There is very little risk for having your blood drawn. However, veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaning a blood sample from some people may be more difficult than from others.

• Excessive bleeding
• Fainting or feeling light-headed
• Hematoma (blood accumulating under the skin)
• Infection (a slight risk any time the skin is broken)
• Multiple punctures to locate veins

Conditions under which the test may be performed:

• Acute MI
• Atheroembolic renal disease
• Familial hyperlipidemia
• Familial hypertriglyceridemia
• Familial hypercholesterolemia
• Hyperlipidemia
• Ischemic cardiomyopathy
• Stroke secondary to atherosclerosis
• Transient ischemic attack (TIA)
