Traditional Blood Glucose Meters (BGM)

Also known a s fingerstick meters, thee remaid the most widely adopte devices globally due te their ir low cost, reliability, and established track discentrard. They require a small drop of capillary blood, usually from a fingertip, placed on a disposable tect strip that is intted the meter.

How They Work

Te teste strip contains enzymy (typically glucose oxidase or glucose dehydrogenase) that react witch glucose in thee blood. The meter measures an electrical contract or colar change, converting it into a numerical glucose reading, often displayed with in five seconds. Calibration with a control solution is peridically rexded to ensure proximacy.

It i i ich also the practical choice for continlele witch type 2 diabetes who tett less frequently (np., once or twice daily) or those with out insurance coverage for continuous sensors.

Continuous Glucose Monitors (CGM)

CGM ma transformed diabetes care by provising a continuous straam of glucose values, typically every one to five minutes, alongwigh trend arrows andd alerts. They consist of a small, explicble sensor insertted just under the skin (usually ite abdomen, arm, or thigh) that merures glucose in the interstitial fluid - the fluid arounding the bogy 's cells.

How They Work

Te sensor wykorzystuje a glukoza-oksydazę enzymy te generate an electrical signal districal to glucose concentration. This signal is transmitted wirelessly (via Bluetooth or intruitary radio frequency) to a receiver, insulin pump, or smartphone app. Most sensors mutt be replaced every 7- 14 days, though some implantable versions lass up to 180 days.
