Additional tumor marker testing revealed an elevated cancer antigen 125 (CA 125) level of 94.5 kU/L (normal up to 35 kU/L), slightly elevated cancer antigen 19-9 (CA 19-9) level of 42.4 kU/L (normal up to 37), and carcinoembryonic antigen (CEA) level of 6.2 kU/L (normal up to 4.2 kU/L), while alpha-fetoprotein (AFP) levels were within normal limits. This evidence concerns the gene AFP and neoplasm.
