How to Measure Cholesterol Levels

Labs may diagnose high cholesterol with more accuracy than an at-home test.

A blood test is the only way to get an accurate reading on your cholesterol levels. While home testing devices can be more convenient than a trip to the doctor, measuring cholesterol at home does not necessarily give you an accurate reading or enough information. The American Heart Association hasn't taken a position on home testing devices, but the Harvard Medical School Family Health Guide recommends getting a cholesterol check from a professional. A doctor can also provide treatment if the test proves that you have an unhealthy level of cholesterol.

Instructions

1. Schedule an appointment with a doctor.

2. Order a blood test to check your cholesterol levels. Tests check total cholesterol, high-density lipoprotein, also known as HDL or good cholesterol, as well as low-density lipoprotein, also known as LDL or bad cholesterol, and triglycerides, referred to as blood fats.

3. Schedule the test to allow yourself plenty of time to fast. You need to fast for nine to 12 hours before you take the blood test. During this time, you cannot have food, liquids or pills.

4. Take the blood test at the facility. Lab results take one to two weeks depending on the facility. Call your doctor to check on the results if you do not hear anything within seven days. If your total cholesterol or triglycerides are high, then your doctor will recommend a lipid panel test. Other tests also might be ordered depending on your family history, such as a test to determine risk for cardiovascular disease.
