Hello! I could use some advice. For various reasons, I feel the need to check a fasting, random and post-prandial glucose level on several family members. I cannot afford to purchase several monitors to do this only once for each person involved. None have any contagious illnesses. Is there a safe way to use one monitor for checking 4 people (one set of 3 checks each) this once? Our granddaughter is working on a science project that needs this data. It will be a great learning opportunity for her and her class. Thanks to any and all who respond.
