Blood Tests Explained



Testing your Glucose Levels

About our Company: Blood glucose is a measurement of sugar in your blood stream. It is a normal constituent of the blood and essential for cellular metabolism. With diabetes your blood sugar is elevated and can lead to complications such as eye disease, nerve damage, atherosclerosis and other problems. Direct costs of treating diabetes every year is $44 billion and indirect costs $98 billion. Blood glucose monitoring is the cornerstone of good diabetes control. Glucose is tested by diabetics as many as 6 or more times a day.

Why should you check your Total Cholesterol?

Cholesterol is the main lipid associated with artheriosclerotic vascular disease. It is required for cellular membranes. Cholesterol testing is to identify patients at risk for arteriosclerotic heart disease. Total cholesterol is made up of LDL, HDL and triglycerides and VLDL. Diabetics are prone to higher levels of blood fats in their systems – which puts them at increased risk of heart and blood vessel disease. Total cholesterol should be below 200. Eighty percent of diabetics die from heart and blood vessel complications. It has been shown that a 1 percent decrease in cholesterol levels lead to a 2 percent decrease in the risk of heart disease. Each year coronary heart disease kills more Americans than any other cause. More than 13 million Americans have heart disease.

HDL, the Good Cholesterol

HDL is a protein in the blood whose main purpose is to transport cholesterol, triglycerides and other insoluble fasts to the liver for excretion from the body. HDL should be above 35 mg/dL. By dividing your total cholesterol by your HDL cholesterol you can get a ratio indicating your risk of heart disease, a ratio below 3.5 is desirable.

What are Triglycerides?


Triglycerides are a form of fat in the bloodstream. They act as a storage source for energy. Elevated triglycerides are now thought to be an independent risk factor for heart disease. People with diabetes are prone to elevated triglyceride levels. Fasting triglycerides should be below 200 mg/dL.

Blood Ketones (b-hydroxybutyrate)

Under normal conditions, no ketones are present in the urine; however, a patient with poorly controlled diabetes and elevated blood sugar may have fat catabolism and ketones are a bi-product of fat metabolism. Diabetics need to monitor their ketone levels when their blood sugar is elevated, when they are sick and in times of stress. In addition patients on high-protein (Atkin’s) diets may want to monitor their ketone levels to verify they are in ketosis, burning fat and therefore losing weight.

What is Creatinine?


Creatinine is a product of creatinine phosphate, which is used in skeletal muscle contraction. Daily production depends on muscle mass. Creatinine is excreated entirely by the kidneys and therefore directly proportional to renal excretory function. Elevation occurs later in disease process and suggests chronic disease rather than acute. Measuring serum creatinine is useful in evaluating any type of renal dysfunction or changes in disease progression.
