[Importance of urinary methylhistamine measurements during allergy provocation tests].
Methylhistamine, histamine's metabolite, was measured in urine by radio-immuno-assay in 79 provocation test. Six of them were positive with clinical symptoms. All of the six were associated with a significant increase of urinary methylhistamine (UMH). Therefore, there is a good correlation between positive provocation tests and increase of UMH level. In these cases, the severity of clinical symptoms is related to the increase of U.M.H.
