A member asked:

Why is serum glucose more accurate than finger tip glucose, when monitoring readings? how much faith can i put with a home glucometer?

A doctor has provided 1 answer

Plasma: has a higher water content than whole blood, so there is more dissolved glucose in plasma compared with whole blood, and readings are 15 to 20 percent higher.
