OneTouch Ultra Blue Test Strips incorporate DoubleSure Technology, which automatically verifies each blood sample twice to eliminate false readings and ensure diagnostic confidence. The FastDraw design requires only a microscopic 1 microliter blood sample that the strip automatically captures, minimizing testing discomfort while maintaining clinical accuracy. Results appear on your meter in just 5 seconds, enabling quick decision-making for diabetes management. These strips offer broad compatibility across the entire OneTouch Ultra family of meters, including Ultra 2, UltraMini, UltraSmart, and UltraLink models, providing flexibility for various testing devices. This 25-count vial delivers reliable glucose monitoring for approximately three weeks of daily testing. Each strip is single-use only and should be discarded after the expiration date to maintain accuracy and safety.
