@MrWorfMen's Mom So Bear is due an increase of insulin. I have the conversion chart U-40/U-100. I have printed a copy to put on my fridge. Small problem though the chart doesn't correspond to the syringes I purchased. Apparently I have goofed again and bought the wrong syringes at WalMart. My latest buy of syringes have increments of 5. They are ReliOn Insulin Syringes, Capacity 3/10 ml. cc. dosage up to 30 units, Gauge 29, Length 12.7 mm. (1/2"). The numbers are increments of 5 and each line in between would be a unit. There is no half units. I either have an incorrect chart for these syringes or I have the wrong syringes. The only positive, if I messed up again is that I haven't opened any of the bags and should be able to exchange them. Do I have the wrong syringes or do I need a different conversion chart?
