A DNA Grandparent Test (also known as a Grandparentage (GP) Test) determines the biological relationship between a child and their alleged grandparents. This test is most commonly used to indirectly establish paternity when the alleged father is deceased, incarcerated, or otherwise unavailable for testing.
By comparing the genetic markers of the child against those of the paternal or maternal grandparents, our laboratory can calculate the probability of relationship based on the 25% genetic material typically shared between these generations.
Why Choose the DNA Grandparent Test?
- Establish Paternity Indirectly: Verify if a child is biologically related to the alleged father’s family.
- Legal & Inheritance Claims: Provide supporting evidence for estate settlements or social security benefits.
- Peace of Mind: Resolve family doubts with scientific certainty.
- Non-Invasive Process: We use simple buccal (cheek) swabs, making the collection painless for both infants and the elderly.
DNA Grandparent Test Price in Kenya
At Zote, we believe in transparent pricing for all our molecular diagnostics. The cost of a Grandparent DNA test varies depending on the number of participants (e.g., whether one or both grandparents are tested).
| Test Option | Estimated Price (KES) | Recommended Participants |
| Single Grandparent Test | KES 28,500 | Grandparent + Grandchild |
| Duo Grandparent Test | KES 35,000 | Both Grandparents + Grandchild |
| Complete Kinship Trio | KES 42,000 | Grandparent(s) + Mother + Grandchild |
Critical Instruction: For the highest accuracy, we strongly recommend including the child’s mother in the test. This allows the lab to “filter out” the maternal DNA, making the remaining paternal markers easier to match with the grandparents.

Reference Ranges & Interpretation
DNA results are presented as a Kinship Index and a Probability of Relationship.
| Result Metric | Value | Interpretation |
| Likelihood Ratio (LR) | > 1.0 | Supports a biological relationship. |
| Likelihood Ratio (LR) | < 1.0 | Strong evidence of a biological relationship. |
| Probability (%) | 90% – 99.9% | Strong evidence of biological relationship. |
| Probability (%) | < 10% | No biological relationship detected. |
| Inconclusive | 10% – 89% | Additional testing (e.g., the other grandparent) suggested. |
Important Information
- Fasting: No fasting is required for this test.
- Preparation: Ensure the mouth is clean. Avoid eating, drinking, or smoking for 30 minutes prior to the cheek swab collection.
- Legal vs. Peace of Mind: Please specify if you require a “Chain of Custody” (Legal) test for court purposes, as this requires witnessed collection and government-issued IDs.
Disclaimer: This test is for informational purposes. Results should be interpreted by a qualified healthcare professional.
