What Is a Paternity DNA Test?
A paternity DNA test is a highly accurate genetic analysis that determines the biological relationship between a father and a child. It compares specific DNA markers (STRs) from the alleged father and the child to confirm or exclude paternity with 99.99% accuracy. DNA Labs India uses advanced 24-marker and 46-marker STR profiling, exceeding the minimum requirements for legal and personal use.
Why Choose a Paternity Test?
Paternity testing is essential for legal matters (child custody, inheritance, visa applications) and personal peace of mind. DNA Labs India offers both legal and peace-of-mind tests. Legal tests require a strict chain-of-custody process, while peace-of-mind tests can be done discreetly at home.
Types of Paternity Tests Offered
We provide several paternity testing options to suit different needs. All tests use the same high-accuracy STR analysis, but sample collection and legal documentation vary.
| Test Name | Price (₹) | Sample Type | Legal Validity |
|---|---|---|---|
| Paternity DNA Test | 13,000 | Buccal swab or blood | Yes (with chain-of-custody) |
| Peace of Mind Paternity DNA Test | 13,000 | Buccal swab (self-collection) | No (personal use only) |
| Paternity 1 Father 2 Children DNA Test | 19,500 | Buccal swab or blood | Yes (with chain-of-custody) |
| Paternity Nails/ Hair DNA Test | 20,000 | Nail clippings or hair roots | Yes (with chain-of-custody) |
| Swab Self Collection Kit | 1,000 | Buccal swab (home kit) | No (sample collection only) |
How Does the Test Work?
DNA testing analyzes specific short tandem repeat (STR) markers located on different chromosomes. The child inherits one copy from each biological parent. By comparing the alleged father's and child's STR profiles, we can calculate a paternity index and probability of relationship. Our lab uses 24-marker and 46-marker panels, which exceed the international standards for legal paternity testing.
Sample Collection Methods
- Buccal Swab: Painless, non-invasive; rubbing a sterile swab inside the cheek. Ideal for all ages.
- Blood Sample: A small blood draw from the arm; used when legal documentation requires a witnessed collection.
- Nail/Hair: For discreet testing; requires nail clippings or hair with roots. Slightly longer processing time.
Legal vs. Peace-of-Mind Testing
Legal paternity tests follow a strict chain-of-custody: identity verification, witnessed sample collection, and sealed packaging. The results are admissible in Indian courts. Peace-of-mind tests are for personal knowledge only and can be performed at home using our self-collection kit.
