Why do you use fluoride tubes to collect blood samples for glucose estimation in the laboratory?

flouride inhibits an enzyme involved in glycolysis. In order to prevent glycolysis in the drawn blood, tubes containing flouride are used.

Why is the test tube with distilled water included in the laboratory activity?
the purpose of distilled water is so that chemicals in the water do not interfere with the experiment :)
What color tube do you collect a fbs in?
I'm 90% sure that a FBS(fasting glucose) is drawn into a SST(serum seperator tube) A.k.a. "tiger top".
Which has more potential energy glucose or glucose plus P?
glucose does
Why is glucose important to science?
because if we do not have glucose we cannot produce a glucose..
What type of compound is C2H12O6?
Glucose. A reducing sugar.
Why sodium fluoride needed by glucose?
Sodium fluoride can be used as a preservative for blood samples (for the glucose determination) avoiding glycolysis.
How do you distinguished between sucrose and glucose in the laboratory?
Hindi ko alam
What laboratory department should glucose tolerance test be sent?
Chemistry
What is the action of NaF on glucose level?
decreases blood glucose, as fluoride inhibits enolase enzyme in glycolysis, and there is an accumulation of phosphenolpyruvate and no pyruvate being produced, thus no energy.
Sodium fluoride is the anticoagulant of choice for?
It is commonly used for glucose and lactate tests. The fluoride is used to stop/slow down processes in the red bloodcells(also in the other cells, but the erythrocytes have the biggest influence in this matter). Processes like the citric acid cycle, which uses glucose to produce energy in the form of ATP. In this process lactate is formed along with ATP. In other words, the glucose concentration in the plasma will decrease, and the lactate concentration will increase. When the blood is being obtained it will take about 30 minutes for the fluoride to start working.
What is in a gray tube for glucose testing?
From the BD web siteWhat is the glycolytic inhibitor in the gray top tube?Sodium fluoride acts as the glycolytic inhibitor and prevents the cells in the blood from utilizing the glucose.
What does GTT stand for and what type of tube would you collect?
Glucose Tolerance Test....not sure what tube you would collect it with....maybe a yellow top....
What are the advantages of using the enzymatic method for the determination of blood glucose?
Simply put, the enzymatic method ( eg. glucose oxidase and hexokinase etc.) is the best method for blood glucose concentration because of its specificity. This yeilds maximum specificity for glucose estimation even in a comlpex mixture. Sherry-Ann Ramnarine-Phillips
Why you use o-toluidine for glucose estimation?
In the presence of heat and acetic acid, ortho-toluidine (also called o-toluidine) reacts rapidly with aldohexoses (mostly glucose) to form a green-colored complex that can be measured at 630 nm.
What is a GTT test when performing phlebotomy and what tube is used to collect?
Glucose Tolerance Test Grey Top Tube.
What color tube is drawn for glucose?
It could be either red top (to clot it) or Grey top (sodium fluoride or potassium oxalate added) which prevents RBC's from metabolising the glucose in the blood. There is also another one to separate the serum but I forgot the color. It might be "tiger top" or speckled.
What would cause the greatest drop in a substance's freezing point... A. Barium Chloride B. Glucose C. Lithium Fluoride?
I suppose that barium chloride cause the greatest drop of the freezing point.
