Blood Glucose Strips

blackl b asked:


Well currently im giving my dog 17 units and i jsut checked her pee for glucose and the strip turned a brown color which comes out too 1 g/dL or 56mmol/L.

Also my dog is in heat. Would this effect the results? She’s been bleed for a while

Avoiding Glucose Monitoring Errors in Patients Receiving Other Sugars (February 2006)

This story originally aired in February 2006. In this Special Edition of PSN, we are repeating some of the most important safety issues that continue to pose a public health problem.

FDA issued a reminder about the potential for falsely elevated glucose readings in patients who are also receiving products that contain other sugars. These products include oral xylose, parenterals that contain maltose or galactose, and peritoneal dialysis solutions that contain icodextrin.

Several patients have died because of this problem. Their glucose readings were very high, so they were given aggressive insulin treatment. The glucose readings were falsely high, however, and too much insulin was administered. The patients suffered hypoglycemic shock or irreversible brain damage and died.

In these cases, the glucose meter was reading the patient’s actual blood glucose level, plus the maltose that was contained in the IV immune globulin he was receiving. The readings were falsely elevated because the glucose monitoring device couldn’t distinguish between glucose and other sugars.

All glucose meters don’t suffer from this problem. There are several kinds of enzymatic glucose monitoring methods that are used, and only one of those has this problem. This problem occurs only with the monitoring method that uses an enzyme called GDH-PQQ. This method is employed in some glucose monitoring devices used by diabetics at home and in point-of-care settings.

The other methods currently used in glucose monitoring systems are called GDH-NAD, GDH-FAD, glucose oxidase, and glucose hexokinase, and they are capable of distinguishing between glucose and other sugars.

The test method used in glucose meters is identified in the package insert that comes with the glucose test strips. The package insert is also available from the manufacturer. The most important thing to remember is not to use the GDH-PQQ method if the patient recently received other sugars. That includes oral xylose for a D-Xylose absorption test, or an IV solution containing maltose or galactose, or a peritoneal dialysis solution containing icodextrin.

ok so my hypothesis is that glucose has a faster rate of diffusion then starch, beccuz starch is a larger molecule. and now im trying to design an experiment around this….and im using dialysis tubing… anyways how can i meausre the concentration of my starch… we have urine strips to measure the glucose…. and also how much percentage would be best (of glucose and starch) would be best to use??? and how do u make these solutions???
i know how to dectect the presence i need to knoe concentrations!!!!

Ok this is my first post on here…

I have always gotten the shakes or a little lightheaded near meal time ( but was able to push it off without too much of a problem) for about 2 years now.

BUT THEN THIS WEEK IT HAS BEEN HELL. I started getting anxiety attacks and twitching, confused, and felt like I was going to have a seizure or pass out only an hour or 2 after a meal, so I would eat again to subside it… this just gave me indigestion and I never feel hungry because I am constantly trying to raise my sugar levels.

Anyway after about a week of this crap I decided to buy a glucose meter (the onetouch one) and strips and such… I coded them and tested solution and what not and I am getting readings like 75 to 84 just 2 hours after a meal. (his is were I begin to get the jitters).. I get readings like 130-145 within 45 minutes of eating.

Plus I cannot sleep, I wake up every 3 hours with confusion and tingling in my arms and legs. But I usually only test at 65-80.

Also, I usually eat quite a bit. I have meals of a footlong sub, chips and drink for lunch and usually one or sandwiches for dinner… I stuff myself.

Does this sound like hypoglycemia? I am getting really scared because I cannot seem to get it to go away.

Side note to my novel: I have also been suffering from painful congestion in my inner ear which is throwing my balance and stomach all out of whack.

heres the procedure
Procedure:

1. Put on your goggles.
2.Cut two strips of dialysis tubing (about 15 cm long) and soak them in a beaker of tap water for approximately 2 min.
3. Rub the dialysis tubing between your fingers to find the opening.(This is similar to the way you would open a plastic bag.)Tie know near one of the ends of the dialysis tubing. Repeat with the other piece of tubing.
4. Using a graduated cylinder, measure 15 ml of the 4% starch suspension. Pour the suspension into the open end of the dialysis tubes through the funnel.
5.Fill the second dialysis tube with 15 ml of the glucose solution.
6.Twist the pen end of each dialysis tube and tie in a knot. Try to have as little air as possible. Trim off the excess tubing.
7.Rinse the outside of both dialysis tubes with distilled water to remove any fluids that may have leaked out during the tying process.
8. Cut two equal lengths of string. Suspend each tube with string from the ring clamp.
9. Pour 250 ml of water into the small beaker. Add 5 drops of Lugol’s solution.
10.Pour 245 ml of the dilute Lugol’s solution into the large beaker, and test the solution for any presence of glucose using a glucose solution.
11.Suspend the dialysis tubes in the dilute Lugol’s solution so that they are submerged but do not touch the bottom of the beaker.

12. Pour the remaining 5 ml of dilute Lugol’s solution into a test tube and place in the beaker with the dialysis tube.
13. Pour 5 ml of the starch suspension into a second test tube and place in the beaker. Wait for 20 min.
14.While waiting construct a table similar to Table 1 in your notebook. Record your observations for the second column.
15. After the 20 min, complete the third column of your table.
16.Test dilute Lugol’s solution in the beaker and test tube for the presence of glucose. Indicate the color the glucose indicator changed. Add this information to your table.
What im doing is observing diffusion.
What is independant varible and dependant varible.

Is there one?? I cant figure it out help plz
