WHAT THE RESULTS MEAN
What if a test is positive or negative?
A High Positive or Positive test result means autoantibodies (how a body responds to cancer) have been detected at an elevated level. Your doctor may recommend additional testing such as imaging to determine if you have lung cancer.
If your result is Low Negative or Negative , your doctor will probably recommend that you continue your regular schedule of testing & examination. A negative test means that none of the antibodies were found above the cutoff level. However, you are still at risk for lung cancer due to your risk factors.
