Lipoprotein (a), Lp(a)
The Lp(a) test is used to measure the blood level of small dense lipoproteins, which are a direct link to the formation of arterial plaques (atherosclerosis), and is a strong indicator for coronary heart disease.
Elevated blood levels of lipoprotein are associated with increased risk of cardiac death in individuals with a history of acute heart attacks and coronary bypass procedures. Lp(a) also increases risk for coronary heart disease and ischemic stroke. An 8 to 12 hour fast is required for this blood test. However, drink plenty of water and take medications as prescribed.
Special Note: Intake of alcohol, aspirin, niacin, and estrogen supplements have the potential of causing a misrepresentation of true Lp(a) concentrations.
