Anyway-- I understand the urinary pH very well now. I am still understanding saliva pH. Most practicioners actually don't use saliva pH as much as urinary pH, at least from my reading.
I would be interested to hear your breakdown on salivary vs. urinary pH.
For example-- could list out the imbalances if:
1. high (alkaline) urinary, low (acidic) salivary and vice versa
2. low urinary and low salivary
3. high urinary and high salivary
I am also interested to know if you think the salivary should be slightly acidic. The urinary should be between 6.4-6.8, and if it gets more alkaline one is prone to urinary tract infection (according to pathology books). With the urinary pH however, one can often think they are alkaline if they have a high pH (usually 7.8 and higher). With these people, they are actually tend to have so much acid that the body has to buffer them with ammonia. This is easy to test for with Nestlers reagent.
I am curious however, if it is a bad thing if saliva is too alkaline. I don't think that very high alkaline saliva represents emergency alkalosis-- probably just very a state of alkalosis. (respiratory or metabolic)
Also, there is quite an interesting test out there called the Bioterrain Analysis that compares all the different pH's and redox values of blood, saliva, and urine.
