Although many of the blood glucose meter manufacturers do a case for the meter, finger pricker and bg strips to fit into, these type of cases are not that easy to use unless the case is put flat on a table or a seat and they are a bit on the big side to carry about in a bag. Ideally, the strips could be produced in foil which would enable the case to be more compact and lighter and finger prickers could be a tiny bit smaller and less noisy when the click sounds.
I think lots of diabetics would love a bg meter that could slide into a mobile phone type wallet with elastic sides and a clear front so that the meter buttons could be pressed without taking the meter out of the wallet and the finger pricker could be directly next to the meter and not really visable. Test strips in a very small container at the top. This would enable diabetics do be able to do a bg test wherever they might be...... on a train, bus, walking around the shops.
