After using Trident since the beginning, do you all notice that the CA Reagent only stay STABLE and last about 6 weeks? Usually, when I have about 20 tests left, the CA # start drifting up to the point it gave error on CA out of range. 450, ----> over 850. It seems like opening a new bottle gets everything back to normal. so the 2 months kit running 4 times test a day will only last a month and a half.
