I'm 43 and have had Type 1 since I was 6 years old. I have developed some serious callouses on my fingers and am having trouble getting a sample, let alone a big enough sample. I am actually having to do it manually, which is no fun. :(
Does anyone know of a solution to this? I have tried using a pumice stone on the callouses to no avail. Maybe a special deep penetration lancing device or lancets?
