Overview
Autosomal STR (Fragment Analysis) is a highly accurate DNA testing method used to establish biological relationships between individuals, such as paternity, maternity, and siblingship. It analyzes short tandem repeats (STRs) on autosomal chromosomes, which are unique genetic markers inherited from both parents. This test is widely recognized for its reliability in legal, immigration, and inheritance dispute cases. At DNA Labs India, we offer this test at an affordable cost of INR 15,000, with results delivered within 10-15 business days. The process involves collecting a DNA sample, typically via a buccal swab or blood draw, and analyzing it using advanced fragment analysis technology. Our laboratory ensures high accuracy and confidentiality, making it a trusted choice for relationship testing across India. The test examines multiple STR loci to provide a statistical probability of relationship, ensuring robust and court-admissible results. Additionally, we provide comprehensive support and consultation to guide you through the testing process and interpretation of results. Our state-of-the-art laboratory uses the latest technology to ensure precise and reliable outcomes. We adhere to strict quality control measures and international standards to maintain the highest level of accuracy. Whether for personal knowledge or legal purposes, our Autosomal STR test provides definitive answers with a high degree of certainty.
