The Cardio IQ™ Direct LDL test contains 1 test with 1 biomarker.
Brief Description: The Cardio IQ Direct LDL test is a specialized blood test that measures the concentration of low-density lipoprotein cholesterol (LDL-C) directly in the blood. LDL-C is a type of cholesterol often referred to as "bad cholesterol" because it is associated with the buildup of fatty plaques in the arteries, increasing the risk of cardiovascular diseases.
Also Known As: Direct LDL-C Test, Direct LDL Cholesterol Test, DLDL Test, LDL D Test
Collection Method: Blood Draw
Specimen Type: Serum
Test Preparation: If an LDL-cholesterol measurement is to be performed along with triglycerides, the patient should be fasting 9-12 hours prior to collection
When is a Direct LDL test ordered?
A Cardio IQ Direct LDL test may be ordered when there is a need for accurate and precise measurement of LDL-C levels. This test is particularly useful in the following situations:
Cardiovascular Risk Assessment: The test is ordered as part of a comprehensive cardiovascular risk assessment for individuals with risk factors such as high blood pressure, obesity, diabetes, family history of heart disease, or those who have experienced cardiovascular events in the past.
Monitoring Cholesterol Levels: For patients with known dyslipidemia or a history of high cholesterol, the test helps monitor the effectiveness of lifestyle modifications or medication therapy in reducing LDL-C levels.
Baseline Evaluation: It may be ordered as a baseline evaluation to assess an individual's cholesterol profile before starting lipid-lowering medications.
What does a Direct LDL blood test check for?
The direct low-density lipoprotein cholesterol test determines the amount of LDL cholesterol in the blood, also known as "bad" cholesterol. LDL-C levels beyond a certain threshold are linked to an increased risk of artery hardening and heart disease. The amount of LDL-C is usually determined using readings from a typical lipid profile. This is a good estimate of LDL-C in most circumstances, although it becomes less accurate as triglyceride levels rise. When triglycerides are high, direct measurement of LDL-C is less impacted by them and can be employed.
Lab tests often ordered with a Direct LDL test:
- LDL Cholesterol
- Lipid Panel
- Total Cholesterol
- HDL Cholesterol
- Apolipoprotein B
- Apolipoprotein A1
- Lipoprotein Fractionation Ion Mobility
Conditions where a Direct LDL test is recommended:
The Cardio IQ Direct LDL test is particularly useful in individuals with:
Hypercholesterolemia: High levels of LDL-C, which increases the risk of atherosclerosis and cardiovascular diseases.
Atherosclerosis and Cardiovascular Disease: To assess the progression of atherosclerosis and risk of heart attacks or strokes.
How does my health care provider use a Direct LDL test?
Low density lipoprotein cholesterol levels are commonly used to determine a person's risk of heart disease or to monitor their response to cholesterol-lowering medication. Total cholesterol, high-density lipoprotein cholesterol, and triglycerides are all assessed in a conventional lipid profile. The amount of cholesterol present in low-density lipoprotein can be calculated using a mathematical calculation based on the three observed values. The calculated LDL-C value is often included in the lipid profile. The calculation is no longer applicable when triglycerides are high. The only way to precisely determine LDL-C in this case is to measure it directly.
A metabolic disease affecting lipids could cause high triglycerides. After eating, though, anyone can have high triglycerides. The direct LDL-C test can identify the amount of LDL in a person's blood in either condition.
What do my Direct LDL test results mean?
Increased LDL levels, as determined by the direct LDL-C test, suggest a higher risk of heart disease. Reduced levels imply a reduction in the risk of heart disease as a result of lipid-lowering lifestyle adjustments and/or pharmacological therapy.
Low LDL levels are usually not a cause for worry and are not monitored. They can appear in persons who have a hereditary lipoprotein insufficiency, as well as in people who have hyperthyroidism, infection, or inflammation.
