N-Methylhistamine

Optimal result: 79 – 140 µg/g creatinine

N-methylhistamine excretion is elevated with a high protein diet, in gastrointestinal food allergies, in irritable bowel disease, in colitis, in histidinemia, in chronic urticaria, in angioedema, and with interstitial cystitis.

N-methylhistamine is low in depression, in lupus, in focal segmental glomerulosclerosis, and in idiopathic nephrotic syndrome. Additionally, N-methylhistamine levels can be low in individuals with an alteration in the histamine N-methyltransferase gene.

N-methylhistamine is a major metabolite of the neurotransmitter histamine.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
