Effect of handling of plasma samples on histamine radio-enzyme assay

Int J Biochem. 1989;21(6):675-8. doi: 10.1016/0020-711x(89)90389-3.

Abstract

1. Freeze-thawing of plasma samples increased the histamine level at physiological histamine concentrations as analyzed by radio-enzyme assay, but not by high performance liquid chromatography. 2. Heating of plasma samples decreased the histamine levels. 3. Enzymatic or non-enzymatic formation of histamine during handling of plasma samples was not detected. 4. Some albumin preparations contain histamine.
