Key ComponentsThe Meter: A digital display unit with a microprocessor that reads electrical signals and shows blood sugar levels.Test Strips: Single-use disposable strips coated with special enzymes (like glucose oxidase) that react with a blood sample.Lancing Device: A spring-loaded tool holding a small needle to prick the skin.Lancets: Tiny sterile needles used inside the lancing device to get a small drop of blood.How It WorksA small drop of capillary blood—usually from the side of a fingertip—is placed onto the test strip.The enzyme on the strip reacts with the glucose, creating a tiny electrical current.The meter measures this current and displays the sugar level in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L) within five to ten seconds.
