thanks for asking
normally there is no diurnal variation of histamine level. its level increases at the time of anaphylaxis. whereas patients with unexplained anaphylaxis have plasma histamine levels within the normal range during asymptomatic periods; that plasma histamine levels in patients with mastocytosis exhibit a diurnal variation,with the highest values observed in the early morning (approximately 2:00 A.M.) and the lowest values in the afternoon (approximately 2:00 P.M.).
