The Chemcard? Glucose Test is an easy to use home screening test to identify high glucose or blood sugar levels. Diabetes can affect every organ system in the body, and is the leading cause of preventable blindness, lower extremity amputation, and end-stage renal disease. The American Diabetes Association recommends that all adults over the age of 45 receive a glucose test annually. The Chemcard Glucose test - recommended for nondiabetics to measure the glucose level of your blood to make sure that you are not at risk.
The Hemoglobin A1c test - recommended for known diabetics to help make sure that your diabetes is under control.
As recommended by the ADA, Chemcard? Glucose measures plasma glucose level after a minimum fasting period of 8 hours. The mostly benign tumor is found twice as often in female patients as compared to male patients.
For decades this test is established as the gold standard in the endocrinological diagnostic work-up of hypoglycemia.
Usually the test has to be performed on an in-patient basis requiring a specialized and trained hospital setting. Many endocrinologists omit the oral glucose load before a fasting test due to a misconception when both tests are being viewed at independently. An oral glucose loading test performed before or after a fasting test on a different day is superfluos and not indicated.
The fasting test reflects a classical endocrinological suppression test in the situation of potential hyperinsulinemia.
Suppressibility of the ambient insulin concentration to normal levels ( adaequate insulin secretion in the normal situation or inadaequate secretion in insulinoma ) right after a glucose-induced stimulation with oral 75-100 g of glucose is being tested.
Thus, a standardized condition may be created allowing correct interpretation of the test already early into the test phase by the endocrinologist. We start every fasting test in the morning after overnight fast by means of oral administration of 100 g of glucose = last defined meal at a known time point. No advantage has been shown with the intraarterial calcium infusion (stimulation) test (SIPS) which is propagated mainly in the U.S. Besides logistics the correct interpretation of fasting test results is of fundamental importance for a correct diagnosis (insulin - secretion) - misinterpretations often are the cause of a doubtful or even wrong diagnosis.
The reproducibility of typical insulin and blood glucose levels, especially before discontinuation or at the end of the fasting test should be of prime concern.
Valid studies addressing follow-up of patients with an earlier negative result in the fasting test so far have not been done. The A1C test is a blood test that reflects the average blood-glucose level over the last two to three months. In 1950s, hemoglobin A1c was identified as one of the largest fractions of the minor components of normal adult hemoglobin. Hemoglobin is a protein in the red blood cell, which transports oxygen from your lungs to the whole body. HbA1c is a simple blood test measures the percentage of hemoglobin variant “A’ subtype ‘1c” that has been attached to the glucose in the blood. However, blood-glucose levels in the preceding 30 days can make more effect in the A1C than the 90 to 120 days earlier. If you are having A1C percentage, it looks less meaning, until you convert it into equivalent blood-glucose level help provide more meaning. HbA1c tests can easily do with a regular finger stick or a blood sample drawn from a vein in your arm like testing for blood glucose. Laboratories should be aware of their method limitations with respect to interference from the most prevalent Hb variants.
Decrease or increase in erythrocyte (decrease in RBC) can make you A1C to lower or increase respectively.
Hb Variants - Hemoglobin S trait, which affects about 8% of African Americans, hemoglobin C trait, which affects approximately 3% of African Americans, and hemoglobin E trait, which affects 10% to more than 50% of Southeast Asians in California, are all reported to affect some HbA1c assay methods. Vitamin C & E ingestion interfered with some assay methods and falsely decreasing results. A splenectomy is a surgical procedure that partially or completely removes the spleen, will falsely raise A1C. Bone marrow conditions - include leukemia, multiple myeloma (cancer of the plasma cells in bone marrow), and lymphoma (blood cancer).
Nutritional deficiencies such as iron, copper, foliate vitamins B6 and B12 can falsely affect the result.
Once A1C interferences are recognized; choosing an alternative form of testing, such as glycated serum protein testing (fructosamine or glycated albumin) can help assess glycaemia better. Many people have a question, what does it mean if I have a high A1C and normal blood sugars?
