How does the urinalysis reagent strip detect the presence of glucose?
The detection of glucose by test strips is based on the enzymatic reaction of glucose oxidase.
What is the reagent used in test for glucose for urinalysis?
When a hexokinase reagent strip is used, glucose concentrations below 2 mg/dl in morning urine from a fasting person correlate well with urinary tract infection. Large amounts of urinary glucose suggest diabetes mellitus, or, rarely, renal glycosuria.
What is the principle of the reagent strip for urine protein?
It is based on the Griess’ test principle. In an acidic medium, Nitrite in the urine reacts with p-arsanilic acid to form a diazonium compound. The diazonium compound in turn couples with 1 N-(1-naphthyl)- ethylenediamine to produce a pink color.
What do Reagent Strips for urinalysis test for?
Tanner Scientific® 10 Reagent Strips for Urinalysis provide tests for Glucose, Bilirubin, Ketone (acetoacetic acid), Specific Gravity, Blood, pH, Protein, Urobilinogen, Nitrite and Leukocytes in urine.
What reagents are used in the glucose test on the reagent strip?
Glucose is first oxidized to produce gluconic acid and hydrogen peroxide in the presence of glucose oxidase. The hydrogen peroxide reacts with potassium iodide chromogen in the presence of peroxidase. The extent to which the chromogen is oxidized determines the color which is produced, ranging from green to brown.
Will all sugars be detected by the reagent test strip for glucose Why?
Will all sugars be detected by the reagent test strip for glucose? Why? Only glucose will be detected, because the reagent strip uses glucose oxidase. Other sugars must be detected by a test for reducing substances (Benedict’s copper reduction method) which will pick up such sugars as fructose.
How do you use reagent strips?
Use a fresh, well-mixed, uncentrifuged urine. Hold the reagent strip by the opposite end from the test areas and dip the stick into the specimen so that all test areas are immersed in the specimen. Remove the stick immediately. Prolonged immersion in the sample may wash out the test reagents.
How do we perform quality control of urine reagent strips?
The following precautions should be observed when handling and storing urine reagent strips: Store strips according to the manufacturer’s recommendations. DO NOT expose strips to moisture, volatile fumes, or direct sunlight. Remove only enough strips for immediate use and immediately recap the bottle.
How does a strip test work?
The most common kits use a test strip or dipstick, which you hold in your urine stream as you urinate into the toilet. With other tests you may urinate into a cup and dip the test strip into the cup. A section of the strip changes color if hCG is detected, indicating that you are probably pregnant.
Which sugar S does the reagent strip detect?
Only glucose will be detected, because the reagent strip uses glucose oxidase. Other sugars must be detected by a test for reducing substances (Benedict’s copper reduction method) which will pick up such sugars as fructose.
How do you use urine strips?
Dip the strip into the sample for no longer than 2 seconds and remove any excess by wiping the test strip on the side of the container. 3. Read the results after 60 seconds (for testing for Leukocytes, read after 90-120 seconds).
What is ururinalysis reagent strips?
Urinalysis Reagent Strips are made for urinalysis of both qualitative and semi-quantitative, which are in vitro reagent for diagnostics. It tests Leukocytes, Nitrite, Urobilinogen, Protein, pH, Blood, Specific Gravity, Ascorbic Acid, Ketone, Bilirubin, Glucose, Microalbumin in urine.
What is urs-2p urine reagent?
Urinalysis Reagent Strip URS-2P are made for urinalysis of both qualitative and semi-quantitative, it is used for test Glucose and Protein in urine specimen. 2 parameters result in one strip.
What is Urs 4SG test strip used for?
Urine Strip URS-4SG. Urine Test Strips URS-4SG are made for urinalysis of both qualitative and semi-quantitative, which are in vitro reagent for diagnostics. It tests Glucose, pH, Specific Gravity and Protein in urine.
How do reagent strips work?
Reagent strips are plastic strips with pads containing chemicals. The urine reacts with the chemicals to produce a color in the pad and the color correlates with a specific value for each pad. Pads are on the plastic strip for testing glucose, bilirubin, ketones, specific gravity, blood, pH, protein, urobilinogen, nitrite, and leukocytes.
