How It Works
Grandparent DNA Testing Explained
A grandparent DNA test compares the DNA of a grandparent with that of a grandchild to determine a biological relationship. You share roughly 25% of your DNA with each biological grandparent. Our AABB accredited lab examines genetic markers from the grandparent and grandchild, then calculates the likelihood of a relationship — returning results that are clear, not vague.
One grandparent is usually enough to reach a conclusion, but testing both grandparents gives stronger, faster results. When both the grandmother and grandfather on the same side are tested, the lab has additional data that significantly strengthens the outcome.

Common Questions
Frequently Asked Questions
How does a grandparent DNA test work if the father is not available?
A grandparent DNA test works by comparing the grandparent’s DNA directly to the grandchild’s DNA. You share roughly 25% of your DNA with each biological grandparent. So when a father is deceased, incarcerated, or unwilling to test, we can still answer the relationship question. Our AABB-accredited lab analyzes genetic markers from the grandparent and grandchild to calculate the likelihood of a biological relationship. One grandparent is often enough, but two gives stronger results.
Do I need to come to a lab location in Columbia to get a grandparent DNA test?
You never need to visit a lab or sit in a waiting room. Odosek Lab Solutions comes directly to you anywhere in Columbia or the Midlands — your home in Shandon, an office near Garners Ferry Road, or a residence in Forest Acres. We collect simple cheek swabs right at your location. Call us at 803-766-0036 to schedule.
Can a grandparent DNA test be used in court in Columbia?
Yes, a grandparent DNA test can absolutely be used in court when it follows strict legal collection protocols. For custody cases, Social Security survivor benefits, and inheritance disputes in Richland County, our results meet all required standards. We follow chain-of-custody procedures on every legal case — ID verification, photography, and tamper-evident packaging.
Is one grandparent enough, or do both need to be tested?
One grandparent is usually enough to reach a conclusion, but testing both grandparents gives a stronger, faster result. When both the grandmother and grandfather on the same side are tested, the lab has additional data to analyze. If you’re unsure, call us — we’ll guide you based on your specific situation.
What are common reasons Columbia families request a grandparent DNA test?
Columbia families use grandparent DNA tests for many reasons — grandmothers in Rosewood preparing for custody hearings, grandfathers near Fort Jackson needing to add a grandchild to military benefits, families dealing with Social Security survivor claims, inheritance disputes, and immigration petitions through USCIS. The most common reason is the father is unavailable to take a standard paternity test.
How long does a grandparent DNA test take from collection to results?
The sample collection itself takes about 15 minutes at your location anywhere in Columbia. After our collector seals the samples and sends them to our AABB accredited lab, results come back in 2–3 business days. We’ll walk you through every line of the report when results arrive.
Odosek Lab Solutions only uses AABB accredited facilities to conduct legal chain-of-custody testing, with scientific experts that ensure genetic testing results you can trust.
