Diagnosis of Non-Small Cell Lung Cancer

Laboratory Evaluation in Non-Small Cell Lung Cancer

The following additional laboratory studies are helpful in the diagnosis, staging, and later management of lung cancer:

• Sputum cytology - A sample of sputum (phlegm) is examined under the microscope to detect cancer cells. This test only identifies about 25% of lung cancer cases.
• Complete blood count
• Liver Function Tests (LFTs)
• Blood chemistries
• Platelet count
