hi Mark
Yes, welcome, and thanks for the tip.
Other possible reasons for the strips giving negative results (when they "should" be positive) are discussed in the article Ketosis and Ketone Test Strips, from Low Carb Tips on the orange menu bar at the top of every page.
I'd also like to remind folks of the importance of TIMING when reading the strips. Read the label, and follow the directions exactly. If it says to take the reading at 15 seconds, then that is when you take the reading. Not at 30 seconds, not at 2 minutes. The chemical in the little pad on the end of the stick will continue to darken after the peak ketone reading, but this is due to the decompostion of other non-ketone products in the urine. Some folks who think they're testing "dark" all the time are actually waiting for the strips to turn as dark as possible before taking the reading. Don't.
There is yet another reason for faulty readings ... some folks have found they get more accurate results if they collect the urine in a small container, and then dip the test strip to take the reading. It seems that holding the strip directly in the urine flow may cause the chemical reagent to be washed out of the little pad ...
Just a few more reasons to NOT get hung up on those strips....
