Many medical conditions can be investigated and detected by using medical urine test strips, and they are a great help to ascertain your health status.
Our strips are available for home use, and test simultaneously for the presence of glucose, ketones, blood, protein, nitrite, pH, urobilinogen, bilirubin, leucocytes in urine as well as specific gravity.
Glucose
This test is based on a sequential enzyme reaction. First, glucose oxidase catalyzes the formation of gluconic acid and hydrogen peroxide from the oxidation of glucose. A second enzyme, peroxidase, catalyzes the reaction of hydrogen peroxide with potassium iodide chromogen to oxidize the chromogen to colors ranging from blue through greenish-brown, and brown to dark-brown.
Ketones
This test is based on the reaction of acetoacetic acid in the urine with nitroprusside. The resulting color ranges from tan when no reaction takes place, to purple for a positive reaction. Normal urine specimens ordinarily yield negative results with this reagent.
False positive results may occur with highly pigmented urine specimens or those containing large amounts of levodopa metabolites.
Blood
This test is based on the pseudoperoxidase activity of hemoglobin which catalyzes the reaction of 3,3'5,5'-tetramethylbenzidine and buffered organic peroxide, 2,5-dimethylhexane-2,5-dihydroperoxide. The resulting color ranges from, greenish-yellow through bluish-green to dark blue.
Protein
This test is based on the color change of the indicator tetrabromophenol blue. A positive reaction is indicated by a color change from yellow through green and then to greenish-blue.
Nitrite
This test is based on the reaction of p-arsanilic acid and nitrite in urine to form a diazonium compound. The diazonium compound in turn couples with N- (l-naphthyl) ethylenediamine in an acid medium and the resulting color is pink. Any degree of pink color is considered positive, however, pink spots or pink edges should not be interpreted as a positive result. Color development is not proportional to the number of bacteria present.
pH
This test is based on double indicators (methyl red and bromothymol blue), which give a broad range of colors covering the entire urinary pH range. Colors range from orange through greenish-yellow and green to blue.
This test indicates the pH values within the range of 5 to 9.
Urobilinogen
The test is based on a diazotisation reaction of 4- Methoxybenzene diazoniurn salt and urinary urobilinogen in a strong acid medium. The color changes from pink to brown-red.
This test can detect urobilinogen in concentrations as low as 0.1 mg/dl: It should be noted that most normal urines may give a slight pink reaction, and a high concentration of formalin may give a false negative result.
Bilirubin
This test is based on the coupling of bilirubin with 2.4-dichlorobenzene diazonium salt in a strong acid medium. The color changes from light tan to pinkish-purple. No bilirubin is detectable in normal urine by even the most sensitive methods.
Leucocytes
This test reveals the presence of granulocyte esterases. The esterases cleave a derivatized pyrazole amino acid ester to liberate derivatized hydroxy pyrazole.
Specific gravity
This test is based on the pka change of certain pretreated polyelectrolytes in relation to the ionic concentration. In the presence of an indicator, the color changes from deep blue in urine of low ionic concentration.
As you can see - the test strips will test the entire spectrum of what can be tested by using urine dipstick test strips.
Instead of just testing for ketones or glucose, you can now test the entire spectrum of your urine, by using our very affordable urine test strips.