Diabetic’s Institute Pakistan (DIP) Is The Leading Organization For Diabetes Management, Treatment, Education And Counseling In Pakistan. This is important to diabetics as the higher the HbA1c, the greater the risk of developing diabetes-related complications. When human body processes sugar, glucose in the bloodstream naturally attaches to haemoglobin.  The amount of glucose that combines with this protein is directly proportional to the total amount of sugar that is in the system of human body at that time.
It is because red blood cells in the human body survive for 8-12 weeks before renewal, measuring glycated haemoglobin (or HbA1c) can be used to reflect average blood glucose levels over that duration, providing a useful longer-term gauge of blood glucose control.
Since blood glucose levels fluctuate constantly on a minute by minute basis, regular blood glucose testing is required to understand how the levels changing through the day in order to learn how different meals affecting glucose levels. On arrival, subjects were weighed and the body composition assessed by bio-electrical impedance (Imp Df 50; ImpediMed, Pinkenba, Australia).
Over the 6 h following Fr + G ingestion, 33% of the ingested fructose was oxidized to CO2, and the remaining 67% was disposed of non-oxidatively (Table 3).


Total glucose rate of appearance (GRa, n = 8), fructose oxidation, total net carbohydrate oxidation (total carbo. HbA1c is a widely used marker of chronic blood glucose levels, reflecting average values over a two to three month period. For decades, the diagnosis of diabetes has been based on blood glucose tests, either the fasting plasma glucose or the 75-g oral glucose tolerance test.
HbA1c is a chronic marker of high blood glucose and it is already widely familiar to clinicians as a marker of glycemic control.
Providing health care professionals with another tool to identify undiagnosed cases of diabetes should help them identify and manage people with diabetes before the complications appear. This E-book will provide you with exclusive tips and the knowledge necessary to prevent and control high blood pressure.
A significant portion of the adult population in the US between the ages of 20 and 74 suffers from undiagnosed diabetes mellitus. Persons with diabetes are also at an increased risk for hypertension, stroke and heart disease. Among those most at risk are overweight people over 40 who do not exercise, African Americans, Hispanics, Native Americans, and those with a family history of diabetes. This test can identify individuals with abnormal blood glucose levels which is often associated with diabetes or other carbohydrate metabolic disorders. This occurs regularly in every individual between daily meals, but predominantly during night rest. Followed by different discoveries and in 1976, Koenig and colleagues demonstrated that HbA1c concentration was an indicator of fasting blood-glucose concentrations.
Elevated hemoglobin F, which is associated with thalassemia syndromes, also affects some assay methods.
Unfortunately, factors affecting the accuracy of HbA1c measurement may not be recognized clinically. Many others, on the other hand, have a question, what does it means if I have normal A1C and high fasting glucose? This may however not be relevant to typical nutritional situations, where fructose is invariably ingested with glucose. Study DesignEach volunteer was studied on three different occasions according to a randomized cross-over design.
Subjects were asked to void their bladder, and the collected urine was discarded, with all urine thereafter collected until the end for the determination of the urinary urea nitrogen excretion rate. Effects on Carbohydrate MetabolismAfter ingestion of Fr + G, plasma glucose and insulin increased rapidly, peaking after 150 min, and, thereafter, declined progressively.

Learn about healthy eating, nutrition, heart disease, hypertension, diabetes, high cholesterol and much more from the true experts. The test plays a critical role in the management of the patient with diabetes since it correlates well with both microvascular and, to a lesser extent, macrovascular complications. In a 2009 report, an International Expert Committee recommended the use of the HbA1c test to diagnose diabetes, with a threshold of 6.5%, and the American Diabetes Association sustained this decision. Food and Drug Administration, in May 2013, approved the marketing of the COBAS INTEGRA 800 Tina-quant HbA1cDx assay (Roche) for the diagnosis of diabetes by health care professionals. Health care providers can use it to both accurately diagnose diabetes and to monitor blood glucose control. Moreover, the HbA1C has several advantages to the fasting plasma glucose, including greater convenience since fasting is not required, evidence to suggest greater stability before the analysis and less day-to-day variations during acute stress and illness. A sterile disposable lancet is used to obtain a single drop of blood which is placed onto the "Test Area". J Pancreas 2002) has apredominant role in the diagnostic exclusion of insulinoma, when the disease seems to be highly unlikely. The blood-glucose level decides the volume of glycosylation reaction and the level of glycated hemoglobins. Home tests are now available too; they are subject to inaccuracy, if not conducted exactly as stated in the instructions.
