Why is your finger prick and your CGM showing different numbers?

Many CGM users ask the same question: why doesn’t my sensor match my finger prick? This Lingo Basics explainer answers it in just over a minute. A blood glucose meter reads a snapshot of the glucose in your blood, while a biosensor (CGM) streams the story from the fluid just under your skin.

Both are accurate — they’re just reading different chapters. I was the Creative Director on this piece for Lingo, Abbott’s over-the-counter CGM division.
