Overview
The Paternal Lineage Y-STR Test is a specialized genetic analysis that examines the Y-chromosome, which is passed down from father to son with minimal changes across generations. This test is used to determine whether two or more males share a common paternal ancestor, making it valuable for genealogical research, family relationship verification, and anthropological studies. At DNA Labs India, we offer this test at an affordable cost of INR 24000, with free home sample collection across major cities in India. The test is non-invasive, requiring only a simple cheek swab or blood sample. Our state-of-the-art laboratory ensures high accuracy and confidentiality, with results typically available within 10 days. Whether you are exploring your ancestry or need to confirm a biological relationship, this test provides reliable insights into your paternal lineage.

The primary purpose of the Y-STR test is to establish whether two or more males are related through their paternal line. Since the Y-chromosome is inherited virtually unchanged from father to son, males sharing a common paternal ancestor will have identical or near-identical Y-STR profiles. This test is commonly used to confirm father-son relationships, paternal half-brothers, paternal uncle-nephew relationships, grandfather-grandson relationships, and paternal cousins. It is also useful in cases where the alleged father is unavailable for testing, by comparing the Y-STR profile of the child with that of a known paternal male relative. The test can also provide information about the individual's haplogroup, which indicates deep ancestral origins and migration patterns.

Frequently asked questions
What is the cost of the Paternal Lineage Y-STR Test?
The cost is INR 24000, which includes free home sample collection across India.
How is the Y-STR test different from a paternity test?
A paternity test typically uses autosomal DNA markers to establish a father-child relationship, while the Y-STR test specifically examines the Y-chromosome to trace paternal lineage and can be used for extended family relationships.
Can the Y-STR test determine the exact relationship between two males?
No, the test can confirm whether two males share a paternal line, but it cannot specify the exact relationship (e.g., father vs. brother). Additional testing or family history may be needed.
What sample is required for the Y-STR test?
A buccal swab (cheek swab) or a blood sample (EDTA tube or FTA card) is required. Buccal swabs are non-invasive and preferred.
How long does it take to get results?
Results are typically available within 10 working days after the sample is received at the laboratory.
Is fasting required before the test?
No, fasting is not required. However, for buccal swabs, avoid eating, drinking, or smoking for 30 minutes before collection.
Can the test be done for a child?
Yes, the test can be performed on males of any age, including children. For minors, consent from a parent or guardian is required.
Is the test confidential?
Yes, DNA Labs India follows strict confidentiality protocols. Results are shared only with the authorized individuals.
Can the Y-STR test be used for legal purposes?
Yes, if a strict chain of custody is maintained, the results can be used for legal purposes such as inheritance disputes or immigration cases.
What is a haplogroup?
A haplogroup is a group of people who share a common ancestor on the paternal line, identified by specific Y-chromosome mutations. It can indicate deep ancestral origins and migration patterns.
Are there any risks associated with the test?
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.
Can the test be done if the alleged father is not available?
Yes, the test can be performed by comparing the Y-STR profile of the child with that of a known paternal male relative, such as a paternal uncle or grandfather.
