THE IMMUNOLOGICAL ASSAY OF GROWTH HORMONE IN HUMAN SERUM

Abstract

SUMMARY: An immunological method for the assay of growth hormone in human serum is described. The method, based on that of Read, has a reproducibility of 20%; the normal mean level for adults was found to be 172 μg./l., and the range of two standard deviations was 88–256 μg./l. serum. The assay has shown raised levels in seven out of ten acromegalic patients and lowered ones in four out of seven hypopituitary patients.
