LDL CHOLESTEROL

The test that determines the LDL cholesterol levels is a component of the lipid profile. The Lipid profile is a blood test that determines the concentrations of triglycerides, total cholesterol, LDL cholesterol and HDL cholesterol levels in the cholesterol. It is referred to as ‘bad cholesterol’ because an abundance of it can cause severe heart ailments such as coronary artery disease, heart attacks, and strokes. This test is particularly important for determining cardiovascular risk and monitoring treatment plans. 

The procedure is quite straightforward. A qualified nurse or doctor collects a blood specimen from your arm and sends it to a lab for thorough examination. There, the different blood-based components including LDL cholesterol are filtered out from the blood via centrifuges and other special devices. The level of LDL cholesterol is quantitatively determined by means of a special method of enzymatic colorimetry. 

The test quantifies the amount of LDL in milligrams per decilitre. This unit of measurement assists healthcare providers to understand the risk of heart diseases within an individual and the appropriate course of action to take. 

An LDL cholesterol test is performed as a component of a lipid profile that encompasses total cholesterol, triglycerides, HDL, and LDL cholesterol levels. The test may be suggested by a healthcare professional to be undertaken: 

• For adults with no risk factors, every 4-6 years. 
• For adults having the below risk factors annually: 
• Hypertensive 
• Diabetic 
• Cardiac family history 
• Smoker 
• As part of a life insurance medical check-up or pre-employment medicals. 
• For evaluation of the effectiveness of cholesterol-lowering medications. 

There are various risks and limitations to the LDL cholesterol test which you might want to pay attention to: 

• Risks: 
• Infection and/or bruising in the area where the blood was drawn. 
• Feeling faint. 
• Experiencing nausea or vomiting. 
• Limitations: 
• Testing can only quantify LDL cholesterol but no other cardiovascular risk factors. 
• It contains the potential to underestimate certain individuals' cardiovascular risks. For example, individuals with a strong family history of coronary heart disease. 

The myriads of factors like variations in lipid levels and even the test itself can alter the resultant findings. 

The LDL cholesterol test evaluates the following parameters: 

• The LDL cholesterol level in mg/dL? 
• The size of the LDL particle (Presence of small, dense LDL particles is associated with higher cardiovascular risks) 
• The number of LDL particles (Larger numbers are associated with elevated cardiovascular risks) 

Are these relevant factors correct when performing the LDL cholesterol test? Healthcare specialists check all of this and may also include additional questions such as gender, age, family history as well as pre-existing and current medical conditions to judge the overall risk. 

The LDL cholesterol test is recommended for: 

• Adults aged 20-75 years, as part of a routine lipid profile. 
• Individuals with heart disease risks such as high BP, diabetes, or a family history with heart problems. 
• Persons with a personal history of heart diseases and or strokes. 
• Women who are pregnant or planning to become pregnant. 

Healthcare professionals use the healthcare diagnostic parameters gathered from the LDL test to: 

• Determine who has the greatest risk of coronary heart disease. 
• Create specific plans to lower health risks. 
• Ensure that the patients who are helping lower cholesterol effectively do respond to treatment. 
• Suggestions for change sum up day to day diet and exercise. 

The LDL cholesterol test can help diagnose: 

• Hypercholesterolemia 
• Coronary artery disease 
• Cerebrovascular disease 
• Peripheral artery disease (PAD) 

To prepare for the LDL cholesterol test: 

Prerequisites: NONE 

Eligibility All adults between ages 20 to 75, or per a doctor’s recommendation. 

Procedure for Taking the Test:
