Normally I use Combur test strips as "Health Mate" is but cheaper, I wanted to test this manufacturer. Unfortunately, the DUS not work 10 test strips, they show a completely wrong result. I am plagued by constant bladder and renal pelvis inflammation and check with test strips my urine in order to intervene in case of an emergency quickly. According to this strip is with me always everything in the "green zone", while Comburstreifen Leukos, protein and nitrite already seen (which was in any case korrert / is). For this reason I can not recommend, in this case, you pay for something inexpensive unfortunately twice DUS 10 test strips.
