What is a Paternity DNA Test?
A paternity DNA test is a highly accurate genetic analysis that determines the biological father of a child. By comparing specific DNA markers (short tandem repeats or STRs) between the child and the alleged father, the test provides a probability of paternity exceeding 99.99% when included, and 100% when excluded. DNA Labs India uses advanced 24-marker STR profiling to ensure reliable and court-admissible results.
Types of Relationship DNA Tests
DNA Labs India offers a comprehensive range of relationship DNA tests to establish biological connections. These include:
- Maternity DNA Test – Confirms the biological mother of a child.
- Sibling DNA Test – Determines if two individuals share one or both biological parents.
- Avuncular DNA Test – Establishes if an individual is the biological aunt or uncle of a child.
- Grandparent DNA Test – Confirms the biological relationship between grandparents and a grandchild.
How Does Paternity DNA Testing Work?
The test analyzes 24 specific STR markers located on different chromosomes. These markers are highly variable among individuals, making them ideal for identification. DNA is extracted from the collected samples (blood or buccal swabs), amplified using polymerase chain reaction (PCR), and then separated by capillary electrophoresis. The resulting DNA profiles are compared to calculate a paternity index and a combined paternity index (CPI). A CPI of 100 or higher is considered strong evidence of paternity.
Sample Collection and Preparation
Sample collection is simple and painless. For a standard paternity test, we collect blood samples or buccal swabs from the child and the alleged father. Buccal swabs are non-invasive and involve rubbing a sterile cotton swab on the inside of the cheek. No fasting or special preparation is required. Samples can be collected at any of our collection centers across India, or via our at-home collection kit with clear instructions.
Test Accuracy and Markers
Our paternity test uses 24 STR markers, exceeding the minimum 16 markers recommended by international guidelines. This high-resolution approach ensures an accuracy of 99.99% for inclusions and 100% for exclusions. All tests are performed in our ISO 9001 certified laboratory, following strict quality control protocols to prevent contamination and ensure reproducible results.
Cost and Turnaround Time
The cost of a paternity DNA test at DNA Labs India is ₹13,000 INR. This includes sample collection, analysis, and a detailed report. Results are typically delivered within 5 working days. For urgent needs, expedited processing is available at an additional cost. Contact our helpline for current pricing and any ongoing discounts.
