The Genetic Reconstruction DNA Test is used when the alleged father cannot be tested directly. By comparing the child’s DNA with that of paternal relatives, the lab calculates a Combined Relatedness Index and a Probability of Relatedness, giving families clarity about biological relationships.

Who Needs to Be Tested

Option 1

• One (1) Mother

• One (1) Child

• One (1) Paternal Parent (PP) of the Alleged Father (AF)

• One (1) Full Sibling (FS) of the AF

Option 2

• One (1) Mother

• One (1) Child

• Two (2) Full Siblings (FS) of the AF

Note: Testing half-siblings of the deceased or untested alleged father is not recommended, as they do not share enough common DNA with the child.

Turnaround Time

• Standard: 5 business days from receipt of all samples

Chain-of-Custody Testing (For Legal Purposes)

Required for results admissible in court for inheritance, immigration, or other legal matters:

• Samples collected by a neutral third party (clinic or laboratory)

• Positive ID verified by government-issued ID, photo, and/or fingerprinting

• Official DDC kit used

• Client Identification & Consent Form (COC-4002) completed and signed

• Guardianship of minor verified at time of signing

• Clients may not handle kits before or after collection

Non-Chain-of-Custody Testing (For Personal Knowledge)

For individuals seeking results for peace of mind only:

• At-home buccal (cheek swab) kit provided

• Samples collected by individuals themselves

• Results not valid for legal purposes

• Report lists names exactly as provided on samples

• Each kit assigned a unique barcode for tracking

Important Notes

• The ideal testing scenario includes: mother, child, one paternal parent, and one or more full siblings of the deceased.

• Alternative testing with mother, child, and two full siblings of the deceased is also possible.

• Testing fewer relatives may produce inconclusive results, and the lab may recommend testing additional family members.

• Results are reported as:

  • Combined Relatedness Index (statistical odds of relatedness)

  • Probability of Relatedness (expressed as a percentage)

• Genetic reconstruction and siblingship testing are not as definitive as direct parentage testing.

Key Features

• Establishes biological relationships when the father is unavailable

• Results in 5 business days

• Legal (chain-of-custody) and non-legal options available

• Uses paternal relatives (parents/siblings of alleged father)

• Results reported with a Relatedness Index and probability percentage
