During a one-year period, six patients were admitted to the hospital in diabetic ketoacidosis following 12 to 24 hours of illness at home. Urine testing with strips impregnated with sodium nitroprusside had indicated that no ketone bodies were present. Nine of 11 bottles of reagent strips in use for less than three months by these and other patients contained totally unreactive strips. Nitroprusside tablets exposed more than three months continued to give accurate readings.
在一年时间里，有6名患者在家中发病12至24小时后因糖尿病酮症酸中毒入院。用浸渍有硝普钠的试纸进行尿液检测显示不存在酮体。这些患者及其他患者使用的11瓶试剂条中有9瓶使用时间不到三个月，其中的试纸完全无反应。暴露超过三个月的硝普钠片剂仍能给出准确读数。
