Understanding Cyfra (Ca) 21-1
CYFRA 21-1 is a fragment of cytokeratin 19, a structural protein present in epithelial cells, including lung tissue. When lung cells are damaged or undergo malignant changes, fragments of cytokeratin 19 are released into the blood. Elevated CYFRA 21-1 levels may indicate the presence of lung cancer, especially non-small cell lung cancer, and can also help monitor response to treatment or detect recurrence after therapy. The Cyfra (Ca) 21-1 test measures the level of this protein fragment in the blood and is mainly...
