混合胰島素的原則是「清澈到混濁（Clear to Cloudy）」。為了避免 NPH（渾濁）污染 Regular（清澈），必須先在 NPH 瓶中注入空氣，再到 Regular 瓶中注入空氣並抽取藥液，最後再回頭抽取 NPH。
The principle for mixing insulins is 'clear to cloudy.' To avoid contaminating regular (clear) insulin with NPH (cloudy), the nurse must first inject air into the NPH vial, then inject air into the regular vial and withdraw the regular insulin, and finally return to withdraw NPH.
