How Accurate Is pH Testing?

“My husband and I recently adopted the mostly raw Hallelujah Diet due to my husband’s recent diagnosis of prostate cancer. We adopted the diet rather than submitting to the surgery and radiation therapy route the doctor prescribed. After being on the diet a short time we both did a litmus test to check on whether our bodies were too acidic or not. My test showed I was fairly normal but my husband’s revealed that he was highly alkaline. Is this bad?”

Random testing of urine or saliva really tells us very little; these tests are not a very good guide as to the acidity or alkalinity of the body fluids.

The body will automatically maintain a stable blood pH of 7.35 to 7.40 as this is critical to sustaining life. Other body fluids have different pH levels.

Ideally, the first morning urine pH will be 5.8 to 6.2; that is if the liver is detoxifying the toxins throughout the night. The pH testing values will vary if one has to get up during the night to urinate.

Saliva pH also varies but is often slightly acidic (under a pH of 7.0). When checked about 15 to 30 minutes after eating or drinking, it should move into the alkaline range.

Because there are so many variables, we discourage people putting too much stock in pH testing of their saliva and urine.

I never check my pH. The Hallelujah Diet, after one has been on it for a period of time, should automatically keep the pH levels of the blood, urine, and saliva just right.

Eat right, exercise right, and pH will be right almost 100% of the time!


  1. Hello George, my question is how long will my PH be acidic after the chemo treatment got AML Leukemia A full blast of straight 7 days double doses of chemo plus two months of anti-biotics fungal infection in my lungs ..Now they say I have a viral infection which is making me deadly sick with body quivers or shakes but no fevers…something is wrong with this picture… my PH very acidic from your experience possible or is it something else that I have to ride it out like they said ?????
