Improved indirect and direct radioimmunoassay for carcinoembryonic antigen.
Values obtained by the indirect and the direct assays for carcinoembryonic antigen by use of the "CEA Roche" method and reagents differ significantly. In 32 samples the latter method gave values almost twofold those obtained by the former. The mean ratio for direct/indirect was 1.9 +/- 0.6. Analytical recovery experiments on samples to which known amounts of the antigen had been added showed a ...
متن کاملSerum Levels of Carcinoembryonic Antigen and a Tumor-extracted Carcinoembryonic Antigen-related Antigen in Cancer Patients1
Levels of Carcinoembryonic antigen (CEA) and a tumor-ex tracted CEA-related antigen (TEX) were determined in sera from patients with carcinomas of the breast, colon, lung, head and neck, and a number of miscellaneous categories. The purpose of this study was to compare the levels of each antigen at various stages of malignant disease. Competitive radioimmunoassays developed in our laboratory we...

متن کاملDetermination of carcinoembryonic antigen and cancer antigen values with the radioimmunoassay method in healthy females dogs
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 ...
متن کاملRadioimmunoassay of carcinoembryonic antigen in serum of normal subjects and patients with colonic carcinoma.
Sera from 14 normal subjects and 43 patients with colonic carcinoma were evaluated for the presence of carcinoembryonic antigen (CEA). Inhibiting material which behaved in the assay in a similar manner to CEA was found in normal serum at concentrations below 2.8 ng/ml. Its nature has not so far been established. Thirty-eight of the 43 patients with colonic carcinoma showed levels of serum CEA i...
