LDL Cholesterol
Lipids & Cardiovascular
Atherogenic 'bad' cholesterol. Lower is generally better.

Low-density lipoprotein (LDL) cholesterol is a lipoprotein containing Apolipoprotein B that carries cholesterol through the blood. When LDL levels are too high, cholesterol-laden particles can become trapped in artery walls, driving atherosclerosis and increasing the risk of heart attack and stroke. Wellth offers LDL cholesterol testing through accredited Swedish laboratories, typically as part of a comprehensive lipid panel that provides a complete view of your cardiovascular risk.
LDL cholesterol testing is fundamental for evaluating and managing cardiovascular risk. Both genetic studies and large clinical trials consistently show that lower LDL particle concentrations reduce heart disease risk. Testing is recommended for routine health screening, for people with a family history of cardiovascular disease, and for monitoring the effectiveness of dietary changes, lifestyle modifications, or lipid-lowering medications.
What a high value can mean
High LDL cholesterol means there are more atherogenic particles available to become trapped in artery walls, accelerating plaque formation and increasing the risk of heart attack and stroke. Causes include genetic factors such as familial hypercholesterolaemia, a diet high in saturated fats and trans fats, low fibre intake, smoking, hypothyroidism, and insulin resistance. The more Apolipoprotein B-containing particles circulating in your blood, the higher your cardiovascular risk.
What a low value can mean
Low LDL cholesterol is generally associated with lower cardiovascular risk. However, very low levels may indicate oxidative stress, malnutrition, hyperthyroidism, autoimmune conditions, or liver dysfunction. In pregnancy, low LDL may increase the risk of premature birth. If your LDL is significantly below normal, your doctor may investigate underlying causes.
Do not eat or drink anything except water for at least 10 hours (preferably 12) before the test. Postpone the test if you are ill and wait at least 6 weeks after illness. This test is best done in the early morning after an overnight fast. Bring valid identification.

Your values appear in your account with reference ranges and an explanation of each marker.
For most adults, an LDL below 3.0 mmol/L is considered desirable. For those at high cardiovascular risk, a target below 1.8 mmol/L is often recommended. Your lab results will include the specific reference range.
LDL particles can become trapped in artery walls and trigger plaque formation (atherosclerosis). Higher numbers of circulating LDL particles mean greater risk. However, cholesterol itself is essential for health -- it is the excess LDL particles that drive disease.
Reducing saturated and trans fat intake, increasing dietary fibre, regular exercise, weight management, and quitting smoking all help lower LDL. When lifestyle changes are not enough, statin medications are highly effective.
Yes. Fasting for at least 10 to 12 hours is recommended for accurate LDL measurement, as food intake can significantly affect lipid levels. Drink only water during the fasting period.
