These strips are for use in determining a woman's vaginal pH balance & indicate the presence of yeast infections. Normal vaginal pH is in the 3.8-4.5 range, so above or below this can indicate a problem. If you get such readings, consult a physician before self treating.

As expected - and quick shipment.
Great strips. Very easy to use and a great value. Fast shipping!
Needed an easy way to check my materials for canning, especially my tomato sauces. These test strips saved me a lot of trouble since I didn't have to add any special acid to them after I discovered that mine were perfect at pH4.0. THis very simple test saved me a lot of money and i'm very happy with the product
