Hi there, for a true ph reading this has to be done through an arteria blood test taken from an arteri in the wrist witch is a bit painful as i just had one done a couple of weeks back, other than that you can get some pretty acurate ph test strips witch come in various forms but can give you a fair reading. Currently using them myself as i'm boosting my ph as i have cancer,roughly following "vernon johnston's" protocol. bicarbonate of soda.check it out.
