Roche Combur 7 Test x 100
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: pH, LEU, NIT, PRO, GLU, KET, 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
