Question 1

is it possible for someone to have an abnormally high plasma glucose concentration but not have glycosuria?

Accepted Answer

Yes: The threshold for glycosuria is blood sugar of around 200 so the blood test is more sensitive for detecting diabetes.

Question 2

what could cause plasma glucose to be 10 - 15% higher than whole blood glucose concentration?

Accepted Answer

Proportions : Plasma has more liquid in it than whole blood. Glucose is dissolved mostly in the plasma component of blood. Whole blood has less of the liquid in it and therefore will have a lower glucose concentration than plasma.

Question 3

why would a patient with pancreatic cancer show increased levels of plasma glucose concentrations?

Accepted Answer

Sometimes: Yes, because pancreas contain cells that produce insulin.  If the cancer is advanced enough, these cells too get affected.  But these are general statements that the possibility exists.  Ask your doctor for specific recommendations.

Question 4

why do diabetics need to know their blood glucose concentration?

Accepted Answer

Monitor Control: Blood sugar can change from one point in time to the next. A hba1c won't elaborate on what got it there. Testing blood sugars allows patients and doctors to decide how to adjust medication or when one needs to start taking medication. Particularly at the extremes, knowing blood sugar can prevent trouble with very high or low blood sugars.

Question 5

what's the reason for the increase of glucose concentration throughout the day?

Accepted Answer

Post prandial: After eating, there's an inevitable mild blood sugar increase as glucose enters the system, but normally this increase is physiological and expected. It is also short-lived. It signals the body that fuel is available so that other hormones can be released to help use and store the intake of energy.

Question 6

what's the mechanism that prevent glucose concentration dropping too low?

Accepted Answer

Hormones: Called counter regulatory hormones tend to resist the severe drop of bs. Such hormones include cortiol, Epinephrine and growth hormone. You also have the liver act as a reservoir of glycogen that can be broken down into glucose in times of need such as acute hypoglycemia or during prolonged fasting.

Question 7

what are the urine findings be for someone with a 500 glucose concentration?

Accepted Answer

You would see: A lot of glucose in the urine and a higher urine volume. Forget the urine for now, however. If your glucose is 500, you need to seed immediate medical attention and get on proper therapy to lower your glucose to safer and more normal levels.

Question 8

my gp said my urine was positive for glucose, but the amount wasn't significant. my urologist looked at the same report & said he didn't see anything wrong. what could be the case? who's more qualified to detect glycosuria? i'm scared about diabetes?

Accepted Answer

: It is either positive or negative. And both are significant. Glycosuria is a plain result which comes from the lab with result- positive or neg. So there should be no interpretation involved by either MD

Question 9

have gtt test. blood glucose normal. o hour and 1 hour urine glucose negative but 2 hour urine glucose is trace. false positive or renal glycosuria?

Accepted Answer

Urine glucose: If your GTT is OK and the 2 hour urine only a trace high, I don't think you have anything to worry about.
That said, be careful with your food and drink intake.

Question 10

my mean plasma glucose is 111; hba1c is 5.3. my doctor said i don't have diabetes, but isn't my glucose high?

Accepted Answer

No: A1c between5.7 to 6.5 indicated pre diabetes.
&gt; 6.5 indicates diabetes. Having said that diabetes is more like a gradient disease- by that what i mean is with an a1c of 5.3 your risk of diabetes is  slightly higher than a person with a1c of 4.8.
Life style modifications with diet and exercise will decrease this risk.
