How much blood does one need to measure blood sugar at home?

The size of blood sample needed varies slightly depending on the model (from 0.3-10 ul). The newer models require considerable less blood. The smaller volumes of blood mean that you have to prick your self less often and this is also less painful.

The latest glucose machines can also measure glucose in other fluid as well. However, the technology of these continuous glucose meters is still evolving and not recommended for home use. The majority of consumers can get their glucose devices at little or no cost because of the rebates. The long term expenses are from the purchase of strips and other supplies.
