Lp(A) Lipoprotein(A) Serum Test

What is a Lipoprotein(a) Test?

The Lipoprotein(a) Test, also known as the Lp(a) Test, measures the level of Lipoprotein(a) in the blood. Lipoprotein(a) is a type of low-density lipoprotein (LDL) that carries cholesterol and a special protein called apolipoprotein(a).

High levels of Lp(a) are linked to an increased risk of cardiovascular conditions such as coronary artery disease, heart attack, and stroke. Since Lp(a) levels are largely determined by genetics, this test is an important screening tool for individuals with a family history of early heart disease.

What Does the Lipoprotein(a) Test Measure?

This test measures the amount of Lipoprotein(a), a cholesterol-carrying particle that can contribute to plaque buildup in arteries. Elevated levels increase the risk of atherosclerosis, which can restrict blood flow and cause heart or vascular problems.

Your doctor may use this test to:

• Assess inherited risk for heart disease or stroke
• Evaluate unexplained high cholesterol levels
• Identify cardiovascular risk in patients with a strong family history of heart disease
• Guide cholesterol-lowering therapy and preventive care

Who Should Get a Lipoprotein(a) Test and Why It Is Done

When is a Lipoprotein(a) Test Recommended?

You may be advised to take this test if you have:

• A family history of early heart disease (men before 55, women before 65)
• High LDL cholesterol despite treatment
• Unexplained cardiovascular events
• Stroke or heart disease at a young age
• Recurrent heart attacks or blocked arteries

Why Is the Lipoprotein(a) Test Done?

The test helps to:

• Detect genetic risk for cardiovascular disease
• Assess likelihood of developing atherosclerosis
• Monitor lipid-lowering treatment response
• Support early prevention strategies for heart and vascular health

Importance of a Lipoprotein(a) Test

High Lipoprotein(a) levels are a strong genetic risk factor for heart disease and stroke. Unlike other cholesterol types, Lp(a) levels are not significantly affected by diet, exercise, or most lipid-lowering medications.

This makes the test valuable for identifying individuals who may be at risk even when their standard cholesterol results are normal. It supports timely preventive actions such as lifestyle modifications and advanced treatment plans.

Understanding Abnormal Lipoprotein(a) Test Results

Preparation for a Lipoprotein(a) Test

• No fasting is required unless the test is combined with a full lipid profile.
• Inform your doctor about any medications you are taking.
• Stay hydrated and avoid heavy meals immediately before sample collection.
• Provide complete medical and family history for accurate risk evaluation.

How Is a Lipoprotein(a) Test Performed?

• A blood sample is collected from a vein in your arm.
• Around 3 ml of serum is required and stored in a gel vacutainer.
• The sample is analysed using Immunoturbidimetry to measure Lp(a) levels.
• Results are compared with biological reference values.

The process is quick, simple, and minimally invasive.

Factors That May Affect Lipoprotein(a) Test Accuracy

• Genetic inheritance (main determinant)
• Kidney disease or diabetes
• Thyroid or liver disorders
• Hormonal changes (especially post-menopause)
• Incorrect sample storage or handling
