A CYFRA 21-1 test measures the level of a specific protein fragment called Cytokeratin 19 in the blood. Cytokeratins are structural proteins that provide support to epithelial cells (cells that line the surfaces of your body).
When certain types of lung cancer cells grow and die, they release these fragments into the bloodstream, making CYFRA 21-1 a valuable tumor marker.
