A total cholesterol test is used to screen for the risk of developing heart disease. Because high blood cholesterol has been associated with the hardening of arteries, called atherosclerosis, and an increased risk of death from heart attacks, cholesterol testing is considered a routine part of preventative healthcare.
What is cholesterol?
Cholesterol is a fatty substance that naturally occurs in human blood and is essential for life. It is created in the liver and comes from the foods you eat. Cholesterol forms the membranes for cells in all organs and tissues in the body. It is used to make hormones that are essential for development, growth, and reproduction, and it forms bile acids that are needed to absorb nutrients from food.
How often should I have my cholesterol checked?
Adults should be tested at least once every five years, or more frequently if being treated for high cholesterol or have one or more risk factors for heart disease. Children, teens, and young adults should be tested once between the ages of 9 and 11 and then again between the ages of 17 and 21.
Will this test tell me about my good (HDL) and bad (LDL) cholesterol levels?
The total cholesterol test will only provide you with the total amount of cholesterol in your blood. If you would prefer a breakdown of your cholesterol levels, you will need to have a cardiac screen, also known as a lipid panel, performed.
HOW DO I GET TESTED?
To order your own lab tests, you just need to follow these three easy steps:
- Complete a lab order form for your test online and print it out to take with you to the DLO Patient Service Center. Follow the instructions on the laboratory test order form if fasting is required for the testing you are ordering.
- Visit any DLO Patient Service Center throughout Oklahoma. Check in with our friendly staff and give them your completed order form. Full payment is due at time of service before sample collection is performed. Note that we accept all major credit cards and checks. Unfortunately, we cannot accept cash payments. Have one of our skilled phlebotomists draw a blood sample or take a urine sample, who will send your sample to our laboratory for testing.
- Create a MyQuest™ account and view your test results through the MyQuest online patient portal. Test results are available through MyQuest within 7-10 business days of completing your lab work.
WHAT SHOULD I DO IF MY RESULTS ARE ABNORMAL OR OUT-OF-RANGE?
It is always recommended you meet with a healthcare provider to determine what your laboratory test results mean to you. Your healthcare provider will review all of your test results and, combined with your health history, will be able to provide an accurate picture of your health status.
If your results were within normal range: If your cholesterol is in the desirable range, below 200 mg/dl for adults, you should follow the screening guidelines for your age and health status.
If your results were in the borderline high range: A total cholesterol between 200 and 239 mg/dl is considered to be a moderate risk for heart disease. Your healthcare provider may order a lipid panel to determine your bad and good cholesterol levels. Your healthcare provider may also suggest lifestyle changes, such as improved diet and exercise habits.
If your results were in the high risk range: Cholesterol levels greater than or equal to 240 mg/dl is considered high risk. Your healthcare provider may order a lipid panel to try to determine the cause of the high cholesterol. Once a cause has been determined, appropriate treatment, which may include medication, will be prescribed.
