Amanitin

Intoxication with Amanitin has been reported to be lethal in up to 25% of all cases and the mortality rate in children under 10 years of age is above 50%. Therefore, this intoxication should be ruled out in all patients presenting gastrointestinal symptoms after a mushroom ingestion. Amanitin analysis in urine is a valuable diagnostic tool and does significantly contribute to the management of mushroom poisoning.


Melatonin

Melatonin, the major hormone secreted by the pineal gland, is a key modulator of seasonal and circadian biorhythms. The synthesis and secretion of melatonin is controlled by a circadian clock in the hypothalamus and is synchronized by the light-dark cycle. BÜHLMANN provides the gold standard in immunological determination of melatonin with different RIA and ELISA.
