How to use pH Litmus Paper for Testing Urine & Saliva
- Tear off about 50mm (2 inches) of litmus paper and dip the litmus paper into the test solution.
- Instantly compare the resulting colour with the matching pH colour chart.
Testing your urine:
- Collect a fresh urine sample in a clean, dry container. First morning urine is often recommended.
- Or midstream*, quickly wet the pH plastic strip with your urine flow.
- Dip the litmus paper into the urine sample for 1 second, or midstream making sure the pad is fully wet.
- Immediately compare the colour of the plastic strip to the pH colour chart.
- Record your pH result and time of day for your own tracking or to share with a health professional.
Ideally, the pH of urine upon waking should be around 6.0 – 6.8 and move towards an alkaline state pH7 and above after eating.
* Midstream means to start your urination and when you feel you’re half finished, that’s when you dip your paper into the urine flow or when you collect a small sample for measuring.
Testing your saliva:
- Do not eat, drink or smoke for at least 15–30 minutes before testing.
- First swallow whatever saliva is in your mouth.
- Draw-up fresh saliva and then swallow.
- Repeat.
- Remove one strip from the vial and close the cap straight away.
- When you draw up saliva for the third time, spit this saliva onto a spoon, spit a small amount of saliva into a clean spoon or cup.
- Dip the litmus paper into the saliva sample for 1 second.
- Immediately compare the colour of the plastic strip to the pH colour chart.
- Record your pH result and time of day for your own tracking or to share with a health professional.
The same process applies if measuring throughout the day.
The pH of saliva upon waking should be around 6.4 – 6.8 and move towards an alkaline state pH7 and above after eating.

Frequently Asked Questions
Approximately how many tests per roll is there?
There is approximately 100 tests per roll depending on the length of paper you tear off each time.
For instance, if you used a strip of paper at 25mm or 1 inch, you’ll get close to 180 tests!
Can I use my pH Litmus Test Paper to measure the pH of water?
No. The reagent used in the pH Litmus Paper is designed for buffered solutions only.
What is a buffered solution?
A buffered solution is a solution with adequate dissolved solids to resist pH changes.
For example, urine and saliva are considered buffered in their natural state. However, rain water, tap water etc. are considered to be dilute, weakly buffered solutions.
For testing weakly buffered solutions, we recommend our water pH testing kits.
What do the results indicate?
- If you have high pH levels – you have low acid levels.
- If you have low pH levels – you have high acid levels.
This reading in turn can be used to adjust your diet and mineral intake so as to bring cellular terrain back into balance.

Thank you
I tried many chemists and health food stores to get these. Why are these so difficult to get? Thank you for your prompt delivery and information. Most helpful. I’ve recommended you to all my friends and I accept no responsibility for that.

No leach
I read on some websites that litmus paper leached making the readings wrong. These didn’t leach though the paper is a bit fiddly when wet. I’m on the pension so finding these has helped me a lot. Thank you
