It says to wait till the color changes from blue/green to orange red or pink. I get a more purple color first...then an orange/red if I add more drops. When should I stop? At the FIRST change of color or when it gets to the orange/red? I have not used this brand for ALK before and my reading seems to be out of wack,even with the supplied "calibration fluid" I use their Cal test kit so I am familiar with the procedure.
