Symptoms and Testing information for Liquid Bx. Cell-Free EGFR T790ML858R Exon 19 Deletion Test

In the ever-evolving field of genetic testing, one of the most significant advancements has been the development of liquid biopsy (Liquid Bx.) techniques. These innovative methods allow for the non-invasive detection of genetic mutations from circulating tumor DNA (ctDNA) in blood samples. Among these, the Cell-Free EGFR T790M/L858R Exon 19 Deletion Test stands out for its critical role in the diagnosis and management of certain types of cancer. This test, offered by DNA Labs UAE, is a pivotal tool in identifying specific mutations associated with non-small cell lung cancer (NSCLC).

Understanding the EGFR Mutation

The Epidermal Growth Factor Receptor (EGFR) gene is known to play a significant role in the development and progression of various cancers. Mutations in this gene, such as the T790M, L858R, and Exon 19 deletions, are particularly prevalent in non-small cell lung cancer. These mutations lead to abnormal cell growth and division, resulting in the progression of the disease. Detecting these mutations is crucial for the selection of appropriate targeted therapies that can significantly improve patient outcomes.

Symptoms Indicating the Need for the Test

Patients who may benefit from the Cell-Free EGFR T790M/L858R Exon 19 Deletion Test typically exhibit symptoms associated with lung cancer, which include:

  • Persistent cough that does not improve
  • Changes in the voice, such as hoarseness
  • Unexplained weight loss
  • Chest pain or discomfort
  • Shortness of breath
  • Frequent lung infections such as bronchitis or pneumonia

It is important to note that these symptoms can be associated with a variety of conditions, not just lung cancer. However, if you or someone you know is experiencing these symptoms, especially if there is a history of smoking or exposure to lung carcinogens, it is critical to consult a healthcare provider for a comprehensive evaluation, which may include the Cell-Free EGFR T790M/L858R Exon 19 Deletion Test.

The Importance of Early Detection

Early detection of EGFR mutations can significantly impact the treatment strategy and overall prognosis for patients with NSCLC. By identifying these mutations early, healthcare providers can tailor treatments that specifically target the abnormal proteins produced by these genetic alterations. This personalized approach to cancer treatment has been shown to improve response rates, prolong survival, and enhance the quality of life for many patients.

What to Expect from the Test

The Cell-Free EGFR T790M/L858R Exon 19 Deletion Test is a simple, non-invasive procedure that requires only a blood sample. The test is designed to detect the presence of specific EGFR mutations in the ctDNA shed by tumor cells into the bloodstream. This method offers a significant advantage over traditional biopsy techniques, which are more invasive and carry a higher risk of complications.

Test Cost

The cost of the Cell-Free EGFR T790M/L858R Exon 19 Deletion Test at DNA Labs UAE is 3000 AED. While the cost may seem substantial, it is important to consider the potential benefits of early and accurate detection of EGFR mutations, including the possibility of a more favorable outcome through targeted therapy.


The Cell-Free EGFR T790M/L858R Exon 19 Deletion Test represents a significant advancement in the field of cancer diagnostics. For patients with NSCLC, this test offers a non-invasive, accurate, and timely method for detecting critical mutations that can inform treatment decisions and potentially improve outcomes. If you are experiencing symptoms of lung cancer or have been diagnosed with NSCLC, consult your healthcare provider about the possibility of undergoing this test.
