The HDL Cholesterol Test is used to measure the levels of "good" cholesterol in the blood. HDL cholesterol is important because it helps remove harmful cholesterol (LDL) from the arteries, reducing the risk of heart disease and strokes. This test is usually performed as part of a comprehensive blood lipid profile and is recommended for individuals who have risk factors such as a family history of heart disease, obesity, or high blood pressure. HDL cholesterol levels higher than 60 mg/dL are considered a good indicator of heart health, while levels below 40 mg/dL for men and 50 mg/dL for women are considered an indicator of increased risk for heart disease.
