Why do we carry a small water spray bottle in our diabetes kit bags?
Roo and TJ need to have their blood sugar levels tested using a finger prick blood test. Traces of anything, including print from a book can give false readings for the blood tests. So prior to any blood test they have to wash their hands using water without soap. Yes, that's right no soap. Even soap affects the test results. Lotions etc on wet-wipes and also the chemicals in the waterless hand washing gels will also affect the test result.
So if there is no sink available, we spray a finger with tap water stored in their spray bottles and then dry it with a cotton wool pad (there are some of those in the kit bags too).
