URS-11 ( Urobilinogen/ Blood/ Ketone/ Glucose/ Protein/ pH/ Bilirubin/ Nitrite/ SG/ Leukocytes/ Ascorbic Acid ) description:

Los Angeles-based Diagnostic Automation/Cortez Diagnostics, Inc. offers a Urine Reagent Strip (Urobilinogen-Blood-Ketone-Glucose-Protein-pH-Bilirubin-Nitrite-SG-Leukocytes-Ascorbic Acid) Rapid Test for the semi-quantitative and qualitative detection of Urobilinogen, Blood, Ketone, Glucose, Protein, pH, Bilirubin, Nitrite, Specific Gravity, Leukocytes, and Ascorbic Acid in urine.  The Urine Reagent Strip for Urinalysis is for in-vitro diagnostic use only.

The Urine Reagent Strip (Urobilinogen) Rapid Test is based on a modified Ehrlich reaction in which p-diethylaminobenzaldehyde reacts with urobilinogen in a strongly acid medium.  This test will detect urobilinogen in concentrations as low as 0.2 EU/dl in urine.

The Urine Reagent Strip (Blood) Rapid Test is based on the pseudoperoxidase action of hemoglobin and erythrocytes which catalyzes the reaction of 3,3', 5, 5' -tetramethyl-benzidine and buffered organic peroxide.   This test has a sensitivity to free hemoglobin of 0.015 mg/dl, or 5-10 intact red blood cells/uL urine.

The Urine Reagent Strip (Ketone) Rapid Test is based on the reaction of acetoacetic acid with sodium nitroprusside in a strongly basic medium.  The sensitivity of the test provides semi-quantitative results and reacts with acetoacetic acid in urine.  This test does not react with beta-hydroxybutyric acid or acetone.  The reagent area detects as little as 5-10 mg/dl acetoacetic acid in urine.

The Urine Reagent Strip (Glucose) Rapid Test is based on a double sequential enzyme reaction.    The test area is specific for glucose; no substance excreted in urine other than glucose is known to give a positive result.  Approximately 100 mg/dl glucose in urine is detectable.

The Urine Reagent Strip (Protein) Rapid Test is based on the protein error-of-indicator principle.   The test area is more sensitive to albumin than to globulin, hemoglobin, Bence-Jones proteins, and mucoprotein; a negative result does not rule out the presence of these other proteins.  The test area is sensitive to 15 mg/dl albumin. 

The Urine Reagent Strip (pH) Rapid Test is based on the well known double pH indicator method, where bromothymol blue and methyl red give distinguishable colors over the pH range of 5-9.  The test area permits quantitative differentiation of pH values to one unit within the range of 5-9.  pH reading is not affected by variation in the urinary buffer concentration.

The Urine Reagent Strip (Bilirubin) Rapid Test is based on the coupling of bilirubin with a diazotized dichloroaniline in a strongly acid medium.  The test has a sensitivity of 0.4-0.8 mg/dl in bilirubin in urine.

The Urine Reagent Strip (Nitrite) Rapid Test depends on the conversion of nitrate to nitrite by the action of Gram-negative bacteria in the urine.  This test has a sensitivity to sodium nitrite of 0.0075 mg/dl. 

The Urine Reagent Strip (Specific Gravity) Rapid Test is based on the apparent pKa change of certain pretreated polyelectrolytes in relation to the ionic concentration. The test permits determination of urine specific gravity between 1.000 and 1.030.  The test correlates within 0.005 with values obtained with the reflective index method.

The Urine Reagent Strip (Leukocytes) Rapid Test is based on the action of esterase present in leukocytes, which catalyzes the hydrolysis of an indoxyl ester derivative.  The test can detect as low as 10-15 WBC/uL. 

The Urine Reagent Strip (Ascorbic Acid) Rapid Test is based on the action of a complex chelating agent with a polyvalent metal ion in its higher state and an indicator dye that can react with the metal ion in its lower state to produce a color change from blue-green to yellow.  The test can detect ascorbic acid in concentrations as low as 10 mg/dl in urine.
