How often should I test my cholesterol?
According to the American Heart Association, "Knowing your total blood cholesterol is an important first step in determining your risk for heart disease. Therefore, adults, 20 and over, should have their blood cholesterol (also called total cholesterol) checked at least every 3-5 years. An important second step is knowing your HDL or "good" cholesterol." (In certain cases, it may be necessary to check HDL cholesterol because it is a better predictor of heart disease.)
How often you have a Total Cholesterol Panel (lipid profile) performed will depend on certain factors (such as, cholesterol-lowering drugs and/or other medications, your heart history, and previous cholesterol readings). An initial reading from a Total Cholesterol Panel is good for anyone to use as a starting point to compare against future test results. This is one of the best ways to continually monitor overall cholesterol and heart health.

What is the difference between "normal" levels and "high-risk" levels in cholesterol testing?
There is a considerable overlap in what is considered normal and high-risk. "Normal" levels were derived from a group of patients who had no obvious evidence of coronary heart disease (CHD). However, these findings may not be accurate since these patients may have had preclinical CHD and may not truly reflect a "no-risk" population.
Because of these significant variables, a patient should always consult with his or her primary health care professional.

Why is your LDL cholesterol value a "calculated" LDL?
In the Biosafe test LDL cholesterol is calculated using the Friedwald formula. In this formula, LDL is calculated by subtracting the HDL value and then adding one fifth of the triglycerides from the total cholesterol. The formula looks like this: LDL = Total cholesterol - (HDL + Tryglycerides/5).
Note: The LDL value cannont be accurately calculated if the trigliceride level is greater than 400.

I notice that all your cholesterol test results are given in mg/dL. What does mg/dL mean?
"mg/dL" stands for milligrams per decilier and is the standard unit of clinical measurement used to determine how much cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides are in the blood.

What condition(s) can cause, or be associated with, decreased LDL cholesterol levels?
Conditions that can cause decreased LDL cholesterol levels include, but are not limited to:
Family history of low LDL cholesterolHyperthyroidismHypoproteinemia (malnutrition)
The foods you eat for up to 2 weeks before testing will affect test results.

What condition(s) can cause, or be associated with, increased LDL cholesterol levels?
Conditions that can cause increased LDL cholesterol levels include, but are not limited to:
Family history of increased LDL cholesterolNephrosis (abnormal kidney disorderHypothyroidismAlcohol consumptionChronic liver disease (hepatitis or cirrhosis)Liver cancerCushing's Syndrom
The foods you eat for up to 2 weeks before testing will affect test results.

What condition(s) can cause, or be associated with, decreased HDL cholesterol levels?
Conditions that can cause decreased HDL cholesterol levels include, but are not limited to:
Family history of low HDLSmokingDrinking alcoholHepatocellular disease (hepatitis or cirrhosis)Hypoproteinemia (nephrosis or malnutrition)
HDL values, like total cholesterol values, tend to significantly decrease for as long as 3 months following a heart attack. HDL also decreases in hyperthyroid patients.

What condition(s) can cause, or be associated with, elevated HDL cholesterol levels?
Conditions that can cause elevated HDL cholesterol levels include, but are not limited to:
HypothyroidismFamily history of high HDL cholesterolExcessive exercise

What condition(s) can cause, or be associated with, increased triglyceride levels?
Conditions that can cause increased triglyceride levels include, but are not limited to:
Family history of elevated triglyceride levelsEating fatty mealsDrinking alcoholPregnancyHypothyroidismHigh-carbohydrate dietPoorly controlled diabetesNephrosis (abnormal kidney disorder)High blood pressure
The foods you eat for up to 2 weeks before testing will affect test results.

What condition(s) can cause, or be associated with, low Total Cholesterol levels?
Because the liver is required to make cholesterol, low serum cholesterol levels are indicative of severe liver disease.
Also, since our main source of cholesterol is in the food we eat, low cholesterol levels are associated with malnutrition.
Certain illnesses can also affect cholesterol levels. For example, patients who have suffered a heart attack (acute myocardial infarction) may experience as much as a 50% reduction in cholesterol levels for as many as 6 to 8 weeks after the attack.
Additional conditions include but are not limited to:HyperthyroidismCholesterol-lowering medicationsCertain types of anemiaStress

What condition(s) can cause, or be associated with, high Total Cholesterol levels?
Family history is most often associated with high cholesterol. Pregnancy can also elevate cholesterol levels, as can the surgical removal of one or both ovaries.
Additional conditions include, but are not limited to:Uncontrolled diabetes mellitusHypothyroidismNephrosis (abnormal kidney disorder)High blood pressureStress