As with any laboratory test, any result that does not fit the clinical picture should require investigation further with the clinician. We therefore assessed the metabolic fate of fructose incorporated in a mixed meal without or with glucose in eight healthy volunteers.
On each occasion, participants first consumed a controlled weight-maintenance diet (basal energy requirements calculated with the Harris-Benedict equation times a physical activity factor of 1.5) containing 55% carbohydrate (35% complex carbohydrate and 20% sugar), 15% protein and 30% fat during 3 days.
Subjects were then transferred to a bed, where they remained quiet, but awake for the next eight hours.
The normality of data and differences was checked with Shapiro-Wilk tests for all parameters analyzed. With Fr, total GRa, cumulated over six hours postprandial, was lower, but GNGf, cumulated over the same period, was higher than with Fr + G.
The HbA1c tests currently on the market are approved for monitoring a patient’s blood glucose control, but not for diagnosing diabetes. They recommended a test certified by the National Glycohemoglobin Standardization Program (NGSP) and standardized or traceable to the Diabetes Control and Complications Trial reference assay. This test should not be used to diagnose or monitor diabetes in patients with the hemoglobin variant F. After three minutes, the top layer of the card is peeled off and the results obtained by matching the color of the test area with a sliding color chart.

There is much concern that this may contribute to the rise in prevalence of obesity and metabolic disorders observed over the same period [3].
During this period, they were asked to have minimal physical activity and to abstain from alcohol or caffeine-containing beverages.
Non-normally distributed data (glucagon, TG, VLDL-TG) were log-transformed before statistical analysis.
Plasma lactate and 13C-lactate concentrations also increased significantly and showed the same time-course as glucose (Figure 3). Cumulated fructose oxidation was also significantly higher and corresponded to 37% of ingested fructose, while non-oxidative fructose disposal was lower (Table 3). Plasma NEFA decreased transiently after ingestion of the meal and, thereafter, progressively increased. However, HbA1c tests were not specifically designed or approved by FDA to be marketed for diabetes diagnosis, making it difficult to determine which HbA1c tests were accurate enough for this purpose. In order to grant the approval, investigators analyzed 141 blood samples and found a less than six percent difference in the accuracy of test results from the Tina-quant HbA1cDx assay compared to results from the standard reference for hemoglobin analysis.
Upon matching colors, the test card is turned over and the result appears on the back side of the test card.
Today, DIP Continues To Provide World-Class Diabetes Care, Education, Publications And Research That Meet The Needs Of Patients And Their Families. This is mainly based on the observation that a high-fructose-containing diet causes obesity, diabetes mellitus, dyslipidemia and hepatic steatosis in rodents [4,5] and that short-term fructose overfeeding increases fasting and postprandial triacylglycerol (TG), decreases hepatic insulin sensitivity and increases intrahepatic fat in humans.Several short-term studies, using 13C-fructose as a metabolic tracer, have documented that fructose exerts specific metabolic effects, which may indeed contribute to the pathogenesis of insulin resistance and dyslipidemia. All variables measured at different time points after ingestion of test-meals were reduced to a single value by calculating their average or cumulated postprandial values (gluconeogenesis from fructose, fructose oxidation, glycogen synthesis, net substrate oxidation, energy expenditure) or their cumulated incremental area under the curve values (iAUC: plasma concentrations of metabolites or hormones) over the 360-min postprandial period.
Fructose is largely extracted by splanchnic organs (gut and liver), where it is essentially converted into glucose, lactate and fatty acid, which can subsequently be used as an energy substrate by extrahepatic cells. Fructose was labelled with 1% U-13C6-fructose (Cambridge Isotope Laboratories, Tewksbury, MA, USA). Respiratory gas exchange was monitored throughout the experiment by open circuit indirect calorimetry (Quark RMR, version 9.1b, Cosmed, Rome, Italy). Between test-meals, comparisons were performed on these single postprandial values by ANOVA followed by pots hoc paired t-tests with Bonferroni’s correction.
