WELLION CALLA LIGHT METER WHIT

Overview & Mechanism of Action

• The Wellion Calla Light Blood Glucose Meter (compact white handheld monitoring device designed for intuitive daily glycemic monitoring) utilizes advanced electrochemical biosensor technology:
• Amperometric Glucose Oxidase Reaction: Measures blood glucose levels quantitative via capillary whole blood samples. When a small blood drop ($0.6\ \mu\text{L}$) is applied to a Wellion Calla Test Strip, the glucose oxidase enzyme on the strip catalyzes glucose oxidation, generating a tiny electrical current proportional to the blood glucose concentration.
• Auto-Coding & No-Code Technology: Eliminates manual code entry errors between different test strip lots, ensuring clinical accuracy and simplifying testing workflows for patients.
• Ergonomic Design & Visual Clarity: Features a high-contrast, large-digit LCD display with backlighting for easy reading in low light. The casing includes non-slip side grips and a hygienic strip-ejection mechanism to prevent direct contact with used test strips.

Clinical Indications & Uses

• The Wellion Calla Light Blood Glucose Meter (White) is indicated for:
• Quantitative measurement of glucose in fresh capillary whole blood for individuals with Type 1, Type 2, or gestational diabetes
• Routine self-monitoring of blood glucose (SMBG) to evaluate treatment efficacy, dietary intake, and exercise adjustments
• Tracking glycemic trends over time using stored memory, meal markers (before/after meal), and multi-day average calculations

Usage Guidance & Safety Precautions

Administration:

• Wash hands thoroughly with warm water and soap, then dry completely. Insert a fresh Wellion Calla Test Strip into the meter slot; the device will power on automatically. Use a lancing device to obtain a tiny drop of capillary blood ($0.6\ \mu\text{L}$), touch the tip of the test strip to the blood sample until the reaction chamber fills, and view the result displayed within 6 seconds.

Device Settings & Memory:

• Capable of storing up to 500 test results with time and date stamps. Calculates 7, 14, 30, 60, and 90-day glucose averages.

Precautions & Warnings:

• For in vitro diagnostic self-testing only. Use exclusively with compatible Wellion Calla Blood Glucose Test Strips and Control Solutions. Do not use expired test strips or damaged meters. Not intended for the clinical diagnosis of or screening for diabetes, nor for neonatal testing. Store the meter between $5^\circ\text{C}$ and $45^\circ\text{C}$ in a clean, dry place away from extreme humidity and direct heat. Keep out of reach of children.
