Follow up question: Do you have pH test strips that go lower than 5.5 for use with urine to test the body's acidity/alkaline?

The hydrion ion lo pH test strips can be used to detect pH in the range of 1.0 to 11 (item #894157) or 3.0 to 6.0 (item #894160).

I can't give you a specific answer. In my opinion it is a product that you can use regimentally or as you feel you need it. I don't use it regimentally. I am not too concerned about how long it lasts as much as how effective it is. If you think you need to use it according to the directions on the label perhaps you may want to buy pH strips to test the efficacy of the product. Although I am neither a dietician nor a health expert I have read that our diets contain an imbalance of acidic food products and that we should strive for a balance between acid and alkaline. There is literature out there that will give you the guidance you seek. Good luck and good health to you.///

Other customers have said yes to that, however I wouldn't waste anymore of my money on these Test Strips. They are worthless and totally unreliable; I took 5 strips out, drew blood and took 5 consecutive readings. The readings went from 106 to 220..........so with that kind of inconsistency, they are not dependable.

The test strip you are using is not accurate/sterile enough to accurately test the PH of water...One thing that everyone should know about these (and other) pH test strips is that they work based on the TDS (total dissolved solids) that are present in the water you are testing. If you are trying to test a true distilled water (with nothing in it, no TDS) the strips won't be effective and I'd recommend you use a test drop for the water sample.

The outer or end pad tests the ph by testing the concentration of hydrogen ions present, hydrogen ions have a positive charge (H+) and are acidic. The other pad I believe tests the presence of hydroxl ions, they are negative (OH-) and are alkaline. It seems the strips are testing the positive (outer pad) and the negative (inner pad) to get a more accurate results. One pad (outer) tests the H+ while the other tests the OH-. The more H+ the lower the ph and the more OH- the higher the ph. So each pad approaches the test from opposite ends of the scale making them complimentary. One pad sensative to the + ions present and the other sensative to the - ions. The outer pad should be sufficient and the inner one just as a back-up. To really simplify, the outer pad begins at 0 through 14 (0-1-2-3-4-5-6-7-8-9-10-11-12-13-14) and the inner pad begins at 14 through 0 (14-13-12-11-10-9-8-7-6-5-4-3-2-1-0). In the ideal, the outer pad (H+) and the inner pad (OH-) should reflect the corrosponding colors to a certain ph but in the real world they may be off a little. When (H+) and the (OH-) are balanced the ph is 7. The reason we are told to use the outer pad is because testing ph by measuring the hydrogen ions is the most common method but either pad should give the same result.

Hi Mike, pH Dips have been designed to indicate whole number values for pH and you should easily be able to estimate 0.5 or half units as colors on the test strip may fall in between two whole numbers. I hope this helps. Thank you for your purchase.

I don't see why not, but you will have a higher risk of contamination. The best results can be obtained by using a dropper or dipping into the fluid. Then blotting the excess by tapping the strip sideways on an sheet of paper. Saliva pH can vary greatly depending on what you eat. Make sure you wash your mouth and wait 30-60 min before taking a sample.

I feel weird actually being able to help with this question but I happen to work as a prenatal chemical analyst as well as buying these indicators. This product has been successfully used as a component of laboratory testing, to determine whether a given fluid sample is urine or amniotic fluid, via pH (obviously). So basically, I think they'd work on most reasonably clear bodily fluids. I would strongly suggest collecting a fluid sample for testing, rather than employing this product in vivo (don't stick the strip directly into any part of your body). I'm not a doctor, this is advice provided for education/entertainment only, all the above is based solely on my personal experience, etc.

You mean after you test and it's pos. Or negative can you then send stick to be analyzed. Probably not enough urine absorbed to retest same urine or anyway to verify it was you who took the test to show someone that look I was or is positive or negative .. But in 98% of the tests were good.. A couple out of a 100 I have used something about urine above the line or mishap didn't register correctly tests are good..

FROM HM DIGITAL: The PH-200 is an ideal, waterproof pH meter for testing applications such as hydroponics & gardening, pools & spas, aquariums & reef tanks, water ionizers, drinking water as well as other liquids. It should NOT be used for testing distilled water or acids, as they may damage the sensor. It also should NOT be used to test solids, including soil. For more information, please visit www.tdsmeter.com/products/ph200.html

it's still positive, maybe not enough urine was used...you can use another strip just to be sure, but it has been my experience that a faint 2nd line means positive

i have only used them for testing drinking water and they do not work. the ph level does not change colors. you should go to a home depot type store and get a soil testing kit from their garden department. i should have returned this product but since i forgot too now it's wasted money.

The other answers are correct, normal biological pH is (neutral) 7; moreover, it is a specific range from 7.35 - 7.45. The human body employs bicarbonate to buffer the blood pH and maintain this narrow range. Saliva and Urine may vary more significantly. Urine is typically more acidic in the morning from pH of 6.5 - 7.0 and gradually more alkaline through the day to normal range of pH 7.5 - 8.0 in the evening. Saliva (human) has a normal pH range from 6.5 - 7.5.

The bottle says that the color code is light bluish for 8.5 and higer, so you probably wont be able to accuratly tell what the ph is if it higher. If your just testing regular things like your gardens water you will almost never get any reading that are higher than 8 or lower than 4 (or atleast i would hope so). Hope it helps a little!

Donna, no, I do NOT believe that these strips would work. According to the US Food and Drug Administration, the pH of orange juice ranges from 3.3 to 4.2, and these strips do not measure below 5.5. However, there are sellers on Amazon who sell "full-range" pH tape (range 0 - 13) and also I just noticed a tape ( http://www.amazon.com/gp/offer-listing/B005OD7AEM/ref=sr_1_9_olp?ie=UTF8&qid;=1414598453&sr;=8-9&keywords;=ph+paper&condition;=new ) that measures from 0 to 6, which looks like it would be PERFECT for orange juice.

My strip were colored also. They do work. It is like the red ph liquid tester that only changes color when ph lower than 7.8 is present.

I don't think so, the PH range on these strips is 6.2 to 8.4. These strips are very good but not for the PH range you're looking for.
