Roche Chemstrip Urine Test Strips

Manufacturer Description:

Vitamin C can interfere with urinalysis results. At high concentrations in urine samples, vitamin C can produce false negative results - particularly with glucose or blood (hemoglobin).1
There's a simple solution to help prevent false-negative blood and glucose results. Chemstrip urine test strips - for visual analysis or for automated testing with the Urisys 1100 urine analyzer. Only Chemstrip urine test strips help reduce Vitamin C interference. That's because they're designed with an iodate-impregnated mesh layer that oxidizes ascorbic acid and virtually eliminates the possibility for vitamin C interference.2
