Not sure what kind of test it is but they inject the water into a little plastic disk and put it into a machine that comes up with the results. This weekend when I go there I will see what the label in the machine says.

I have a real difficult time distingushing between the different shades of colors in most tests.
I have asked other people to look at the same test and most of the time im one ot 2 shades appart, so for a real test It is difficult for me.

for the quick strips I have to go as far as taking a picture of the test and then going to the computer to compare what the camera sees which makes the process quite anoying.
