What is a Paternity DNA Test?
A paternity DNA test determines the biological father of a child by analyzing specific genetic markers. Using advanced STR (Short Tandem Repeat) profiling, the test compares the child's DNA with that of the alleged father and, optionally, the mother. With a 99.99% probability of inclusion and 100% exclusion, this test provides definitive answers for personal, legal, or medical reasons.

| Paternity Nails/ Hair DNA Test | 20,000 | 5–7 | Nails or hair follicles | Discreet testing |
| Swab Self Collection Kit | 1,000 | N/A (kit only) | Buccal swab (self-collected) | For home collection |
How Does the Paternity DNA Test Work?
Our laboratory uses 24-marker or 46-marker STR profiling, which is the gold standard for paternity testing. These markers are highly polymorphic, meaning they vary greatly among individuals, allowing for precise comparison. The process involves:
- Sample Collection: Buccal swabs, blood, or other biological samples are collected at our Visakhapatnam center or via a home collection kit.
- DNA Extraction: DNA is isolated from the cells in the sample.
- PCR Amplification: The specific STR regions are amplified using polymerase chain reaction.
- Fragment Analysis: The amplified fragments are separated and analyzed to determine the number of repeats at each marker.
- Statistical Calculation: The combined paternity index (CPI) is calculated, and the probability of paternity is reported.
For legal cases, a strict chain of custody is maintained, and all samples are collected by a neutral third party to ensure admissibility in court.
Legal vs. Peace of Mind Paternity Test
Understanding the difference is crucial. A legal paternity test is admissible in court and requires a documented chain of custody. A peace of mind test is for personal knowledge only and can be done discreetly at home. Both tests use the same laboratory process and accuracy, but the legal version includes additional documentation and witness verification.

Frequently Asked Questions
How accurate is the paternity DNA test?
The test provides a 99.99% probability of paternity when the alleged father is included, and 100% exclusion when not. This is based on analysis of 24–46 STR markers.
Can I do the test without the mother's sample?
Yes, the test can be performed with just the alleged father and child. Including the mother increases the statistical power but is not mandatory.
How long does it take to get results?
Standard results are available in 3–5 working days. For nails/hair samples, it may take 5–7 working days due to extraction time.
Is the test confidential?
Yes, we adhere to strict confidentiality protocols. Results are shared only with the authorized parties.
