Glucose: Reference Range, Interpretation, Collection And Panels

Postprandial plasma glucose at 2 hours: Less than 140 mg/dL Random plasma glucose: Less than 140 mg/dL Serum glucose values are 1.15% lower than plasma glucose values. [ 1 ] Values for diabetes mellitus are as follows: Fasting plasma glucose: Greater than 125 mg/dL Random plasma glucose: Greater than 200 mg/dL Postprandial glucose at 2 hours: Greater than 200 mg/dL Impaired fasting glucose: Fasting glucose of 100-125 mg/dL Impaired glucose tolerance testing: Postprandial glucose at 2 hours of 140-200 mg/dL The value for hypoglycemia is as follows: Collect 0.5-1 ml of blood in gray-top tube containing sodium fluoride. For serum glucose, a red-top tube can be used. Serum is separated within 45 minutes of collection. For fasting glucose testing, collect the blood sample in the morning after an overnight or 8-hour fast. For postprandial glucose testing, collect the blood sample 2 hours after a regular meal. For oral glucose tolerance testing, after oral intake of 75 g of glucose, collect blood samples at 1 hour and 2 hours. For gestational diabetes testing, parameters are 1 hour after 50 g of glucose and 2 hours after 100 g of glucose. Glucose is a monosaccharide and is a primary meta Continue reading >>

    What does it FEEL like when your blood sugars are high?

    I know what the standard symptoms are for hyperglycemia and MOST of them are also symptoms of pregnany...which I am. So what are some tell-tell signs that your sugars are too high? I am already peeing, drinking, and hungry ALL THE TIME...so those don't count. I am also Moody (did anyone notice the capital M), have leg cramps, and am constantly tired...so those don't count either. I did my 1 hr GTT and FAILED MISERABLY, then did my 3 hr GTT and passed (yay), but am wondering if things have changed.
    Basically, it feels like I just slammed 4-5 Red Bulls...and not in the good way!!
    I never had these issues with my other two kids, but it has been over a decade since I've been preggers...

    Often there are no symptoms to high blood sugar. Other times there are. If your sugar is very high, you will lack energy because the glucose is in your blood and can't get into your muscles. Climbing stairs can feel like you are climbing a mountain.
    Increased thirst is another symptom although it's not one I had. Mention your symptoms to your doctor including your concern about high blood sugar. I was tested for diabetes when I was pregnant and it came back negative, but later when I gave birth to my son, he was over 10 lbs and they said I probably had gestational diabetes at the time.
    I was diagnosed with type II nine years later.

    I just want to repeat what someone else said - often, NO symptoms. that's why it's so important to test.

What is SERUM ALBUMIN? What does SERUM ALBUMIN mean? SERUM ALBUMIN meaning, definition & explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Serum albumin, often referred to simply as blood albumin, is an albumin (a type of globular protein) found in vertebrate blood. Human serum albumin is encoded by the ALB gene. Other mammalian forms, such as bovine serum albumin, are chemically similar. Serum albumin is produced by the liver, occurs dissolved in blood plasma and is the most abundant blood protein in mammals. Albumin is essential for maintaining the oncotic pressure needed for proper distribution of body fluids between blood vessels and body tissues; without albumin, the high pressure in the blood vessels would force more fluids out into the tissues. It also acts as a plasma carrier by non-specifically binding several hydrophobic steroid hormones and as a transport protein for hemin and fatty acids. Too much or too little circulating serum albumin may be harmful. Albumin in the urine usually denotes the presence of kidney disease. Occasionally albumin appears in the urine of normal persons following long standing (postural albuminuria). Albumin functions primarily as a carrier protein for steroids, fatty acids, and thyroid hormones in the blood and plays a major role in stabilizing extracellular fluid volume by contributing to oncotic pressure (known also as colloid osmotic pressure) of plasma. Because smaller animals (for example rats) function at a lower blood pressure, they need less oncotic pressure to balance this, and thus need less albumin to maintain proper fluid distribution. Albumin is synthesized in the liver as preproalbumin which has an N-terminal peptide that is removed before the nascent protein is released from the rough endoplasmic reticulum. The product, proalbumin, is in turn cleaved in the Golgi vesicles to produce the secreted albumin.

OBJECTIVES: Chronic infections with hepatitis B or C and alcoholic cirrhosis are three well-known major risk factors for liver cancer. Diabetes has also beensuggested as a potential risk factor. However, the findings of previous studieshave been controversial in terms of the causal association. Therefore, the aim ofthis study was to evaluate the association between serum glucose levels and livercancer development in a Korean cohort.METHODS: Thirty-six liver cancer cases were identified in the Korean Multi-CenterCancer Cohort (KMCC). Baseline information on lifestyle characteristics wasobtained via questionnaire. Serum glucose levels were measured at the study'senrollment. Relative risks (RRs) were estimated using a Cox proportional hazardregression model. The adjusting variables included age, gender, smoking history, alcohol consumption, body mass index, and hepatitis B surface antigen (HBs Continue reading >>

    Glucose Test, what was your sugar level?

    My doctor told me today that I failed my 1 hr fasting glucose test from last week, so now I have to do the 3 hour test.... Yuck!! Just wondering what everyone elses glucose levels came back as? My Dr said below 130 is normal and my levels were at 168!! I know a lot of the 1hr tests end up being false positives, but my level seems pretty high? I'm a little nervous becuz I love food and have a fear of dieting, lol Any other mommas have experience with GD?? What are your levels? Thanks!! : )

    I ate eggs and toast with milk for breakfast a few hours before my 1-hour, and my doctor told me last week that my number was 79.

