Roche Combur 3 Test E x 50

Precise, secure and easy

Urine test strips from Roche Diagnostics (marketed as Combur-Test, except of US and Canada where Combur-Test is distributed as Chemstrip Test) are the result of years of targeted research and development. Their unique design and the thought-out technology ensure a maximum of reliability and convenience. Evaluation of results is always clear and reliable due to the easy-to-read, vertical color scale on the vial label, which perfectly matches reaction colors on the test strip patches.

Unique Design

• The reagent paper and underlying absorbent paper are held in place on a stiff white carrier foil with a fine porous nylon mesh laminated to the foil itself
• Unique sealing technology prevents from interferences of glue components
• The mesh protects sensitive test areas against contact, contamination and abrasion
• The mesh enables rapid and uniform penetration of urine into the test area, ensuring uniform color development
• The absorbent paper prevents interference by absorbing excess urine and stops test area colors from running

Ascorbic Acid Protected

• Alplication of iodate impregnated components prevent interferences from ascorbic acid (up to 750 mg/L)
• Ascorbic acid protection avoids retesting and prevents false-negative results in glucose and blood even under high levels of ascorbic acid

Distinctive Sensitivity

• Identification of even slight pathological changes in the urine
• Improved reagent stability prevents false leukocyte results in the leukocyte test pad
• Detection of even low concentrations of erythrocytes/ hemoglobin (5-10 Ery/µL)

Technical Specifications - Parameter combinations

• Name: PRO, GLU, BL

Test construction

• Composition: Reagent paper and underlying absorbent paper are sealed with a thin porous nylon mesh and fixed to a carrier foil
• Nylon mesh features: Protection from strip contamination. Homogenous liquid distribution and uniform color development. Prevention from falsification of the color by glue
• Practical detection limit: Detection limit is made such that even slight pathological changes in the urine are made visible by a clear color change in the test area

Vial construction

• Composition: Protection of test strips from atmospheric humidity with drying agent filled cap
• Color Scale: Special colorfast printing colors on the vial label allow easy and reliable evaluation of the resultsy
