DNA Siblingship Test (Brother/Sister DNA Test)

⭐ Private • Accurate • Convenient
The DNA Siblingship Test helps determine whether two individuals are biologically related as
siblings (either full siblings or half-siblings). It’s especially helpful when a parent is unavailable
for direct testing. Samples are collected using painless cheek swabs at home, returned for
laboratory analysis, and results are shared securely via WhatsApp or email.

⭐ Why Choose This Test?
• Confirms sibling relationships when paternity/maternity testing isn’t possible
• Non-invasive cheek swab — safe for children and adults
• Accurate laboratory DNA analysis with probability-based results
• Private home collection and discreet handling
• Useful for family clarity, documentation needs, and peace of mind
Tip for stronger accuracy: If a known parent (often the mother) can be included, it can improve
clarity in some cases by helping the lab interpret shared DNA more confidently.

⭐ What This Test Detects (Granular)
Siblingship Probability (Full Siblings vs Half Siblings vs Unrelated)
This test compares multiple DNA markers between two people and calculates how likely they
are to be biologically related.
Your report typically includes:
Siblingship Index (Likelihood Ratio / LR)
A statistical value showing how strongly the DNA supports a sibling relationship versus being
unrelated.
Probability of Relationship (%)
A percentage estimate that helps interpret the likelihood of:
 Full siblings (share both parents)
 Half siblings (share one parent)
 Unrelated (no biological sibling relationship detected)

⭐ How to Prepare for the Test
• No fasting required
• Avoid eating, drinking, chewing gum, smoking, or brushing teeth for 30 minutes before
swabbing
• Wash hands before collecting samples
• Ensure each person uses the correct labeled swab and packaging
⚠️ Medication note: Do not stop or change any medication unless advised by a qualified
healthcare professional.
