Re: How to determine histamine levels ?

Hi MsLacy,

I'm still trying to find this out as well. But as the other person said (sorry, I can't remember your name now, duh, bad memory) apparently the niacin test works pretty well at least with some.

You need to use nicotinic acid in a 50mg dose. You will flush from just one 50mg dose if you have high histamine levels. If you have low histamine levels it will take you 150mg or more to flush.

Cheers,
