ketone strips, blood sugar strips, calibration strips.... Anyone ever wonder why there is not a strip that measures the "freshness" of insulin. A strip you cound stick in your meter with a drop of insulin on it. Could it be that the companies that make insulin had rather you toss a bottle you suspect and open a new one$$$$$$$$$? Any pharmacists in here that know it to be impossible to develop because of the characteristics of insulin? Just wondering. Oh yeah, if there were such a strip, would you buy it?
