A member asked:
I took a early cdt lung blood tests and the mage a 4 was the only one slightly elevated what does that mean?
A doctor has provided 1 answer
Review all findings: Earlycdt-lung test looks for autoantibodies (antibodies one makes against substances [antigens] in her own body) that are more often found in lung cancer patients, and seldom in normal people. The mage a4 is one of many antigens whose autoantibodies are measured by the test. The doctor who ordered the test looks at all the results plus the symptoms and physical exam, before deciding what it means.
