Paternity DNA Test in Kolkata – Accurate & Legal DNA Testing
A paternity DNA test is the most definitive way to establish a biological relationship between a father and a child. At DNA Labs India, we offer ISO 9001 certified paternity testing in Kolkata with advanced 24-marker and 46-marker STR profiling for unmatched accuracy. Whether you need a legal test for court proceedings or a peace-of-mind test for personal clarity, our lab ensures reliable, confidential, and legally defensible results.
What Is Paternity DNA Testing?
Paternity testing analyzes specific genetic markers (short tandem repeats, or STRs) in a child's DNA to determine if a potential father shares the required genetic pattern. Each person inherits one set of markers from their biological mother and one from their biological father. By comparing these markers between the alleged father and child, we can confirm or exclude paternity with >99.99% accuracy.
How Paternity Testing Works: The Science Behind the Test
Our laboratory uses polymerase chain reaction (PCR) to amplify specific STR loci from the DNA sample. We then perform capillary electrophoresis to determine the number of repeats at each locus. The combined analysis of 24 or 46 markers provides a statistical probability of paternity. This method is the gold standard in forensic and legal DNA testing worldwide.
Types of Paternity DNA Tests Offered
We provide two main categories: Legal Paternity Tests (with chain-of-custody) and Peace-of-Mind Paternity Tests (for personal knowledge). Both use the same high-accuracy STR analysis, but legal tests include a strict sample collection protocol to ensure admissibility in court.
| Test Type | Sample | TAT | Price |
|---|---|---|---|
| Paternity DNA Test | Blood or Buccal Swab | 5–7 days | ₹13,000 |
| Peace of Mind Paternity DNA Test | Buccal Swab (Home Kit) | 5–7 days | ₹13,000 |
| Paternity 1 Father 2 Children DNA Test | Blood or Buccal Swab | 5–7 days | ₹19,500 |
| Paternity Nails/ Hair DNA Test | Nail Clippings or Hair Follicles | 5–7 days | ₹20,000 |
| Swab Self Collection Kit | Buccal Swab (Home Kit) | 5–7 days | ₹1,000 (kit only) |
Sample Collection Methods: Non-Invasive and Convenient
We offer multiple sample collection options to suit your comfort and convenience. All methods are painless and can be performed at home or at our Kolkata center.
| Sample Type | Collection Method | Advantages |
|---|---|---|
| Buccal Swab | Rubbing a sterile swab inside the cheek | Painless, easy, suitable for all ages |
| Blood Sample | Standard venipuncture by trained phlebotomist | High DNA yield, often used for legal tests |
| Nail Clippings | Clipping fingernails or toenails | Non-invasive, can be mailed |
| Hair Follicles | Plucking 5-10 hairs with roots intact | Discreet, suitable for home collection |
Accuracy and Genetic Markers: Why 24 or 46 Markers Matter
Our laboratory analyzes 24 or 46 STR markers, far exceeding the minimum 16 markers used in older tests. This increases the statistical power of the test, ensuring a probability of paternity of 99.99% or higher when included, and 100% exclusion when the alleged father is not the biological father. The use of advanced markers also minimizes the chance of inconclusive results due to rare genetic variants.
Legal vs. Peace-of-Mind Paternity Testing: What’s the Difference?
A legal paternity test follows a strict chain-of-custody protocol: identity verification, witnessed sample collection, and documented handling. This ensures the results are admissible in court for child custody, child support, inheritance, or immigration cases. A peace-of-mind test is for personal knowledge only and can be done discreetly at home with a self-collection kit. Both tests use the same laboratory analysis and accuracy, but only legal tests come with the necessary documentation for legal proceedings.

Frequently Asked Questions (FAQs)
How accurate is the paternity DNA test?
With 24 or 46 STR markers, the test provides a probability of paternity of 99.99% or higher when the alleged father is included, and 100% exclusion when not.
Can I do the test at home?
Yes, we offer a self-collection kit for peace-of-mind tests. You can collect buccal swabs at home and mail them to our lab.
Is the test painful?
No, all sample collection methods are non-invasive or minimally invasive. Buccal swabs and nail/hair samples are completely painless.
How long do results take?
Results are typically available within 5–7 working days after the lab receives all samples.
Is the test legally admissible in court?
Yes, if you opt for a legal paternity test with proper chain-of-custody, the results are admissible in Indian courts.
