DNA Siblingship Test: Confirming Biological Relationships in Kenya
A DNA Siblingship Test is a sophisticated genetic analysis used to determine whether two individuals share one or both biological parents. This test is essential when the alleged father or mother is unavailable for direct testing. At Zote, we provide discreet, accurate, and professional genetic services to help you find the answers you need.
Labtest Zote is a KMLTTB licensed laboratory, ensuring that all samples are handled under strict clinical protocols and ethical standards within the Kenyan healthcare framework.
Why Take a DNA Siblingship Test?
People typically seek a siblingship test for various personal or legal reasons, including:
- Inheritance Claims: Establishing biological links for estate settlement.
- Immigration: Proving family relationships for visa applications.
- Peace of Mind: Resolving long-standing questions about family identity.
- Alternative to Paternity Testing: When the father is deceased or unwilling to test, his children can be tested against each other to determine if they share the same paternal line.
How It Works: The Science of Kinship
Unlike a paternity test (which looks for a 50% genetic match), siblingship testing uses complex statistical analysis known as the Siblingship Index. By comparing the genetic markers (loci) of two individuals, we calculate the likelihood that they are full siblings, half-siblings, or unrelated.
Test Specifications and Reference Ranges
The results are presented as a probability percentage based on the Likelihood Ratio.
| Relationship Type | Probability of Relationship | Interpretation |
| Full Siblings | > 90% | Highly likely they share both parents. |
| Half Siblings | > 90% | Highly likely, they share one parent. |
| Unrelated | < 10% | Unlikely to be biologically related. |
Note: For the highest accuracy, we recommend including a known parent’s sample (e.g., the mother) if available. This helps “filter” the genetic data to focus more clearly on the shared paternal or maternal genes.
Important Instructions for Your Test
To ensure the integrity of your genetic sample, please follow these guidelines:
- Fasting: No fasting is required for this test.
- Sample Collection: We use a non-invasive buccal swab (saliva/cheek swab). It is painless and takes less than a minute.
- Preparation: Avoid eating, drinking coffee, or smoking for 30 minutes before the swab collection to prevent sample contamination.
- Documentation: Please bring a valid National ID, Passport, Refugee Status, Birth Certificate, or any other valid identification document for all parties being tested.
