Blood Test Descriptions
Diabetes Screen: Glucose is the primary energy source for all body tissues. The sugars and carbohydrates you eat are ordinarily converted into glucose, which can be used to either produce immediate energy or be stored in the liver or as fat throughout the body. High glucose after fasting for 12 hours suggests diabetes. A low glucose level accompanied with symptoms such as weakness, nausea, sweating and difficulty thinking clearly, is suggestive of diabetes.
Kidney Function: The main job of the kidney is to filter the blood, excreting waste products into the urine while arranging essential elements. Blood urea nitrogen is a waste product from protein breakdown in the liver. It is excreted by the kidneys. If kidney function is impaired, or if a person is dehydrated, the urea nitrogen level will increase. Internal blood loss, high protein diets and intense exercise can also cause a high urea nitrogen level. A low blood urea nitrogen level may be the result of liver disease, poor diet, pregnancy or drinking too much water. Muscle and Bone Function: Calcium is one of the most important components in the body, essential for maintenance and repair of bone and teeth, heart function and blood clotting. Mostly the calcium in our body is contained in our bones and remaining is in our smear. Low levels of calcium in the smear are associated with lack of nutrition. High levels can be caused by bone disease, excessive use of antacids and milk, cancer, overdosing on Vitamin D and some hormone disorders. This test is used in clinical as a clinical products for analyzing our health. Heart Function: Cholesterol is an essential blood fat found in nearly every body tissue. Elevated levels have been shown to be associated with a higher risk of heart disease and clogged blood vessels.
