Glucose tolerance test

Introduction The oral glucose tolerance test (OGTT) is used to measure the response of the body to glucose. More specifically, the test has been used for decades in the clinical as well as experimental environment as an ‘index of the efficiency of the mechanisms regulating the concentration of glucose in the blood’ (Baird et al., 1959). It has proved to be an important tool in the diagnosis of diabetes mellitus, and is commonly used in the screening of gestational diabetes in women. Diabetes mellitus

PART 1: Questions 1. Describe the following serum glucose tests used to help diagnose diabetes mellitus: fasting, postprandial, and oral glucose tolerance test. Diabetes Mellitus is an endocrine disorder characterised by the body’s inability to produce insulin or the ineffective use of insulin present in the body. The major classifications include type 1, type 2, and gestational diabetes (Day, Paul, & Williams, 2016). While early signs and symptoms of diabetes mellitus may be present in individuals

Introduction: Glucose is one of the few chemical constituents of the blood that can change noticeably in its concentration. Many diseases cause a change in glucose metabolism but the most frequent cause of an increase in blood glucose is diabetes mellitus. The early detection of diabetes is important to avoid the many complications of the disease. The glucose tolerance test commonly done by recommended level for adults of a 75 g glucose drink to be consumed within a 5 min time period. The timing

Glucose tolerance test is one of the ways to monitor diabetes it evaluates a how individuals body controls the level of sugar. It helps to monitor diabetes and gestational diabetes of pregnant women. Before taking a blood is taken an individual is asked not to eat or drink up to 12 hours. Moreover, for the individual with type 1 could monitor the blood glucose by the healthcare professional from two to six months. Also, the patients could monitor their own blood glucose level at their home. A blood

Why am I having this test? The glucose tolerance test (GTT) is done to check how your body processes sugar (glucose). This is one of several tests used to diagnose diabetes that develops during pregnancy (gestational diabetes mellitus). Gestational diabetes is a temporary form of diabetes that some women develop during pregnancy. It usually occurs around weeks 24–28 of pregnancy and goes away after delivery. You may have the GTT test after having a 1-hour glucose test with results that indicate

person’s ability to handle a certain load of glucose, thus it is important that they have not eating anything that will interfere with the results. Initially, a fasting glucose blood tested is performed. If an individual has high resting blood glucose level, it indicates that their body is unable to produces insulin to regulate normal level of blood glucose. After administrating a small glucose dose, it takes approximately 2 hours for blood glucose levels to return to normal, and much longer to

To investigate blood glucose concentrations following food input. This was done by analysing blood glucose concentration data from individuals ingesting various types of food following several hours of fasting. To also examine glucose tolerance test in a clinical context and to further explain glucose concentrations in the body. Results The students who continued fasting after the 12hr fasting period has almost equal amounts of blood glucose concentrations (BGC), during the 90mins period, with

This test indicates to the doctor whether or not the body is processing glucose correctly. Diabetes is diagnosed with this test if after two hours the blood glucose level is greater than or equal to 200 mg. There is also a Random Plasma Glucose Test, which is a blood test that can be done at any point in the day when experiencing diabetic symptoms (American Diabetes Association, 2013).

of fasting blood glucose levels subjects in the oral glucose tolerance test consumed a 10 ounce beverage that contained 100 grams of glucose. Over the next 2 hours subjects repeated the same method as used in the control test to test their blood glucose levels 4 more times. These 4 tests were conducted at 30 minute intervals and all readings were recorded for later examination. Physical Exercise Test After recording their fasting blood glucose levels subjects in the exercise test group transitioned

up with the use of glucose standards prepared in the first part of the experiment with the absorbance readings plotted on the Y axis and concentration on the X axis. This standard curve can then be used to help plot and find unknown concentrations for the patient and control samples, it also allows us to determine the equation of the line (y) and the correlation coefficient (R2) which were 2.2447x and 0.9984 respectively (Figure 1.). To determine the concentration of glucose in the blood plasma
