Marketlab Clarity Hemoglobin Test delivers rapid, point-of-care hemoglobin and estimated hematocrit analysis for physician offices, clinics, urgent care centers, and mobile blood screening programs. Engineered around the CLIA-waived Clarity HbCheck platform, the handheld optical reflectance meter evaluates a single 10 µL drop of capillary or venous whole blood and produces quantitative results in under 15 seconds. Paired with dry-reagent test cartridges offering 90-day open-vial stability and automatic code-chip calibration, this compact system minimizes reagent waste while supporting high-volume testing with 1,000-result onboard memory and dual battery or AC power operation.
