Total is a combination of direct and indirect bilirubin. Typically, you'll get results for direct and total bilirubin. Normal results for a bilirubin test are 1.2 milligrams per deciliter (mg/dL) of total bilirubin for adults, and usually 1 mg/dL for those under 18. Normal results for direct bilirubin are generally 0.3 mg/dL. These results may vary slightly from laboratory to laboratory. Normal results may be slightly different for women and children, and results may be affected by certain foods, medications or strenuous exercise.
What Are the Signs and Symptoms of Atherosclerosis? Atherosclerosis usually doesn't cause signs and symptoms until it severely narrows or totally blocks an artery. Many people don't know they have the disease until they have a medical emergency, such as a heart attack or stroke.
When atherosclerosis affects the arteries of the heart, it is called coronary heart disease. The buildup of plaque inside the coronary arteries limits the flow of blood to the heart muscle. A common symptom of coronary heart disease is chest pain or discomfort, especially with exertion. Coronary atherosclerosis may advance to the point that blood supply to an area of the heart becomes so limited, or even completely blocked, that muscle damage occurs in the form of a heart attack.
