Q: How many tests can be done with one kit?
A:  Each kit (jar) contains 4 vials that can be used to perform 4 tests.
      Each Box contains 25 kits of 4 vials that can be used to perform 100 tests.

Q: What does it mean if the vial remains yellow for the first 48 hours, but changes color a couple of days later?
A: The reagent in the test vial detects the presence of an enzyme produced by coliform bacteria.  However, the enzyme can sometimes be present at very low concentrations from other sources or from dead bacteria.  In some cases, this can result in colour change after the recommended 48 hour period (after 4-5 days or even longer).  However, if the vial did not change color within the first 48 hours it is a clear indicator that there is no viable (live) fecal coliform bacteria in your water.
