Cyfra 21-1
Cyfra 21-1
Cyfra 21-1 is used as a tumour marker for the monitoring and management of non-small cell lung cancer (NSCLC). This test measures the levels of Cyfra 21-1, a protein fragment derived from cytokeratin 19 (filaments found in the epithelial cells). It is important to note that Cyfra 21-1 should not be solely relied upon for diagnosing lung cancer, but rather used in conjunction with other tests and clinical evaluations. It is recommended to undergo this test as it provides valuable information about the stage of the disease, the effectiveness of the treatment, and the monitoring of post-treatment recurrence
