On Call Plus Glucose Strips 50s provides a vial of 50 disposable test strips engineered for reliable quantitative blood glucose monitoring, essential for people with diabetes to track levels and adjust treatments. Each strip features a chemical reagent that reacts with glucose in capillary whole blood, measured by the glucometer's optical reflectance for precise readings (accuracy surpassing industry standards). Compatible only with On Call Plus meters, they accommodate a hematocrit (HCT) range of 30-55% to minimize errors from varying blood composition, and need only a tiny 0.4μl sample obtained via finger prick for rapid 4-second results displayed in mg/dL or mmol/L. User-friendly with no coding required, simply insert the strip, apply blood to the designated area, and remove excess if needed—avoid air bubbles or contamination for accuracy. Suitable for self-testing at home or clinical use, but not for neonates or alternate site testing without validation. Store in a cool, dry place at 2-30°C, tightly sealed away from humidity, light, and children; use within 3 months of opening and check expiry (typically 18-24 months). Discard used strips properly to prevent infection; if results seem inconsistent, recalibrate the meter or consult a healthcare provider. Not for diagnosing diabetes—pair with lifestyle and medical advic
