a Serum CEA levels were determined by an enzyme immunoassay test kit, using a value of 5 ng/ml as positive. CA19.9 was determined using the CA19.9 kit with the suggested value 37 units/ml as positive. Serum CA72-4 antigen levels were determined using the CA72-4 kit with the suggested value 6 units/ml as positive.
