Overview
RNA extraction from plasma or serum is a fundamental procedure in molecular diagnostics, enabling the isolation of circulating RNA molecules that carry genetic information essential for protein synthesis and regulation. This test is pivotal for identifying and quantifying gene expression, detecting mutations, and diagnosing viral infections directly from blood samples. At DNA Labs India, we utilize state-of-the-art equipment and validated protocols to ensure high-quality RNA extraction, which is the cornerstone for accurate downstream applications such as RT-PCR, sequencing, and gene expression profiling. Our experienced professionals adhere to stringent quality controls to deliver reliable results, supporting clinicians in early diagnosis, disease monitoring, and therapeutic decision-making. The test is performed on either plasma or serum, depending on the clinical requirement, and is available at a cost of INR 3000. With free home sample collection across major cities in India, we aim to make advanced molecular testing accessible and convenient. Whether for diagnosing infectious diseases like HIV, hepatitis, and Zika, or for monitoring cancer biomarkers, RNA extraction from plasma or serum is a valuable tool in modern medicine.

The primary purpose of RNA extraction from plasma or serum is to isolate high-quality RNA for downstream molecular analysis. This includes detecting viral RNA (e.g., HIV, hepatitis C, Zika), quantifying gene expression, identifying mutations associated with cancer, and monitoring disease progression or treatment response. By providing a pure RNA sample, this test enables accurate and sensitive detection of biomarkers, facilitating early diagnosis and personalized treatment strategies.

Frequently asked questions
What is RNA extraction from plasma or serum?
RNA extraction is a laboratory process to isolate RNA molecules from blood plasma or serum. This RNA can be used for detecting viruses, gene expression, and mutations.
Why is RNA extraction important?
RNA extraction is crucial for accurate molecular diagnosis, as it provides the template for tests like RT-PCR, which detect viral infections and genetic abnormalities.
What is the cost of RNA extraction at DNA Labs India?
The cost is INR 3000, which includes home sample collection and the extraction procedure.
Do I need to fast for this test?
No, fasting is not required for RNA extraction from plasma or serum.
What sample is needed?
A blood sample is collected in either an EDTA tube (for plasma) or a serum separator tube (for serum).
How long does it take to get results?
Reports are typically available within 1 week after sample collection.
Is home sample collection available?
Yes, we offer free home sample collection for online bookings across many cities in India.
What diseases can be diagnosed using RNA extraction?
It can help diagnose HIV, hepatitis B and C, Zika virus, and certain cancers by detecting viral RNA or gene expression biomarkers.
Can RNA extraction be used for monitoring treatment?
Yes, it is used to monitor viral load and treatment response in chronic infections and cancers.
What is the difference between plasma and serum for RNA extraction?
Plasma is obtained from blood with an anticoagulant, while serum is from clotted blood. Both contain cell-free RNA, but the choice depends on the test requirement.
Are there any risks associated with the test?
The test involves a simple blood draw, which carries minimal risks like slight bruising or dizziness.
How should I prepare for the test?
No special preparation is needed. Inform your doctor about any medications you are taking.