Over the six hours after meal ingestion, since the enrichment of fructose in the meal was set at 1 mol% excess, this indicates that fructose contributed to approximately 15% of the total lactate production.After Fr, the increase in plasma glucose and insulin concentrations was markedly blunted compared to Fr + G (Figure 2). With Fr, plasma TG, VLDL-TG and chylomicron-TG plasma apoB48 and plasma apoBtot responses were not significantly different from Fr + G. Energy expenditure and net substrate oxidation were calculated using the equations of Livesey and Elia [19].
These data indicate that gluconeogenesis, lactic acid production and both intestinal and hepatic de novo lipogenesis contributed to the disposal of fructose carbons ingested together with a mixed meal. The oxidation of these newly synthesized substrates obviously contributes to total breath 13CO2 production, but the relative amounts of 13C glucose being immediately oxidized in extra-hepatic tissues and stored as extra-hepatic (mainly muscle) glycogen is not known. Due to technical problems, results could not be obtained for 2 subjects during one of the three meals. All statistical analyses were performed using STATA version 10 (Stata Corp, College Station, USA). Plasma lactate and glucagon concentrations and plasma 13C-lactate isotopic enrichment were also not significantly different than after Fr + G (Figure 3).
Co-ingestion of glucose decreased fructose oxidation and gluconeogenesis and tended to increase 13C-pamitate concentration in gut-derived chylomicrons, but not in hepatic-borne VLDL-triacylglycerol (TG). After intravenous administration, hepatic and muscle glycogen synthesis account each for about 25% of total fructose infused [9], but similar data are not available for oral fructose administration. Data collected during the other two meals in these two subjects were not taken into consideration to avoid introducing bias in paired statistical analyses. VLDL-TG, chylomicron-TG and plasma ApoB48 concentrations did not show any significant differences with Fr + G or Fr (Figure 5 and Figure 6). Labelled carbon atoms are also recovered as very low density lipoprotein VLDL-fatty acids, indicating that hepatic de novo lipogenesis is active after fructose ingestion [10].
Blood samples were collected at Time 0 immediately before starting the 6,6-2H2-glucose administration (T = 0 min) and after two hours spent in fasting conditions (T = 120 min); thereafter, subjects consumed their test meal over a 15-min period (T = 120 min), during which indirect calorimetry was interrupted and blood samples were collected at T = 150, 180, 210, 240, 270, 300, 360, 420, 480 min.
Tracer studies using 13C-acetate as a lipogenic precursor further indicate that fructose is substantially more lipogenic than glucose [11]. The order of administration of the three meals was randomized, and a washout period of 3–10 weeks was allowed between metabolic tests. De novo lipogenesis is generally assumed to occur in the liver, but may also take place in the gut [12,13]. Breath samples were collected for the measurement of 13CO2 isotopic enrichment at T = 0, 60, 120, 180, 240, 300, 360, 420 and 480 min when subjects had the Fr and Fr + G meals, and at T = 0, 120, 240, 360 and 380 min when they had the ProLip meal.
It is enhanced by the consumption of a high fructose diet [14], and contributes, together with a decrease of TG-rich lipoprotein clearance [15,16], to fructose-induced hypertriglyceridemia.The relevance of studies assessing the effects of pure fructose on the pathogenesis of metabolic diseases is often questioned, as dietary fructose is mainly present in fructose-containing caloric sweeteners (sucrose, high fructose corn syrup), fruits and honey, which all contain roughly equimolar amounts of fructose and glucose. Co-ingestion of glucose or other nutrients may indeed significantly alter the metabolic fate of fructose due to changes in glucoregulatory hormone concentrations.
In addition, glucose and fructose are expected to mutually enhance their splanchnic metabolism, since the presence of glucose in the gut lumen increases intestinal fructose absorption, on the one hand [17], and fructose-1-P activates hepatic glucokinase, resulting in hepatic glucose metabolism and glycogen storage, on the other hand [18].
The aim of the present study was to assess the metabolic fate of fructose and its interaction with other nutrients present in a mixed meal. For this purpose, we monitored, in healthy human volunteers, the metabolic response to a liquid meal containing protein, fat, glucose and 13C-labelled fructose and to the same liquid meal in which glucose only or both glucose and fructose were omitted. These measurements were performed after subjects had consumed a weight-maintenance diet containing 20% sucrose for three days.
