Blood sugar levels in diagnosing diabetes Plasma glucose test Normal Prediabetes Diabetes Random Below 11.1 mmol/l Below 200 mg/dl N/A 11.1 mmol/l or more 200 mg/dl or more Fasting Below 5.5 mmol/l Below 100 mg/dl 5.5 to 6.9 mmol/l 100 to 125 mg/dl 7.0 mmol/l or more 126 mg/dl or more 2 hour post-prandial Below 7.8 mmol/l
Result Fasting Plasma Glucose (FPG) Normal less than 100 mg/dl Prediabetes 100 mg/dl to 125 mg/dl Diabetes 126 mg/dl or higher Oral Glucose Tolerance Test (also called the OGTT) - The OGTT is a two-hour test that checks your blood glucose levels before and 2 hours after you drink a special sweet drink. It tells the doctor how your body processes glucose.
Mar 31, 2018 · The normal fasting plasma glucose level was recently defined as less than 100 mg per deciliter (5.55 mmol per liter). Whether higher fasting plasma glucose levels within this range independently predict type 2 diabetes in young adults is unclear.
Hyperglycemia is a defining characteristic of diabetes—when the blood glucose level is too high because the body isn't properly using or doesn't make the hormone insulin. You get glucose from the foods you eat.
Tweet A fasting plasma glucose test, also known as a fasting glucose test (FGT), is a test that can be used to help diagnose diabetes or pre-diabetes. The test is a simple blood test taken after several hours of fasting. How a fasting glucose test is performed A fasting glucose test will be performed in the morning as this provides the body with adequate time to fast. The NHS advises people who are having a fasting glucose test not to eat or drink anything except water for 8 to 10 hours before the test is performed. The test requires a blood sample to be taken from the patients arm. Fasting glucose test results The World Health Organisations defines the following fasting glucose test results: Normal: Below 6.1 mmol/l (110 mg/dl) Impaired fasting glucose: Between 6.1 and 6.9 mmol/l (between 111 mg/dl and 125 mg/dl) Diabetic: 7.0 mmol/l and above (126 mg/dl and above) Impaired fasting glucose is a form of pre-diabetes. Read more on impaired fasting glucose. Tweet Type 2 diabetes mellitus is a metabolic disorder that results in hyperglycemia (high blood glucose levels) due to the body: Being ineffective at using the insulin it has produced; also known as insulin resistance and/or Being unable to produce enough insulin Type 2 diabetes is characterised by the body being unable to metabolise glucose (a simple sugar). This leads to high levels of blood glucose which over time may damage the organs of the body. From this, it can be understood that for someone with diabetes something that is food for ordinary people can become a sort of metabolic poison. This is why people with diabetes are advised to avoid sources of dietary sugar. The good news is for very many people with type 2 diabetes this is all they have to do to stay well. If you can keep your blood sugar lower by avoid Continue reading >>
Also known as: RPG; casual plasma glucose test; random blood sugar test. What is it? The random plasma glucose test measures plasma (or blood) glucose levels. It is performed with a small blood draw taken at any time of the day (hence the term “random”). Why is this test performed? Generally, as a screening test for diabetes when a patient has serious diabetes symptoms and has had food or drink, and therefore can’t do a fasting plasma glucose test or oral glucose tolerance test. How is this test performed? The test consists of a simple blood draw, which is sent to your doctor’s lab for analysis. What do normal results mean? A random plasma glucose test that is under 200 mg/dl (11.1 mmol/l) is considered acceptable. What do abnormal results mean? Levels of 200 mg/dl (11.1 mmol/l) or higher, along with the presence of symptoms of diabetes (e.g., excessive thirst and/or urination, blurry vision, unexplained weight loss), indicate a diagnosis of diabetes. The results should be confirmed through a separate test, either the oral glucose tolerance test or the fasting plasma glucose test, taken on another day. Other conditions which may result in an elevated result include pancreatitis, Cushing’s syndrome, liver or kidney disease, eclampsia, and other acute illnesses, such as sepsis and myocardial infarction (heart attack).

Too little glucose, called hypoglycemia, starves cells, and too much glucose ( hyperglycemia) creates a sticky, paralyzing effect on cells. Euglycemia, or blood sugar within the normal range, is naturally ideal for the body’s functions.
Glucose from the bloodstream enters liver cells, stimulating the action of several enzymes that convert the glucose to chains of glycogen—so long as both insulin and glucose remain plentiful. In this postprandial or “fed” state, the liver takes in more glucose from the blood than it releases.
In a healthy liver, up to 10% of its total volume is used for glycogen stores. Skeletal muscle cells store about 1% of glycogen. The liver converts glycogen back to glucose when it is needed for energy and regulates the amount of glucose circulating between meals.
Regulation of Blood Glucose. Regulation of glucose in the body is done autonomically and constantly throughout each minute of the day. Normal BG levels should be between 60 and 140 mg/dL in order to supply cells of the body with its required energy. Brain cells don’t require insulin ...
Of the three fuels for the body, glucose is preferred because it produces both energy and water through the Krebs cycle and aerobic metabolism.
Regulation of blood glucose is largely done through the endocrine hormones of the pancreas, a beautiful balance of hormones achieved through a negative feedback loop. The main hormones of the pancreas that affect blood glucose include insulin, glucagon, somatostatin, and amylin.
People with diabetes have frequent and persistent hyperglycemia, which is the hallmark sign of diabetes. For people with type 1 diabetes, who make no insulin, glucose remains in the blood plasma without the needed BG-lowering effect of insulin. Another contributor to this chronic hyperglycemia is the liver.
