The best glucose meter isn't a brand. Medicare covers 300 test strips every three months for insulin users, and 100 for everyone else.

CGM vs finger stick gaps are usually two compliant devices, not one broken one — sensors read interstitial fluid, which trails blood by minutes.

Every OTC CGM caps what it displays. Lingo reports only 55–200 mg/dL — outside that, the app shows no number at all.

Glucose and A1C measure the same sugar on different clocks: one captures this morning, the other 3 months, with the last 30 days weighing heaviest.

Types of glucose tests differ more than patients expect. An A1C of 6.8% can read
6.4-7.2% on a repeat of the same blood sample.

Glucose in urine points most people straight to diabetes. That kidney threshold, quoted as 180 mg/dL, is reported from 54 to 300 in diabetes.

The oral glucose tolerance test measures two hours of your body clearing a 75g sugar load — and roughly 20% of results come back non-diagnostic.

Fasting before a glucose test means at least 8 hours, water only. But two of the five common glucose tests require it — the other three don't.

High blood sugar without diabetes usually has a plain explanation — and one of the six is simply how your test was taken. Fruit residue alone can skew it.

Low blood sugar symptoms follow a sequence: adrenaline first, then the brain running short of fuel. That order is why confusion is the more serious sign.
