One morning, his cousin Maria called. "I feel dizzy and thirsty all the time. Can I borrow your meter? I think I might have diabetes."
Larry almost said yes. But then he remembered what his doctor told him: This device is not for diagnosis.
So instead, he said, "Let's go to the clinic. My meter is great for checking how my treatment is working, but it can't tell you if you have diabetes."
Maria went. Turned out her symptoms came from dehydration, not diabetes. A good thing Larry knew the limit of that little device.
What a glucose monitoring system does
Uses a tiny drop of fresh capillary (fingerstick) or venous whole blood
Measures glucose quantitatively
Designed for external use only
A helper tool to see how well diabetes management is working
What it does NOT do
❌ Diagnose diabetes
❌ Test newborns
And one golden rule: accuracy matters. Store strips properly, check expiration dates, and if a result feels off, double‑check.
Because whether you're like Larry or just helping a friend, knowing what your meter can and can't do makes all the difference.

- A reliable friend, but not a doctor.
