Combur-Test® strips

The trusted choice in urinalysis for over 50 years

  • A dry chemistry test for the early and reliable detection of kidney diseases, diabetes and urinary tract infection (UTI)
  • Used for prevention screening, treatment monitoring and patient self-testing
  • Used as a trigger for further investigation - such as microscopic and bacteriological examination
  • Available as a visual or instrument test strip
  • Efficient analysis with a consistent reading time of 60 seconds for all parameters 
  • Applied nylon mesh ensures uniform penetration of the urine and uniform color development 
  • Separate diazonium salt mesh improves reagent stability and color differentiation in the leukocytes test
  • Virtually eliminates vitamin C interference on the glucose and blood pads

Combur-Test urine test strips from Roche have iodate impregnated mesh layers and are uninfluenced by ascorbic acid.

A quality choice for professional use

The Combur-Test® strip offers benefits in a number of areas:

Accuracy

  • Detects even low concentrations of glucose and erythrocytes/hemoglobin (5 – 10 Ery/mL) in the presence of vitamin C

Efficiency

  • Eliminates retesting and false-negative results in glucose and blood even under high levels of ascorbic acid (up to 400 mg/L) with the application of an iodate-impregnated mesh layer

Safety

  • Unique sealing technology means no interference from glued components 
  • Absorbent paper stops test area colors running 
  • Color compensation pad reduces risk of false results from strong intrinsic urine coloration*
  • Safe and hygienic strip handling - strips face downwards so your fingers stay clear of the specimen

* Only for instrument tests

Ascorbic acid - Vitamin C
Ascorbic acid and its interference with urinalysis results of urine test strips
Summary: Urine reagent strips are a useful tool for investigating, diagnosing and screening diseases immediately. Reliable and precise results are important, since adulterated results can lead to false negative results or re-testing of patients.

The influence of ascorbic acid on urine test strip pads for hemoglobin and glucose can be largely excluded using iodate impregnated mesh layers such as applied in the Combur-Test.
