[The determination of immunoreactive gastrin in gastric juice].

A number of conditions should be observed when pretreating gastric juice for gastrin measurements, in order to obtain reliable results. The authors compare the results of gastric juice pretreatment by various methods and the results obtained with the use of different radioimmunoassay kits. Calculation coefficients are suggested, based on the results of computer processing of standard curves. Gastrin concentrations in the blood serum and gastric juice (pretreated and untreated) are compared in the same patients.
