Is It Possible For Someone To Have Abnormally High Plasma Glucose Concentration And Yet Not Have Glycosuria
1
Is it possible for someone to have an abnormally high plasma glucose concentration but not have glycosuria?
Yes: The threshold for glycosuria is blood sugar of around 200 so the blood test is more sensitive for detecting diabetes. ...Read more
Blood Sugar (Definition)
The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily ...Read more

Could a large carb intake cause a large increase in plasma glucose concentration?
Yes: Hi. Carbohydrates are polymers of sugars, and get broken down to sugars (except fibers, which are carbohydrates humans can't break down). If you're not diabetic, a "large" carb intake won't produce a "large" increase in blood glucose, but it can if you're diabetic. Eat healthily and exercise regularly. Good luck! ...Read more

What could cause plasma glucose to be 10 - 15% higher than whole blood glucose concentration?
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. ...Read more

Why would a patient with pancreatic cancer show increased levels of plasma glucose concentrations?
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. ...Read more

Is it true that during a large meal there is a large rise in blood glucose concentration and a small production?
Blood glucose: Blood glucose is not likely to rise during a large meal, but a large meal is not always a good idea. ...Read more

Why do diabetics need to know their blood glucose concentration?
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. ...Read more

What's the reason for the increase of glucose concentration throughout the day?
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. ...Read more
8
What's the mechanism that prevent glucose concentration dropping too low?
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. ...Read more

What are the urine findings be for someone with a 500 glucose concentration?
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. ...Read more

What's a glucose concentration like in diabetics?
Diabetes: Any or all of the following: fasting blood sugars of > 125mg/dl, 2 hour post prandial blood sugars of >199 mg/dl, or blood sugar of at least 300 mg/dl at any time are criteria for the diagnosis of diabetes mellitus. ...Read more

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?
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.

My mean plasma glucose is 111; hba1c is 5.3. My doctor said I don't have diabetes, but isn't my glucose high?
No:
A1c between5.7 to 6.5 indicated pre diabetes.
> 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.

13
What does it mean if your plasma glucose levels are only high on a fasting blood test?
Unclear question: Did you have a glucose tolerance test and only the fasting glucose was high? How high was it? Fasting plasma glucose is 100-125 it is pre-diabetes and 126 or higher, if noted on two occasions is diagnostic of diabetes. ...Read more
14
I'm 40 year old my fasting plasma glucose is 6.0 I want to know if it is high or low?
High: I assume the 6.0 refers to mmol/l, a measurement typically used in europe. In the us, this would be 108 mg/dl. A fasting glucose above 100 mg/dl (5.5 mmol/l) is considered high. If it is above 125 mg/dl (7 mmol/l) it is consistent with diabetes. ...Read more
15
I'm 40 years old my fasting plasma glucose is 6.0 it is normal or high?
Not normal: Fasting glucose of 6 mmol/l is equal to 108 mg/dl which put you in the pre-diabetes range (100-125 mg/dl). If this is the first time you see this, repeat it again to see if this was not just a lab error. If you truly worries about diabetes, ask for a a1c test on the next blood draw as well. This test is more stable and give an average of your last 3 month blood sugar. ...Read more

I got 179 mg in plasma glucose post prandial. Can I have diabetes?
Impaired Tolerance: A blood sugar of 179 mg/ dl 2 hours after a meal or ogtt is in the diagnostic range of impaired glucose tolerance, pre-diabetes. This condition places patients at high risk for developing diabetes and is treated by physicians. Lifestyle modification is the most important aspect of treatment in order to avoid further progression to disease. ...Read more

Doctor, I am 43 yrs old n my fasting plasma glucose is 102mg/dl and my post lunch plasma glucose is 149mg/dl, is it normal?
FASTING:
Your fasting bs is normal, although some physicians believe that it should be under 95.
A 2 hours post pandrial bs ideally should be under 120. A level of 149 is slightly elevated but not to be concerned.

Is an mean plasma glucose of 136 with an a1c 6.0 within normal range>?
Slightly eleváted la:
I don't know if your glucose was a fasting level or not. If it was a fasting level it was slightly elevated. The Hgb A1c meàsures long term glucose control and should be below 5, 7.
So these tests both indicate that you have issues with glycemic control.

Is fasting plasma glucose test by itself good enough to diagnose diabetes?
No: Diabetes is diagnosed based on several criteria. One test is the fasting plasma glucose test, but this should be confirmed with a second elevated fasting glucose test. A glucose challenge test or a hemoglobin A1c test may be substituted as well. ...Read more

Fasting Plasma Glucose test reports HB A1c [HPLC] as 5.80% (5.7-6.4) and says "per-diabatic". What are some diet and lifestyle recommendations?
Low carb/grain diet: Cut our grains/limit starches and increase good fats (olive oil, avocado, nuts). have good animal based protein intake (including organic eggs and fish). A1C of 5.8% is indeed in the impaired range and should normalize with the above diet and 10-20% weight loss if extra weight is present ...Read more

Why does the level of plasma glucose rise after a meal?
Food is energy: Eating food will provide your body with energy to function. Simple sugars will increase the blood sugar quickly. Carbs and starches will increase it more slowly. Proteins will have the least impact on blood sugar. ...Read more

1/23/16 A1c 5.3% Fasting 84 Estimated Mean Plasma Glucose 90. Lost 12 lbs. No sugar diet. Ate very healthy but not a lot of calories. 7/25/16-A1c 5.9%. Fasting 79. Est. Mean PlaGlucose 110.47 Nondiabetic-why did they rise? I am 51, 121lbs 5'4 worried!
Lab numbers Fluctuat: The blood test number tend to fluctuate from one time to other. So I do not think your sugars or A1C are any worse now than they were in Jan 2016. As long as your Fasting blood sugar is staying under 100, you are safe. But in the meantime, continue your increased physical activity daily. That will keep you healthy. Recheck your sugar and A1c in 6 months from now and perhaps once yearly thereafter. ...Read more

A1c 5.2, CPeptide 1.5, Insulin level 4.3 uIU/mL, Estimated Mean Plasma Glucose 87.16. Fasting was 79. Was told to start Metformin...why? Do these numbers mean I am diabetic? Afraid to eat certain foods now.
Is that so?: Glucose and A1c are fine. I would get a second opinion. This does not say "diabetes" to me. Food choices are not the key to managing diabetes in any case. Stay physically fit and get with another physician. ...Read more

My baby is big but my plasma glucose test is normal as well as the others. Why?
Large for gestationa: The mother has a large for gestational age infant. This is sometimes due to gestational diabetes. At times it is because of maternal overweight or the development of gestational diabetes in the future pregnancies. Even if the mother has normal fasting glucose, she should have glucose tolerance test and hemoglobin A1c to confirm that she does not have type 2 or gestatational diabetes. ...Read more

What does it mean on a A1c where it shows a 6.1 for value and then mean plasma glucose of 140 being normal?
Repeat test: The A1C test result reflects your average blood sugar level for the past two to three months. For someone who doesn't have diabetes, a normal A1C level can range from 4.5 to 6 percent. A result between 5.7 and 6.4 percent is considered prediabetes, which indicates a high risk of developing diabetes. When the test is used to diagnose, a level of 6.5 percent or more on 2 occasions is diagnostic. ...Read more
