    How to diagnose High Blood Cholesterol ?
    ### Response:
    Your doctor will diagnose high blood cholesterol by checking the cholesterol levels in your blood. A blood test called a lipoprotein panel can measure your cholesterol levels. Before the test, youll need to fast (not eat or drink anything but water) for 9 to 12 hours.
