If using a tuberculin syringe instead of insulin syringe-how much should i draw up?

If using a tuberculin syringe instead of an insulin syringe, you should draw up 0.1 mL of the medication. This is because tuberculin syringes are calibrated in tenths of a milliliter, while insulin syringes are calibrated in units. Each unit of insulin is equal to 0.01 mL, so 0.1 mL of medication would be equal to 10 units of insulin.
