fastest Labs of San Antonio, we conduct all DNA tests professionally, quickly, and accurately. That's the Fastest Labs way.

Donor Qualification Process

San Antonio Twin DNA Testing Services

Assess and understand your options!

When it comes to organ and tissue donation in Texas, many times the most difficult part of the process is finding a match. Family members are much more likely to qualify as donors, and the most likely to do so are identical twins. Fraternal twins only share as much DNA as typical siblings, while identical twins are for all intents and purposes genetic matches. That means an identical twin can be counted on to provide organs and tissue to his or her twin with the highest possible success rate. A San Antonio DNA can let you know ahead of time whether twins are optimal donors. That information isn't always necessary, but in emergencies, it can save valuable time in moments when it's really needed.

Be prepared for medical emergencies!
