DNA Twin Test

The DNA Twin Test will conclusively determine whether a set of twins are identical or fraternal. Identical twins are genetically identical and will share exactly the same DNA profile, whereas fraternal twins only share approximately 50% of their DNA in common. This test can also be used for triplets, quadruplets etc.

Methods of the DNA Twin Test
During a DNA Twin Test, a buccal (mouth) swab sample is collected from each twin. The sample contains cells, and most of the cells in our body contain a full set of genetic information in the form of DNA (deoxyribonucleic acid). A person’s DNA represents a “genetic blueprint” and, like a fingerprint, it is unique to each individual.

At the laboratory, the DNA is extracted from the cell and specific regions of the DNA are amplified by a process known as PCR (polymerase chain reaction). The DNA pattern of the twins are compared to conclusively determine whether the twins are identical twins or fraternal twins.

Splitting the kit
If the individuals to be tested live in different cities, or even different countries, the DNA collection kit can be split and each component sent to a different address. The components are individually barcoded and the buccal samples will be tested together, even if sent back separately.
