Serum pepsinogen assay by radioimmunoassay is necessary test to diagnostic of the digestive system disease . Assay result is 20-SOng/ml in normal serum, display more than 80ng/ml in patient``s serum. Recovery test is 96-107 percent and dilution test display almost a straight line. In the precision, coefficient of variation of within-assay is 6. 9% in the low level, 4. 8% in the middle level and 3. 5% in the high level. Coefficient of variation of between-assay display 11.7% in the low, 7.4% in the middle and 5.4% in the high level.
