Overview
DNA extraction from a buccal swab or filter paper is a laboratory procedure used to isolate deoxyribonucleic acid (DNA) from cells collected on the inside of the cheek or from dried blood spots on filter paper. This extracted DNA serves as the starting material for various genetic tests, including paternity testing, carrier screening, pharmacogenomics, and diagnosis of inherited disorders. At DNA Labs India, we use validated, high-yield extraction methods to ensure the integrity of the genetic material. The test is non-invasive, painless, and can be performed on individuals of all ages, including infants. Our laboratory follows strict quality control measures to prevent contamination and degradation, ensuring accurate downstream analysis. The cost of the test is INR 1800, which includes the collection kit, home sample collection (in select cities), and the extraction procedure. Results are typically available within 5-7 business days. This service is ideal for patients who require genetic testing but prefer a convenient, at-home sample collection option.

The primary purpose of DNA extraction is to obtain pure, high-quality DNA from a biological sample for subsequent genetic analysis. This may be needed for: 1) Confirming a suspected genetic disorder, 2) Determining biological relationships (paternity/maternity), 3) Assessing genetic predisposition to certain diseases, 4) Guiding personalized treatment (pharmacogenomics), 5) Carrier screening for inherited conditions, 6) Forensic or legal identification. The extracted DNA can be used for PCR, sequencing, microarray, or other molecular assays.

How long does it take to get results?
Results are typically available within 5-7 business days after the sample reaches our laboratory.
What is the sample type for this test?
The sample type is a buccal swab (from the inside of the cheek) or filter paper (dried blood spot).
Is the test painful?
No, the test is completely painless. You may feel a slight rubbing sensation during collection.
Can this test be done on infants?
Yes, buccal swab collection is safe for infants and children. It is a non-invasive method.
What is the purpose of DNA extraction?
The purpose is to obtain pure DNA for downstream genetic testing, such as paternity testing, carrier screening, or diagnosis of genetic disorders.
Are there any risks associated with the test?
No significant risks. Minor discomfort or gagging may occur in some individuals, but it is temporary.
How should I store the sample after collection?
Keep the swab in the provided transport tube and store at room temperature. Avoid exposure to heat or moisture. Ship it to the lab within 7 days.
