CA CYFRA 21-1 Lung Cancer Marker Test
Comprehensive Lung Cancer Detection and Monitoring
The CA CYFRA 21-1 Lung Cancer Marker Test represents a significant advancement in pulmonary oncology diagnostics. This specialized blood analysis measures cytokeratin 19 fragments, which serve as crucial biomarkers for various forms of lung cancer, with particular sensitivity for non-small cell lung cancer (NSCLC). As lung cancer remains one of the most prevalent and deadly cancers worldwide, early detection through reliable biomarker testing becomes increasingly vital for improving patient outcomes and survival rates.
What Does the CA CYFRA 21-1 Test Measure?
The CA CYFRA 21-1 test specifically detects and quantifies fragments of cytokeratin 19, a structural protein found in epithelial cells. When lung tissue becomes malignant, these cytokeratin fragments are released into the bloodstream at elevated levels. The test utilizes advanced electrochemiluminescence technology to provide precise measurements, offering healthcare providers valuable data for:
- Early detection of lung malignancies
- Monitoring treatment effectiveness
- Tracking disease progression or recurrence
- Differentiating between lung cancer types
Who Should Consider This Test?
This test is particularly recommended for individuals experiencing persistent symptoms or having risk factors associated with lung cancer, including:
- Persistent cough lasting more than 3 weeks
- Unexplained weight loss and fatigue
- Chest pain or discomfort
- Shortness of breath or wheezing
- History of smoking or tobacco use
- Family history of lung cancer
- Exposure to environmental carcinogens
- Previous abnormal chest imaging results
Key Benefits of CA CYFRA 21-1 Testing
Choosing the CA CYFRA 21-1 test provides numerous advantages for both patients and healthcare providers:
- Early Detection Capability: Identifies potential lung cancer at earlier, more treatable stages
- Treatment Monitoring: Helps assess how well current treatments are working
- Progression Tracking: Monitors disease development over time
- Non-Invasive Procedure: Simple blood draw with minimal discomfort
- Quick Results: Turnaround time of approximately one week
- High Accuracy: Advanced electrochemiluminescence technology ensures reliable results
Understanding Your Test Results
Interpreting CA CYFRA 21-1 results requires professional medical expertise, but general guidelines include:
- Normal Range: Typically below 3.3 ng/mL, though reference ranges may vary
- Elevated Levels: May indicate lung cancer presence or progression
- Treatment Response: Decreasing levels often suggest positive response to therapy
- Disease Monitoring: Rising levels may indicate recurrence or progression
It’s important to note that elevated CA CYFRA 21-1 levels can occur in other conditions, and normal levels don’t completely rule out lung cancer. Always discuss results with your oncologist or chest physician for proper interpretation.
