The Cardio IQ™ Direct LDL test contains 1 test with 1 biomarker.
Description: Direct LDL is a blood test that measures LDL cholesterol in your blood’s serum to determine risk of heart disease.
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?
When calculating LDL cholesterol is impossible due to a considerable increase in triglycerides, a direct LDL-C test is ordered. A doctor may order it if previous tests have revealed elevated triglyceride levels. When triglyceride levels are too high to calculate LDL-C, certain laboratories will automatically do this direct LDL test. This saves the doctor time by avoiding the need to order another test, the patient time by avoiding the need for a second blood sample, and the time it takes to get the test results.
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:
- Heart Disease
- Coronary Artery Diseases
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.
We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.
