A Simple Precipitin Test for Corticosteroid-Binding Globulin: Use in a Search for the Absence of Corticosteroid-Binding Globulin in 10,000 Subjects

We developed a simple precipitin test that allows detection of human corticosteroidbinding globulin (CBG) on Ouchterlony plates. Using this test, we screened 10,124 sera for CBG and found it to be present in each sample examined.
