Overview
STR (Short Tandem Repeat) profiling is a molecular genetic technique used to identify individuals by analyzing specific DNA regions that vary in length among people. These regions, called short tandem repeats, are highly polymorphic and serve as unique genetic fingerprints. STR profiling is widely used in forensic science for crime scene investigation, in paternity testing to establish biological relationships, and in disaster victim identification. At DNA Labs India, we offer accurate and reliable STR profiling at an affordable cost of INR 6500. Our laboratory follows strict quality control measures and is NABL accredited, ensuring precise results. The test requires a simple DNA sample, which can be collected via a buccal swab or blood sample. With free home sample collection available across major cities in India, we make the process convenient and accessible. Whether you need STR profiling for legal purposes, personal peace of mind, or forensic analysis, our expert team ensures confidentiality and accuracy. Understanding your genetic identity has never been easier or more affordable.

The primary purpose of STR profiling is to generate a unique DNA profile for an individual. This profile can be used for: 1) Forensic identification – matching crime scene evidence to suspects or victims. 2) Paternity testing – confirming biological father-child relationships. 3) Immigration cases – proving family relationships for visa applications. 4) Missing person identification – helping in disaster victim identification. 5) Genetic genealogy – tracing ancestry and family history. 6) Legal disputes – resolving inheritance or custody cases. STR profiling provides conclusive evidence with a high degree of accuracy, making it an indispensable tool in modern medicine and law.

Questions customers ask
Frequently asked questions
What is STR profiling?
STR profiling is a DNA testing method that analyzes specific short tandem repeat regions in the genome to create a unique genetic fingerprint for an individual. It is used for forensic identification, paternity testing, and other applications.
How much does STR profiling cost in India?
At DNA Labs India, STR profiling costs INR 6500, which includes sample collection, analysis, and reporting. We offer free home sample collection across many cities in India.
What sample is required for STR profiling?
A simple buccal swab (cheek swab) or a blood sample is required. The sample is collected using a sterile kit, and the DNA is extracted for analysis.
How long does it take to get STR profiling results?
Results are typically available within 10 days after the sample reaches the laboratory. You will receive the report via email, WhatsApp, or online portal.
Is fasting required before STR profiling?
No, fasting is not required. However, for buccal swab collection, it is recommended to avoid eating, drinking, or smoking for 30 minutes before the test.
Can STR profiling be used for legal purposes?
Yes, STR profiling is widely accepted in legal cases such as paternity disputes, inheritance claims, and criminal investigations. For legal validity, the test must be performed with proper chain of custody and at an accredited laboratory.
Is home sample collection available for STR profiling?
Yes, DNA Labs India offers free home sample collection for online bookings in over 200 cities across India, including Mumbai, Delhi, Bangalore, Hyderabad, and more.
What is the accuracy of STR profiling?
STR profiling is highly accurate, with a probability of paternity of 99.99% or higher when the alleged father is included. The probability of a random match is extremely low, typically less than 1 in a billion.
Can STR profiling determine the sex of an individual?
Yes, STR profiling includes the Amelogenin locus, which indicates the presence of X and Y chromosomes. This can determine the biological sex of the individual.
Are there any risks associated with STR profiling?
The test is non-invasive and carries minimal risk. For blood collection, there is a slight risk of bruising or infection at the puncture site. Buccal swab is completely safe.
How should I prepare for the STR profiling test?
No special preparation is needed. If you are providing a buccal swab, avoid eating, drinking, or chewing gum for 30 minutes before collection. For blood sample, no preparation is required.
Will my insurance cover the cost of STR profiling?
STR profiling is typically not covered by insurance as it is often used for legal or personal purposes. However, you may check with your insurance provider for possible coverage in specific medical situations.
