What you get with this test
Detailed Description
This at-home DNA Grandfather Test kit is perfect for assessing the likelihood of a biological relationship between a grandfather and grandchild when the parents cannot be tested directly. The easy-to-use kit allows you to collect a mouth swab discreetly in the comfort of your home and send it to our lab for analysis. Results will be available for download from your secure online account within 1-2 business days after the lab receives your sample.
The test can be taken by the grandfather to determine if a genetic relationship exists with the grandchild. If the parents are available for testing, we recommend using the DNA Paternity Test or DNA Maternity Test instead of the grandfather test.
Technical Information
In a DNA Grandfather Test, a buccal (mouth) swab sample is collected from both the child and the potential grandfather. These samples contain cells, which hold DNA (deoxyribonucleic acid)—a unique genetic blueprint similar to a fingerprint.
In the laboratory, DNA is extracted from the cells and specific regions are amplified using a process called PCR (polymerase chain reaction). Our test examines 16 to 27 of these regions, known as short tandem repeats (STRs). STRs are areas of DNA where a short sequence is repeated multiple times, and they vary greatly among individuals. Analyzing these STRs provides a precise method for confirming or disproving biological relationships.
Precise Analysis
Our Extended Panel system examines up to 27 markers, setting the standard for the highest precision in the industry.
2x Testing Guarantee
Each DNA test we perform is independently conducted twice, ensuring 100% accuracy in every result.
