The Fasting Cholesterol Test
Individuals who might be at risk for high cholesterol will need to have blood tests done in order to determine how high the cholesterol really is. Depending upon the results of those tests, a physician might prescribe a diet, or even medication to help lower cholesterol. Many people who are scheduled to come in for lab work are told to fast, or not anything from a certain point before the scheduled test. Below, we’ll discuss fasting, cholesterol and testing.
Simple Cholesterol Tests
For a simple cholesterol test, you probably won’t be asked to fast. The reason is because the test measures just the total cholesterol levels and HDL or high-density lipoprotein, which is often called ‘good cholesterol’ because it helps lower LDL or low-density lipoprotein – which is considered bad cholesterol. The simple cholesterol test can give physicians a good idea of how high your cholesterol is and how healthy you are.
For the fasting cholesterol test, you will not be allowed to eat for several hours before your blood is taken. It is a very complete test and measures LDL and HDL cholesterol as well as triglycerides. This gives doctors a complete view of how high your cholesterol really is and how damaging it could be to your health. If you’ve eaten recently, it could affect the results of the test so that your doctor doesn’t get an accurate reading. This is dangerous, as you could be placed on medication that you don’t actually need.
The cholesterol tests enable doctors to make educated decisions about your health. Although it’s annoying to have to fast in order to receive the tests, it really is an investment in your health and should be taken seriously. Your body will thank you later.
