PH testing is not the definitive measurement to good health it is just one indicator! Remember also its not so much striving to be alkaline but to be balanced! Alkaline/Acid balance! ! One can also be too alkaline and also there are different opinions as to what is the correct balance! Some beleive 6.5 is perfect ,some may beleive a range between 6.0 and 7.5 is better! 7.5 to 8.0 is pushing the envelope!
The idea is more to mineralize and supply oxygen to the body !
Also there are medication that can cause to high a pH !
If one is eating properly getting the needed minerals and oxygen the pH should fall into range! If one is not feeling well or eating well the Ph tests mean little!
One has to listen to the body ,no matter what test readings one gets!
You also need to test saliva and urine for a few days after fasting for a few hours to get an accurate reading ! The link below may help you understand pH testing a little better!
