The galactosidase immunosorbent test for carcinoembryonic antigen is simple to perform, uses stable reagents, does not require radioactive reagents, and is adaptable to large numbers of samples. Concentration of carcinoembryonic antigen in sera or plasma was determined by the galactosidase immunosorbent test and by the Egan-Todd double antibody assay (93% agreement), indirect Z-gel (83% agreeme...

OBJECTIVE We prospectively tested whether circulating tumor cells can be found in the preoperative, intraoperative, and postoperative peripheral blood of patients with resectable non-small cell lung cancer who undergo video-assisted lobectomy. METHODS We assayed for carcinoembryonic antigen messenger RNA (mRNA) by reverse transcriptase-polymerase chain reaction in the peripheral blood taken b...

The aim of this study was to determine reference values of carcinoembryonic antigen and cancer antigen in 32 clinically healthy bitches. The average age of the bitches in each group was as follows: small breeds 3.50 ± 2.30, medium breeds 3.83 ± 3.21, large breeds 6.00 ± 3.22 and giant breeds 2.40 ± 2.43. The average weight in each group was as follows: 1st group 7.94 kg ± 1.84, 2nd group 22.38 ...
