Heart disease is the number one killer in the U.S. and a major cause of disability. Your blood offers many clues about your heart health. For example, high levels of "bad" cholesterol in your blood can be a sign that you're at increased risk of having a heart attack. And other substances in your blood can help determine if you are at risk of developing plaque deposits in your arteries called atherosclerosis.
If you do have a heart disease, it is important to find it early when it is easier to treat. Heart Health tests can help find heart diseases or identify problems that can lead to heart diseases. Additionally they can detect substances that normally are not present or measure substances that, when elevated above normal levels, may indicate disease.
