Blood test - cholesterol

A complete cholesterol test — also called a lipid panel or lipid profile — is a blood test that can measure the amount of cholesterol and triglycerides in your blood. Knowing your cholesterol levels is an essential part of understanding your own risk for heart disease. High cholesterol levels usually don't cause any signs or symptoms, so a cholesterol test is an important tool. The American Heart Association recommends that everyone over age 20 get a cholesterol test. Experts recommend follow-up cholesterol testing every five years for most people. People with abnormal lipid panels, or who have other risk factors, may need more frequent cholesterol exams.

Urine test - what you should know

The urinary system consists of the kidneys, ureters, bladder, and urethra. The kidneys take out waste material, minerals, fluids, and other substances from the blood to be passed in the urine. Urine has hundreds of different body wastes. By examining urine, indications for diseases of the urinary system can be detected. Urine tests are very useful for providing information to assist in the diagnosis, monitoring and treatment of a wide range of diseases. Urine test can also provide evidence of metabolic diseases like diabetes or liver disease. 

Understanding blood test

Blood tests alone can't be used to diagnose many diseases or medical problems. But blood tests can help you and your doctor learn more about your health. Blood tests also can help find potential problems early, when treatments or lifestyle changes may work best.
