The requirement for gastrin measurements.

O Jacobsen, L Bardram, J F Rehfeld

    Scandinavian Journal of Clinical and Laboratory Investigation
    |September 1, 1986
    PubMed
    Summary

    Gastrin measurements are crucial for diagnosing Zollinger-Ellison syndrome and other gastrointestinal disorders. Approximately 200 gastrin tests per million people annually are needed for effective clinical management and diagnosis.

    Area of Science:

    • Endocrinology
    • Gastroenterology
    • Clinical Chemistry

    Background:

    • Gastrin measurements are essential for diagnosing and managing conditions like Zollinger-Ellison syndrome.
    • Assessing the clinical utility of gastrin testing is important for healthcare resource planning.

    Purpose of the Study:

    • To evaluate the clinical demand for gastrin measurements in a large population.
    • To determine the necessary frequency of gastrin assays for diagnosing gastrinomas and other conditions.

    Main Methods:

    • Retrospective analysis of 1392 gastrin measurements from 931 patients over 1.5 years.
    • Radioimmunoassay (RIA) used to quantify bioactive gastrins.
    • Analysis of patient data to identify causes of hypergastrinemia.

    Main Results:

    • Elevated gastrin levels were found in 121 patients, with 19 known Zollinger-Ellison syndrome (ZES) patients.
    • Gastrin testing suggested gastrin-producing tumors in 11 previously undiagnosed patients (4 with ZES).
    • Secondary hypergastrinemia was observed in 75 patients due to other gastrointestinal diseases.

    Conclusions:

    • Diagnosis, localization, and therapy control of gastrinomas necessitate approximately 200 gastrin measurements per million inhabitants annually.
    • This data can inform the planning of gastrin assay services.
