The CYFRA 21-1 test result is a significant indicator in the diagnosis and monitoring of lung cancer. This article provides detailed information about the CYFRA 21-1 index, the meaning of different levels, and important considerations when interpreting test results.
What is CYFRA 21-1?
CYFRA 21-1 is a type of protein found in the blood. CYFRA 21-1 levels are often elevated in individuals with lung cancer, particularly non-small cell lung cancer. However, this index can also increase in other conditions such as pneumonia, pulmonary fibrosis, and certain other cancers. Therefore, CYFRA 21-1 test results should be evaluated in conjunction with other tests and clinical symptoms to reach an accurate diagnosis.
Understanding Your CYFRA 21-1 Test Results
Normal CYFRA 21-1 levels are typically below 3.3 ng/mL. However, this threshold may vary slightly depending on the laboratory.
- Elevated CYFRA 21-1: A high CYFRA 21-1 level may indicate lung cancer, especially non-small cell lung cancer. However, it is not a definitive diagnosis. Elevated levels can also occur in other conditions such as chronic obstructive pulmonary disease, tuberculosis, and certain other cancers.
- Low CYFRA 21-1: Low CYFRA 21-1 levels are generally considered normal and are less likely to be associated with lung cancer.
When is a CYFRA 21-1 Test Needed?
A CYFRA 21-1 test is usually ordered in the following situations:
- Lung Cancer Diagnosis: In combination with other tests, CYFRA 21-1 helps doctors assess the likelihood of lung cancer.
- Monitoring Lung Cancer Treatment: Regular testing helps monitor treatment effectiveness and detect early recurrence.
- Lung Cancer Prognosis Assessment: CYFRA 21-1 levels can help predict the prognosis of the disease.
Important Considerations When Interpreting CYFRA 21-1 Results
- CYFRA 21-1 test results should be evaluated and interpreted by a specialist physician.
- Do not self-diagnose based on test results alone.
- CYFRA 21-1 test results should be combined with other tests and clinical symptoms for an accurate diagnosis.
Conclusion
The CYFRA 21-1 test result is a useful tool in the diagnosis and monitoring of lung cancer. However, it is not the sole determinant. Combining it with other tests and clinical assessments is essential for accurate diagnosis and appropriate treatment. Contact your doctor for specific advice regarding your situation.