    My one hour result was 209!!!!! Needless to say, they distance need a three hour test-- they til me I am definitely diabetic and now I'm taking insulin shots :/ just started yesterday... Hopefully you won't need to go that far, diet should just help. For me, cutting out sweet stuff wasn't enough :(

In this video I discuss what is fructose, fructose metabolism, and fructose in sugar. Transcript (partial) Fructose is a monosaccharide, which are the most basic units of carbs. Pure, dry fructose is very sweet, white, and odorless. It is found in honey, fruits, vegetables, sugar cane, and sugar beets. Usually fructose is separated from glucose in a sucrose molecule. It can then be added as a stand alone ingredient. Because pure fructose is sweeter than sugar, less of it can be used to achieve the same level of sweetness, which translates to lower calorie foods. 1 teaspoon of Pure dry fructose has 15 calories, which equates to 4.2g of carbs. How does the body use fructose? Most of the cells in our body cant process fructose, so,it is almost completely metabolized in the liver through a process called fructolysis. Essentially the liver converts fructose to energy, but, this energy cant leave because of its molecular makeup. The liver does burn off some of this energy . If there is any excess fructose after the energy conversion, the liver stores it as glycogen, which can be broken down into glucose and sent to other cells for use. But the liver can only store so much glycogen, once it is fully stocked in glycogen, the extra fructose is used to create triglycerides, which can be moved outside the liver for long term storage as fat. So, based on this, fruits must be bad? Actually, No, not at all. Fruits are loaded with water, fiber, and other nutrients, so, they take a while to eat and digest so, their fructose hits the liver slowly. The amount of fructose contained in fruit is much smaller than the added sugar in a soft drink for instance. Bottom linefructose is not unhealthy, depending on the source it came from. When that source is a natural food, like fruits and vegetables great, when that source is in the form of added sugar, not so great.

Effects Of Several Simple Sugars On Serum Glucose And Serum Fructose Levels In Normal And Diabetic Subjects.

Effects of several simple sugars on serum glucose and serum fructose levels in normal and diabetic subjects. Kim HS, et al. Diabetes Res Clin Pract. 1988. Department of Food and Nutrition, Sookmyung Women's University, Korea. Diabetes Res Clin Pract. 1988 Apr 6;4(4):281-7. Fructose has a reaction constant 7.5 times as high as that of glucose in its nonenzymatic reaction with protein in vitro. The effects of glucose, sucrose and fructose ingestion on serum fructose and glucose levels were studied to evaluate the overall biohazard, i.e., the probability of their altering proteins while circulating in the blood. Normal and diabetic subjects were given either 75 g glucose, 75 g fructose, 75 g sucrose, or 112.5 g fructose after fasting, and their serum levels of sugars were measured at 0, 1, 2 and 3 h. In normal subjects, fructose ingestion produced significantly lower serum glucose levels and significantly higher serum fructose levels than did glucose ingestion, while sucrose produced intermediate results. The glycemic effect was found to be lowest for fructose and highest for glucose. The calculated overall biohazard was, however, highest for fructose and lowest for glucose in normal Continue reading >>

    blood sugar dropped 80 points in an hour...any ideas?

    I had something odd happen last night and thought i'd better join a board and start learning more about my type 2. I was diagnosed about 1.5 years ago and have it pretty much under control using glargine at night, and metformin and glipizide before/during meals.
    I checked my blood at 9 p.m., took my 62 units of glargine and went to bed. it was 138. An hour later i was very hot, and got up to lower the temp. this was odd because it's the same temp it always is. i noticed i had a sheen of sweat on my forehead and i was feeling "shaky". i checked my blood and it was 58! Although i've had a large drop when i took the galipizide and didn't eat this was not the case!
    I did nothing different than any other time. I pretty much eat the same things. Any ideas as to what might have caused this drop? I drank some non diet pop and ate a bunch of fruit to bump it up.
    About 5 hours later (first thing when i woke up) i took blood again and it was about 135. two hours later, without eating/drinking it's up to 150 already.
    I'm 57, retired, and I'm with the VA for medical. I'm going to call the nurse later today.
    Thank you in advance! Have a nice day!
    one more thing. when i first got the blood sugar meds my morning blood was about 105. Now after bumping up the dosage over the last year and a half, my morning blood is around 130. Should I use more glargine to lower it to below 110 or is 130ish ok? I got mixed messages from the VA, or i've misunderstood!

    You received a reply about your fasting so, any exercise can cause the low (boy do I know about that one) so like did you exercise?
    Also, liver can and will dump when it thinks you haven't eaten lately and that would by why you went up without eating after 5-7 hours. Your liver is "helping". My liver helps too much some times, then forgets to help when I actually do need it...GAH.

  3. sstressed

    Exercise? exercise... huh.
    sorry, I don't recognize the word!
    I have a treadmill and i really need to take the books off of it!
    I didn't know that about the liver dumping if you don't eat for awhile. I have much to learn.
    I picked up a lot of bad eating habits over the last year. Good food, just too much of it! This has stopped as of today!
    I have searched for a couple of hours and can't find anything that points to why my blood sugar dropped so much so fast. I'll chock it up to just one of those things and hope it doesn't happen again.
    Thank you for your input! Have a good day!
