What is a DNA Test?
A DNA test analyzes your genetic material to identify relationships, genetic predispositions, or hereditary conditions. For paternity testing, it compares specific DNA markers between a child and alleged father to confirm biological relationship with >99.99% accuracy.
How Does DNA Testing Work?
Modern DNA testing uses Short Tandem Repeat (STR) profiling with 24 to 46 markers. Each marker is a specific location on your DNA that varies between individuals. By comparing these markers, we can determine if a biological relationship exists.
For advanced genomic analysis (e.g., hereditary cancer risk), we use Next-Generation Sequencing (NGS) and Whole Exome Sequencing (WES) to detect mutations across thousands of genes.
Types of DNA Tests Offered
- Paternity DNA Test – Confirms biological father-child relationship.
- Peace of Mind Paternity Test – For personal knowledge, not legal use.
- Paternity 1 Father 2 Children Test – Tests two children with one alleged father.
- Paternity Nails/Hair DNA Test – Uses non-standard samples like nails or hair roots.
- Swab Self Collection Kit – Collect samples at home and mail them to our lab.
Sample Collection Methods
We offer two primary collection methods:
- Buccal Swab – A painless cotton swab rubbed inside the cheek. No fasting required.
- Blood Sample – A small blood draw from the arm. No fasting required.
For at-home collection, our Swab Self Collection Kit provides everything needed.
Step-by-Step Test Procedure
- Sample Collection – Buccal swab or blood sample is taken from all participants.
- DNA Extraction – The lab isolates DNA from the cells.
- STR Amplification – Specific markers are amplified using PCR.
- Marker Analysis – The number of repeats at each marker is measured.
- Comparison & Report – Profiles are compared to calculate a probability of relationship.
Turnaround Time and Results
Standard results are available in 5–7 business days after samples reach the lab. For urgent cases, expedited processing may be available on request.
Cost of DNA Tests
Below is the current pricing for our DNA tests. All prices are in INR and include GST.
| Test Name | Price | TAT |
|---|---|---|
| Paternity DNA Test | ₹13,000 | 5–7 days |
| Peace of Mind Paternity DNA Test | ₹13,000 | 5–7 days |
| Paternity 1 Father 2 Children DNA Test | ₹19,500 | 5–7 days |

Accuracy and Reliability
Our paternity tests provide 99.99% accuracy for inclusions and 100% exclusion probability. We use validated STR markers and follow strict chain-of-custody protocols for legal cases.
Legal vs Peace of Mind Tests
Legal DNA tests require a chain-of-custody process, including identity verification and witnessed sample collection. Peace of mind tests are for personal knowledge only and cannot be used in court.
