How to carry out a pH saliva test:

To ascertain whether phosphate sensitivity may be the underlying cause of your problem or your child's problem, it is possible to carry out a simple pH saliva test. The test involves measuring the acid or alkaline levels of your saliva with universal litmus paper. Litmus paper is available from pharmacies, laboratory suppliers or suppliers of swimming pool chemicals. Use litmus paper in the range of pH 6 to 9.

pH is measured on a scale from 0 (which is extremely acid) to 14 (which is extremely alkaline).

The test involves wetting a strip of litmus paper with your saliva, observing a colour change and recording the result.

A pH of 7 is neutral, neither acidic nor alkaline. The optimum pH level of a normal unaffected person is between 6.8 and 7.2, i.e. it is very slightly acidic or very slightly alkaline. The saliva of a person sensitive to the high intake of phosphate will be distinctly alkaline and pH readings in the range of 7.5 to 8.5 are common. If you or your child has alkaline saliva, the litmus paper will change colour and show the level of alkalinity.

IF
you or your child has been diagnosed with ADD/ADHD or you are concerned that you or your child may be affected by this syndrome ....

AND
the litmus paper test reveals that you or your child's saliva has a pH value above 7.5 ......

IT IS HIGHLY PROBABLE THAT YOU OR YOUR CHILD CAN BENEFIT FROM HAFER'S RECOMMENDATIONS.

BUT NOTE: THE pH TEST WILL NOT NECESSARILY WORK IF YOU OR YOUR CHILD IS TAKING MEDICATION TO MANAGE ADD/ADHD.

Medications commonly prescribed for ADD/ADHD - such as Ritalin or Dexamphetamine - have the effect of making the saliva acidic.

Hafer has observed that children who are taking medication for their condition over a long period of time are more likely to develop dental caries - their acidic saliva attacks the enamel coating of the teeth, causing tooth decay. This effect may be masked if the water supply is fluoridated because water fluoridation protects the teeth from decay.

More detailed information about the link between the high intake of phosphate and the increase in saliva alkalinity is in Hafer's book The Hidden Drug - Dietary Phosphate.
