CA 15-3 Breast Cancer Marker Test
Understanding the CA 15-3 Breast Cancer Marker Test
The CA 15-3 Breast Cancer Marker Test represents a significant advancement in cancer monitoring and management. This specialized blood test measures the levels of Cancer Antigen 15-3, a protein biomarker that can provide valuable insights into breast cancer activity within the body. While not typically used for initial cancer diagnosis, this test plays a crucial role in tracking treatment effectiveness and detecting potential recurrence in patients with established breast cancer diagnoses.
What Does the CA 15-3 Test Measure?
The CA 15-3 test specifically detects and quantifies the presence of mucin-like glycoprotein antigens in the bloodstream. These antigens are often elevated in individuals with metastatic breast cancer and can serve as important indicators of disease progression or treatment response. The test utilizes sophisticated Chemiluminescent Microparticle Immunoassay technology, ensuring high accuracy and reliability in measurement.

Understanding Your Test Results
Interpreting CA 15-3 test results requires careful consideration of your individual medical history and current health status. Results are typically reported in units per milliliter (U/mL), with normal ranges varying by laboratory.
General Guidance for Results Interpretation:
- Normal Range: Results within the reference range suggest stable disease
- Elevated Levels: May indicate disease progression or treatment resistance
- Trend Analysis: Multiple tests over time provide the most valuable information
- Clinical Correlation: Results should always be interpreted alongside imaging studies and physical examination
- Individual Variation: Normal ranges can vary between individuals
It’s important to discuss your specific results with your oncologist or healthcare provider, who can provide personalized interpretation based on your complete medical picture.
