Medi-Test MED129 Combi-5S Urine Analysis Test (b, p, k, g, ph) 100 Strips. Medi-Test MED129 Combi-5S | Urine Analysis Test g, p, ph, n, aa | 100 Strips. Test strips for rapid determination of blood, protein, ketone, glucose, pH-value in urine. Blood: The detection is based on the pseudoperoxidative activity of hemoglobin and myoglobin, which catalyze the oxidation of an indicator by an organic hydroperoxide producing a green colour. Protein: The test is based on the „protein error“ principle of indicators. The test zone is buffered to a constant pH value and changes colour from yellow to greenish blue in the presence of albumin. Other proteins are detected with less sensitivity. Ketones: The test is based on the principle of Legal’s test. Acetoacetic acid and acetone form a violet coloured complex with sodium nitroprusside in an alkaline medium. Glucose: The detection is based on the glucoseoxidase-peroxidase-chromogen reaction. Apart from glucose, no other compound in urine is known to give a positive reaction. pH: The test paper contains indicators which clearly change colour between pH 5 and pH 9 (from orange to green to turquoise).
