Direct correlation was found between the results of a radioimmunoassay, electron microscopy and immunohistochemistry in cases of STH-secreting and hormonally inactive hypophyseal adenomas. In hyperprolactinemia and a simultaneous increase in the levels of 2 or more hormones the results of the radioimmunoassay coincided with those of electron microscopy and immunohistochemistry in 50-70% of the cases.
