Mid America Clinical Laboratories, the largest clinical laboratory in Indiana, will begin offering EarlyCDT-Lung, a blood test designed to help diagnose lung cancer early on. EarlyCDT-Lung checks whether the patient has antibodies (immune system components) associated with a number of tumor-related proteins. High levels of such antibodies suggest that cancer may be present. EarlyCDT is highly accurate and specific for lung cancer, is less likely than computed tomography (CT) scans to falsely detect cancer when none is present, and can detect cancer-related antibodies up to 5 years before a tumor can be found using other screening methods. Such early detection is vital because lung cancer survival rates are higher when the disease is diagnosed at an early stage.
