For those of you who are familiar with diabetes and the other factors related to diabetes, A1C level is the measurement of how good your body process blood sugar, or glucose, in your system, using its own insulin.
As explained above, normal A1C levels for a diabetics differ from country to country, and also differ from people to people. Recent Commentspatrice thompson on Free Diabetic Supplies – How to Get Them?munnaamalai on Type 1 vs Type 2 Diabetes ChartJessica I.
You are to calibrate the assay and use it to determine the concentration of glucose in the unknown solutions. You will also need to work out how to prepare and dilute the stock standard solution, and how to dilute the unknowns. Plan your experiment carefully and check your protocol with the Demonstrator before starting the assay.
Ideally you will have used the conclusions from each sheet to yield a biochemical diagnosis.
The MCQ card must be handed in to the teaching laboratory staff for marking together with the write-up for the experimental part of the this practical before 4:30pm on the Friday of the following week. In infancy, the patient was liable to convulsions if food was not given at frequent intervals. Glucagon (1 mg) was administered intramuscularly at time zero to the control and the patient and blood sugar measured at 30 min intervals thereafter.
1 g galactose or 0.5 g fructose (as indicated on graphs) per kg body weight is infused intravenously and the blood glucose concentration is followed.
Carbohydrates - it doesn't matter whether these are sugar, jam, bread, pasta, breakfast cereals or fruit - are all exactly the same as far as your body is concerned: they are all converted to the blood sugar, glucose. High blood glucose levels are harmful to the body and, as levels of glucose rise rapidly in the bloodstream, your pancreas produces a large amount of insulin to take the excess glucose out. There is a further aspect to be considered: There is an inevitable time delay between cause and effect. During this, your blood sugar levels are fluctuating wildly - you are 'yo-yo dieting' by the hour.
Not surprisingly, a 'healthy' carbohydrate-based diet, whether or not it is low-GI, gives by far the worst control of blood glucose and insulin levels. The next problem is that insulin resistance caused by the continual high levels of insulin in your bloodstream impairs the insulin's ability to satisfy a satiety centre in your brain. A great book that shatters so many of the nutritional fantasies and fads of the last twenty years.

If you want to know the number for normal A1C levels for diabetics, you have come to the right place. This glycated hemoglobin will exist for around 120 days, that is why usually A1C test is good for 3 months.

It is therefore important that no other reactant is limiting and that adequate time is allowed for the reaction to occur. Depending on the assay, the upper limit may be determined by the availability of other reagents, or by the magnitude of the readings obtained, e.g.
This is particularly important in the setting of a clinical chemistry laboratory where the results of biochemical analyses are used by clinicians to determine treatment etc.
To assess the accuracy of a result obtained from a biological sample it is necessary to use another assay to measure the "true value". It is also important to ensure that biological samples are processed appropriately once they are obtained so that no loss or gain of the analyte occurs between sampling and assay. If any other component in the sample also causes a change in the measured variable, the assay is not specific and will also not be accurate.
Some of the results obtained will then be used to assess the accuracy and precision of the assay. You may discuss the results on each sheet with your group, however please fill in the comments on each sheet individually.
I know this is heresy to the 'healthy eating' dictocrats, but why it should be is a mystery: as long as humans have been raising animals for food, we have fattened them on carbs. It is converted first to a form of starch called glycogen which is stored in the liver and muscle cells.
This means that within a very short time after a carb-rich 'healthy' meal the level of glucose in your bloodstream will rise rapidly.
The answer is to eat less carbohydrate so that the blood sugar level does not fluctuate so violently, and eat more fat.
You will note that insulin levels after a carb-rich meal don't return to normal for some 4 hours. Eating the 'healthy' way, you can eat far more calories than your body needs as energy for the day, yet still feel hungry - and eat more. Once you have had the lucozade drink a second blood sample from your arm will be taken after 2 hours. If there is a lack of insulin, or your body does not react well to insulin in such a way that its effectiveness in lowering the blood sugar is compromised, then your blood sugar level will remain high. So we have to take all these information with a grain of salt simply because these numbers are only indication. However, whatever your A1C level is, you must know how it works in order for you to understand what you need to do to handle it properly. After that your body will start to regenerate the red blood cells and the new blood cells will have a different A1C measurement since it will have a different level of glycated hemoglobin in it. It usually involves testing a range of concentrations of the analyte, although where the linearity of the relationship has been established previously, a single standard solution may be used. However, this approach should only be attempted if you are confident that the second assay is giving accurate results.
You will be left to work out this problem on your own but you may ask your Demonstrator for advice. But as the body can store only a limited amount of glycogen in this way, all the other excess glucose is stored as body fat. Figure 1a shows that a high-carb meal increases blood glucose dramatically whereas a high-fat meal has practically no effect at all.

This drives glucose in your blood abnormally low (it's called reactive hypoglycaemia ) and you soon feel hungry again. Because it takes a long time to digest, fat not only prevents those violent fluctuations in blood sugar levels, it gives a feeling of satiety, which stops that feeling of hunger.
Extended effects of evening meal carbohydrate-to-fat ratio on fasting and postprandial substrate metabolism. It means that when you have a sugary drink or foods your body is unable to processes it quickly enough and your blood glucose is still above normal two hours later. It has to be reviewed together with your lifestyle and habits and consulted with your doctor and dietician. So for instance if you have a 6.0 A1C test result, this test result will be good for about 3 months. Alternatively, if the relationship between the measured variable and the concentration of the metabolite is only linear over a limited range, it may be appropriate to class the upper limit of the assay as the point where proportionality ceases to apply. If there is no means of measuring the true concentration of the analyte in a sample, then some indication of whether an assay is giving accurate results can be obtained by "spiking". The reason is because some people who also have problems with their cholesterol and blood pressure, will be at risk for other problems when their A1C test shows a high number. That is why it is quite common for doctors to suggest A1C test to be done at least twice a year, and more frequently if deemed necessary.
The lower limit of an assay is not zero, but is the point below which results become too variable to be meaningful, i.e. In this process, the sample is assayed and is then spiked with a known amount of the analyte and re-assayed to see whether the obtained result has increased as predicted. Provided no contaminants are reacting, the reading should be equal to that given by the reagent blank. Where a standard curve is to be set up, concentrations should be chosen that are uniformly distributed across the range of the assay. If it is not possible to selectively remove the analyte from the sample, the specificity of an assay may be checked by testing potential contaminants directly. To ensure that you have interpreted the results correctly, your Demonstrator will hold a 30 - 60 minute tutorial at 3pm, during which you will get a further 2 sheets to complete the data set, plus a computer-marked MCQ on the topic, which will be assessed. In many cases, the relationship between the measured variable and the concentration of the analyte can vary slightly between assays, e.g. It is recognised that more complex assays are likely to be less precise (errors are cumulative), and hence the number of steps in an assay is taken into account in determining acceptable values for the C.V. However, this is time consuming, relies on being able to identify all potential contaminants and does not assess their contribution within samples. Problems with specificity may sometimes be overcome by adjusting the assay conditions so as to minimise the extent to which contaminants react, or by removing them from the sample prior to assay.
If precision is poor, the sample will have to be assayed more times to ensure that the mean result obtained is representative of the true mean value, i.e.
