Clinitest was usually run as a reflex test on urine samples with a negative dipstick glucose result. A negative dipstick glucose assay and a positive reducing test suggest that some substance other than glucose is present in the urine. These sugars include galactose, lactose, and fructose.

.

Also, what is a Clinitest used for?

Clinitest (reagent tablet) is a semi-quantitative test used for the determination of total reducing substances in urine, which include glucose, galactose, lactose, and pentose.

Subsequently, question is, how should Clinitest tablets be stored? Clinitest tablets are stable for long periods when stored at room temperature in unopened bottle. (Miles Inc. does specify expiration date on each bottle). The tablets are very hygroscopic, and cautions should be taken to avoid exposure to moisture.

In respect to this, what is reducing sugar in urine?

Reducing Sugars. Although glucose is the sugar most commonly tested for in urine, normal human urine can contain small amounts of galactose, lactose, fructose, xylose, and other pentoses. Galactosuria, an abnormal amount of galactose in the urine, occurs in infants with a congenital metabolic defect.

What are reducing substances?

Notes. Sugars (e.g, glucose, galactose, fructose, maltose, lactose, and pentose) are characterized as reducing substances based on their ability to reduce cupric ions to cuprous ions.

How do Clinistix work?

CLINISTIX™ sticks contain the enzyme glucose oxidase dried onto the paper pad at the end of the stick. This oxidises only glucose (and no other sugar) to yield gluconic acid and hydrogen peroxide. Depending on the amount of sugar, an overall colour ranging from blue through green to brown is produced.

What does the R mean on Clinitest hCG?

The Clinitest hCG Pregnancy Test is a chromatographic immunoassay (CIA) for the rapid determination of hCG in urine. A pink-colored line at the reference region (R), the area between the control line region and the test line region has been adjusted to a level approximating 25 mIU/mL hCG.

What does Clinistix test for?

Clinistrip. Clinistrip, also known as CLINISTIX or the brand name Diastix, are specific clinical sticks for the detection of glucose. Clinistrip consists of a section that contains glucose oxidase that has been dried onto the paper pad. It is an example of a biosensor-based test for glucose.

What is Icotest?

Ictotest^® Reagent Tablets are used to test for the presence of bilirubin in urine. The presence of bilirubin is an important finding in the evaluation of liver function and a positive detection could be an indication of liver disease such as jaundice, cirrhosis or hepatitis.

What does Benedict's solution test for?

Benedict's Test is used to test for simple carbohydrates. The Benedict's test identifies reducing sugars (monosaccharide's and some disaccharides), which have free ketone or aldehyde functional groups. Benedict's solution can be used to test for the presence of glucose in urine.

Why is glucose a reducing sugar?

Glucose is called a reducing sugar because it can be oxidized by, and thus reduce, mild oxidizing agents such as Cu or Ag. Glucose is an aldose, which means that its open-chain form contains an aldehyde group. Aldehydes are quite easily oxidized to carboxylic acids. So a mild oxidizing agent will be reduced by glucose.

What are ketones in urine?

If your cells don't get enough glucose, your body burns fat for energy instead. This produces a substance called ketones, which can show up in your blood and urine. High ketone levels in urine may indicate diabetic ketoacidosis (DKA), a complication of diabetes that can lead to a coma or even death.

What are the reducing substances in urine?

Urine for reducing substance (URS) is a non-specific screening test used to detect substances that chemically react with cupric sulphate [6]. A positive result is seen with common reducing sugars like glucose and galactose [6].

Is sugar in urine dangerous?

Sugar in the urine, as a sign of high blood sugar, may be associated with potentially life-threatening complications. Because sugar in the urine can be caused by diabetes, failure to seek treatment can result in serious complications and permanent damage.

Is it bad to have sugar in your urine?

Once the blood sugar level gets higher than 180 mg/dl, the kidneys start to spill sugar into the urine. The higher the blood sugar, the more sugar comes out in the urine. If your kidneys are normal, this usually isn't a problem, but if you have diabetes, too much sugar can cause kidney damage.

How do you test for a reducing sugar?

In lab, we used Benedict's reagent to test for one particular reducing sugar: glucose. Benedict's reagent starts out aqua-blue. As it is heated in the presence of reducing sugars, it turns yellow to orange. The "hotter" the final color of the reagent, the higher the concentration of reducing sugar.

What test is used to detect sugar?

Health care professionals most often use the fasting plasma glucose (FPG) test or the A1C test to diagnose diabetes. In some cases, they may use a random plasma glucose (RPG) test.

What is the difference between reducing and non reducing sugar?

Reducing sugars are sugars where the anomeric carbon has an OH group attached that can reduce other compounds. All monosaccharides such as glucose are reducing sugars. A disaccharide can be a reducing sugar or a non-reducing sugar. Maltose and lactose are reducing sugars, while sucrose is a non-reducing sugar.

What causes reducing substances in stool?

Testing for fecal reducing substances (carbohydrates) aides in determining the underlying cause of diarrhea. Increased reducing substances in stool are consistent with, but not diagnostic of, primary or secondary disaccharidase deficiency (primarily lactase deficiency) or intestinal monosaccharide malabsorption.
