Methods of the DNA Grandparent Test
During a DNA Grandparent Test, a buccal (mouth) swab sample is collected from the child and the alleged grandparent. 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 child is compared to that of the alleged grandparent.

A statistical analysis is performed based on the match type typically expected for true grandparent/grandchild pairs, and a “grandparentage index” is obtained.

  • Biologically related grandparent/grandchild pairs are expected to have a grandparentage index value greater than 1.0
  • The greater the grandparentage index value, the higher the likelihood that the two individuals are biologically related as grandparent/grandchild
  • Pairs who are not grandparent/grandchild are expected to have a grandparentage index value that is less than 1.0

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.
