30 healthy controls. After taking peripheral blood samples and extracting total RNA, cDNA
was synthesized and examined by Real-time RT-PCR technique. Then, the CEA antigen
was measured by ELISA. Results: The CK19mRNA was positive in 7 out of 30 lung cancer
patients. Hence, its sensitivity was determined to be 23.3%. The serum level of CEA antigen
was positive in 11 out of 30 lung cancer patients. The mean serum level of CEA antigen …
