The blood test results showed negative tumor markers (alpha-fetoprotein [AFP], carcinoembryonic antigen [CEA], carbohydrate antigen 19-9 [CA19-9], soluble interleukin-2 receptor [sIL-2R]), nor markers associated with multiple myeloma (immunoglobulin [Ig] G, A, M, urinary Bence-Jones protein). The gene discussed is AFP; the disease is neoplasm.
