Upcoming iOS 8.2 update will add blood glucose monitoring and data point descriptions to Health

For what we know, Apple is bringing in a reworked blood glucose tracking engine, this time with an option to manually choose the measurement unit - mg/dL or mmol/L, and newly added descriptions that help users make better use of Health. For example, blood glucose is now explained with this bit of information - “Glucose–also called blood sugar–is the main sugar found in the blood and the main source of energy for your body.” In the screenshots, you can see the descriptions of other data points - they are a bit more thorough.
