Questions and answers

The Geratherm® infection control provides evidence of the parameters leukocytes, blood, nitrite and protein in the urine. The test strip can either be held directly in the urine stream or alternatively in a container filled with urine.

The effectiveness of the test strips for urine tests has been proven in laboratory tests and clinical tests. The same samples were tested for comparison with another product available on the market (Bayer Multistix 10 SG Reagent Strips for Urinalysis). The results can be found in the instructions for use.


The test procedure for the leukocytes, or white blood cells, consists of detecting the specific for these cells enzymes. These cells are present in inflammation caused by infection. The color of the reagent zone turns from pink to purple when there is an infection. An increased protein concentration (> 500 mg/dl), an increased Elevated glucose concentration (> 2 g/dl) or an increased antibiotic concentration can lead to incorrect results.

If there is blood in the urine, the corresponding reagent zone changes color from orange to green or dark blue. Blood in the urine is a sign of a serious problem. If the result is positive, contact your doctor. Tests done on women who are menstruating often show positive results.

One urinary tract infection caused by any of these bacteria will cause the reagent zone to turn pink. Fast, a diet free of vegetables or taking medications containing phenazopyridine can lead to failure produce results.

Proteins in the urine can lead to false positive results for the leukocyte (LEU) parameter. if If there is protein in the urine, the reagent zone changes from yellow to green or blue.
