how to test

hi can any 1 help me , how do i tell if i am taking the right dose of my backing injection ( lantus ) thanks dean

Hey Dean123

Well - Ideally your BI is your baseline dose which should keep BS within range regardless if you do not take your AQ during meals to cover the glucose rise. You should be able to tell wether your BI or QA dose is effective / correct by a few measures. For example my novorapid QA peaks around 90 mins and generally continues to work for 4 - 5 hrs, so if after a meal I hypo during this time I generally think it may be due to the QA of taking too much. Or vice versa if my BS are too high after I may require more QA with my meals to cover. It could of course also be due to incorrect carb counting and QA matching. However if you find that your BS are continually low or high regardless of these factors then it may be due to your BI. One way you could test this is to fast or have a carb free lunch etc, so you are QA and carb free, this way you will know if your BI is of the correct dosage as it should still keep you within range. If BS are too high it may need reducing or too low then increasing. This is what has helped me find out anyway,

you want to miss a meal ideally, but if not, have a carb free meal, then test your BG every hour for the next 5 hours, this means that the only insulin in your system will be your Lantus, if its held steady (within 1-2mmol/l) then its working, if it goes up, more insulin is needed, goes down, less insulin is needed........

you should repeat the test for 3 days, at different times for a better picture, in order to make sure any adjustment is actually needed................and remember, Lantus takes a few days to start working after adjustment....

good luck.....
