Understanding Lab Tests for Non-Small Cell Lung Cancer
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Non-small cell lung cancer (NSCLC) is typically diagnosed through imaging studies and tissue biopsy. While there is no blood test that can directly diagnose lung cancer, specialized genetic testing plays a fundamental role in treatment planning and determining the most effective therapeutic approach.
Recommended Test
BRAF Mutation Analysis
This genetic test identifies mutations in the BRAF gene that can occur in some cases of non-small cell lung cancer. When present, BRAF mutations contribute to abnormal cell growth and cancer development. Detecting this specific mutation is crucial for determining whether patients may benefit from targeted therapies designed to block the effects of the mutated BRAF protein, leading to more personalized and potentially more effective treatment approaches.

The Role of Genetic Testing in NSCLC Management
Once non-small cell lung cancer has been diagnosed, genetic mutation testing becomes essential for personalizing treatment. These tests help oncologists identify specific genetic changes in cancer cells that can be targeted with precision therapies, potentially improving treatment outcomes and reducing side effects.
Understanding Targeted Therapy
Targeted therapies are medications designed to interfere with specific molecules involved in cancer growth and progression. By identifying genetic mutations like BRAF, healthcare providers can select treatments that are more likely to be effective for each individual patient's specific type of cancer.
Important Considerations
