Grandparent DNA Test (Family Relationship Testing)

Confirm biological relationships across generations with accurate, accredited DNA testing.

The Grandparent DNA Test is designed to determine whether a child is biologically related to one or both grandparents, especially when the alleged parent is unavailable for testing.

This test analyses a large number of genetic markers (loci) to evaluate shared DNA between the child and the alleged grandparents, providing powerful evidence of biological relatedness across generations.

Because grandparents share approximately 25% of their DNA with each grandchild, advanced statistical analysis and expert interpretation are used to produce a conclusive likelihood ratio for biological relatedness.

Key Features

• Price: R3 000 per person (min. 2 individuals)
• Who Can Be Tested:

  • In-person testing at our Sandton office, or
  • Home collection kits are couriered discreetly across South Africa

How It Works

1. Sample Collection: Cheek swabs are taken from the child and one or both grandparents.
2. Genetic Analysis: The lab tests 24 or more DNA markers to identify shared DNA sequences.
3. Statistical Comparison: A genetic relationship index is calculated to determine the likelihood of a biological connection.
4. Results: Comprehensive and confidential results are delivered securely via email within 10–14 working days.
