Overview
DNA extraction from plasma or serum is a fundamental procedure in molecular diagnostics, enabling the isolation of cell-free DNA (cfDNA) or circulating tumor DNA (ctDNA) for various clinical applications. At DNA Labs India, we utilize advanced extraction technologies to ensure high-quality DNA suitable for downstream analyses such as PCR, sequencing, and genotyping. This test is essential for detecting genetic mutations, monitoring treatment response, and screening for infectious agents. Our laboratory adheres to strict quality control measures, ensuring reliable and reproducible results. With a cost of INR 1800, we provide an affordable solution without compromising on accuracy. Our experienced professionals handle samples with utmost care, and we offer free home sample collection across multiple cities in India for your convenience. The extracted DNA is rigorously assessed for quantity and purity, ensuring optimal performance in subsequent molecular assays. Whether for research or clinical purposes, our service meets the highest standards of quality and reliability.

The primary purpose of DNA extraction from plasma or serum is to obtain purified DNA for molecular testing. This includes identifying genetic mutations associated with hereditary disorders, detecting oncogenic mutations in cancer patients (liquid biopsy), monitoring minimal residual disease, and diagnosing infectious diseases by detecting pathogen DNA. The extracted DNA can be used for various applications such as next-generation sequencing, real-time PCR, and microarray analysis. Early detection and precise diagnosis facilitated by this test can guide treatment decisions and improve patient outcomes.

Questions customers ask
Frequently asked questions
What is DNA extraction from plasma or serum?
It is a laboratory process to isolate DNA from the cell-free fraction of blood (plasma or serum) for molecular testing.
Why is this test needed?
It is used for detecting genetic mutations, diagnosing infections, and monitoring cancer treatment response.
Is fasting required before the test?
No, fasting is not required for DNA extraction from plasma or serum.
What sample is needed?
A blood sample collected in an EDTA tube (for plasma) or SST (for serum).
How long does the test take?
The turnaround time is 5 days.
Is home sample collection available?
Yes, we offer free home sample collection for online bookings across many cities in India.
What is the cost of the test?
The cost is INR 1800, which is all-inclusive with no hidden charges.
Are there any risks associated with the test?
The test involves a simple blood draw, which carries minimal risks like slight bruising or infection.
Can this test detect cancer?
It can detect circulating tumor DNA, which may indicate the presence of cancer, but it is not a standalone diagnostic test.
How should the sample be stored?
Plasma or serum should be stored at 2-8°C if processed within 24 hours, otherwise frozen at -20°C.
What is the difference between plasma and serum?
Plasma is the liquid component of blood containing anticoagulants, while serum is the liquid remaining after blood clotting. Both can be used for DNA extraction.
Will I get a report?
Yes, you will receive a detailed report with DNA quantity and purity, which can be accessed online or via email.
