This was posted on another list that I am on and thought that I would pass this along to ones here. It is about using Bayer Clinistix for testing and why this person will no long use them.
"I changed the testing strips that I used last
week, and I want to tell you all, DO NOT BUY THESE STRIPS. I got Bayer
Clinistix for urine glucose testing. The strips have a pink test patch, and
there are only 3 results you can get, pink (neutral or negative) light
purple (medium spillage) and dark purple (heavy spillage). The instructions
say to check the results at 10 seconds, and disregard any results after 10
seconds. When they say 10 seconds, they mean EXACTLY 10 seconds. The
instructions also say to swipe the test strip on the edge of your container
to remove any excess. Well, doing this will make your test more than 10
seconds, and will skew the results. I did the test 5 times in 2 days and
got 5 different results. If you use these, you have to dip the strip and
start the test EXACTLY at the same time to get an accurate reading, and if
you go longer than 10 seconds, even by one second, you will get inaccurate
results, because the strips will start changing at 10 seconds and will
continue to change until they read the maximum reading. DO NOT BUY OR USE
THESE STRIPS."
