Grandparent

 

A grandparentage test is performed to determine a child’s relationship to the alleged father’s family when the alleged father is unavailable or unwilling and no post-mortem sample is available. By comparing the DNA patterns of both paternal grandparents with the child, we can determine a “probability of grandparentage.”

 

Who needs to be tested?

​

• One (1) Mother, one (1) Child, and both Paternal Parents (Mother [PM] and Father [PF] of the Alleged Father [AF])

 

Turnaround Time

• Five (5) business days from receipt of all samples

 

Chain-of-Custody Requirements

​

Chain-of-custody requirements must be fulfilled for test results to be defensible in any legal situation, such as inheritance disputes. These requirements include the following:

​

• Samples are collected by a neutral third party, such as a clinic or laboratory

• The individuals tested are positively identified (i.e., they present a government-issued ID to be photocopied and/or they are photographed and fingerprinted)

• A standard kit is used

• Each party completes and signs a Client Identification and Consent Form (COC-4002)

• Guardianship of tested minor must be verified at the time of signing consent

• The kit may not be in the possession of the clients prior to or after being collected

​

Non-Chain-of-Custody Requirements

​

In a non-chain-of-custody test, samples are collected by the patients themselves. Results of this test are for personal knowledge only and may not be used for legal purposes.

​

• An in-home kit is used, and buccal samples can be collected by the patients themselves at a time and place of their choosing

• Since the origin of the samples cannot be verified, names are listed on the report in the same way they are labeled on the samples

• A unique barcode is assigned to each kit and appears on the report as a reference for the case

​

Notes

• We strongly encourage the mother to participate so we can account for one-half of the child’s genetic material, which she passed along to the child
