Twin Testing

Want to determine if your twins are fraternal or identical? Twin testing is the answer!

This DNA test will analyze the DNA of the two siblings and look for commonalities and differences within their genes:

Identical twins: One fertilized egg split into two, and then implanted into the womb. (These two children will always be the same gender.) These twins share nearly the exact DNA.

Fraternal twins: This means two different eggs were fertilized at the same time and then implanted into womb. These two siblings may or may not look alike, and they can be different genders. These two are as genetically similar as they are with any other full siblings, but they share a birthday. These children do not have the same DNA.

When should you perform twin testing?

Our twin tests are most often performed after the babies are born – sometimes it can be months and on occasion, years. Oftentimes doctors can let you know if the two are identical or fraternal twins based on the placenta – but sometimes this information is lost

Many parents want to know for certain if the twins are identical or fraternal – and a DNA test is the only way to prove that. A cheek swab is all we need to collect a sample to test.

Why is this important to know?

In addition to the fact most parents and twins themselves want to know their twin type in general, it can also be beneficial in some medical situations. Because identical twins share the same DNA, they are the uniquely ideal match for blood transfusions or organ donations for one another.

However, in case you were wondering – they do not have the same fingerprint.
