Circulating Free DNA Analysis for Cancer Detection & Treatment Monitoring

Circulating Free DNA Analysis, also known as cfDNA analysis, is a non-invasive diagnostic test that involves analyzing fragments of DNA that are circulating freely in the bloodstream.

These DNA fragments are released from cells in the body, including cancer cells, and can provide valuable information about a person's health status.

In the context of cancer detection, circulating free DNA analysis is particularly useful as it allows for the detection of cancer-related mutations without the need for invasive procedures such as tissue biopsies.

By analyzing these DNA fragments, healthcare providers can identify specific genetic alterations associated with cancer, which can aid in early detection and monitoring of the disease.

Examples of circulating free DNA analysis for cancer detection include the identification of specific mutations in genes such as EGFR, KRAS, and BRAF, which are commonly associated with certain types of cancer.

By analyzing these genetic alterations in the circulating DNA, healthcare providers can tailor treatment plans to target the specific mutations present in the tumor.

Related concepts to circulating free DNA analysis include liquid biopsy, which is a broader term encompassing various tests that analyze biomarkers in bodily fluids such as blood.

Circulating free DNA is one of the biomarkers analyzed in liquid biopsies, along with circulating tumor cells and extracellular vesicles.

What is the Purpose of Performing a Circulating Free DNA Analysis Test?

The primary purpose of performing a circulating free DNA analysis test is to aid in the detection and monitoring of cancer.

By analyzing the genetic alterations present in the circulating DNA, healthcare providers can identify specific mutations associated with cancer and tailor treatment plans accordingly.

The test is particularly useful in non-invasive cancer diagnostics, as it eliminates the need for invasive procedures such as tissue biopsies, which can be painful and carry risks of complications.

Circulating free DNA analysis provides a less invasive alternative for monitoring treatment response and disease progression.

Benefits of circulating free DNA analysis in monitoring treatment response include the ability to track changes in the genetic profile of the tumor over time.

This information can help healthcare providers determine the effectiveness of treatment and make adjustments as needed to improve patient outcomes.

Scenarios where the test is useful include patients with advanced or metastatic cancer who may not be candidates for surgical biopsies.

Circulating free DNA analysis can provide valuable information about the genetic makeup of the tumor without the need for invasive procedures, guiding treatment decisions in these challenging cases.

What are the Costs of Circulating Free DNA Analysis Tests in India?

The costs of circulating free DNA analysis tests in India can vary depending on several factors, including the laboratory performing the test, the complexity of the analysis, and the specific genetic alterations being tested for.

On average, the cost of a circulating free DNA analysis test in India ranges from INR 10,000 to INR 30,000.

Influencing factors that can impact the cost of circulating free DNA analysis tests include the technology used for the analysis, the number of genetic alterations being tested for, and any additional services such as genetic counseling.

It is important for patients to inquire about the total cost of the test and any potential additional charges before proceeding with the analysis.

In comparison to traditional tissue biopsies, circulating free DNA analysis tests may be more cost-effective in certain scenarios, especially in cases where repeated testing is required to monitor treatment response.

The non-invasive nature of circulating free DNA analysis can also help reduce overall healthcare costs by minimizing the need for invasive procedures.

What is the Normal Range and All Values of Circulating Free DNA Analysis?

The normal range of circulating free DNA analysis can vary depending on the specific genetic alterations being tested for and the laboratory performing the analysis.

In general, a normal range for circulating free DNA analysis is considered to be less than 10 ng/mL of blood.
