Turnaround Time

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 High 5 Fingerprinting.
  • 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 DNA kit is used
  • Each party completes and signs a Client Identification and Consent Form
  • 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 can be collected by the patients themselves or assisted by collection site (High 5 Fingerprinting). 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, or assisted by collection site, 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 will appear on the report as a reference for the case
  • Barcoded kits are assigned to your account for easy reference 

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
  • When testing one grandparent, always consider testing the grandmother in lieu of the grandfather if she is available. As with all paternity testing, the father (and the grandfather in this scenario) may be in question
  • If the laboratory determines the results are inconclusive, they may suggest testing additional relatives. Future testing carries additional costs, so please contact your case manager with questions on pricing
