[QUOTE="plutoniumcard, post: 1162598, member: 292266"] I agree with what has been said. The strips generally react to other "chemicals". The best tip is to wash finger to be samples with warm water, and dry well. I have noticed that certain liquid soaps increase the readings. I think you need to bear in mind: a. the sample size take is tiny (5 uL or less). So a small amount of "contaminant" can significantly raise the reading. Also...if you don't dry your hands, you will get a dilution effect i.e. a false low reading. b. This type of equipment is improving in their accuracy and reproducibility of the results. Still not as accurate as a lab-based equipment used in hospitals. c. I have repeated high or "odd" readings and found that a 9.5 reading can when repeated 30 seconds later give a more acceptable 7.2mMol/L. d. different makes of glucose monitors will vary (as indeed there will be some variation even between those from the same maker. There is also potential for variation between batches of strips. This is normal, and described in the instructions. If your intuition says question a reading...repeat it! Tony [/QUOTE]
