Divide by 1.12 to go from plasma to whole blood readings.

For personal meters purchased within approximately the past three years, this correction factor from whole blood to plasma is already built in. The meter makes the correction automatically as part of its programming.
However, if you have an older meter (like my Glucometer Elite from 1997), then the meter's value should be multiplied by 1.12. |
