Apolipoprotein - B
Understanding Apolipoprotein - B
What is Apolipoprotein - B?
An Apolipoprotein - B test checks the amount of apolipoprotein B (Apo B) in the blood. Apo B is a protein that helps carry cholesterol and fats (triglycerides) through the body. This test is done to check how healthy the heart is. It also helps find out the risk of heart-related problems like heart attack and stroke.
Apolipoprotein B, or Apo - B, is an essential protein that assists in transporting fats within the blood. It is primarily associated with low-density lipoprotein (LDL), or "bad cholesterol." Elevated levels of Apo - B may lead to plaque (fat buildup) in the arteries. This may raise the risk of heart attacks, strokes, and other heart conditions. That is why it is crucial to know the Apo-B level for maintaining heart health.
An Apolipoprotein - B test is useful when routine cholesterol tests are not providing sufficient information regarding heart health. Doctors might order this test if there are symptoms of heart issues, such as chest discomfort, shortness of breath, or rapid heartbeat. It can also be ordered if there are risk factors such as high blood pressure, high cholesterol, obesity, diabetes, or a family history of heart disease. This test also helps assess whether the treatment is effective in individuals with an existing heart condition. It can also be used to diagnose a very rare inherited disorder in which the body does not produce enough Apo B protein.
No fasting is required for this test. Eat and drink normally. Inform the doctor about any medicines or supplements being taken for heart problems, as they may affect test results. Always consult the doctor before making any changes to medication.
Test results can be slightly different depending on the lab. The doctor will explain what the result means. Based on the result, the doctor may plan a treatment or give advice on changes in lifestyle and medicines to manage the condition.
What is Apolipoprotein - B used for?
An Apolipoprotein - B test is done:
- To find out if you are at risk for heart problems.
- If you have health risks like a family history of heart disease, obesity, diabetes, high blood pressure, or have had a heart attack or stroke before.
- If there are symptoms like chest pain, shortness of breath, or a fast heartbeat.
- To check how well current heart treatments are working.
- To monitor how lifestyle changes are helping people with high risk.
What does Apolipoprotein - B measure?
The Apolipoprotein - B test measures the level of Apo B in the blood. The protein helps in transporting fats and cholesterol within the body. Apo B is a central component of some fat-carrying particles in the blood, such as very low-density lipoprotein (VLDL), low-density lipoprotein (LDL), and chylomicrons. It binds to LDL or "bad" cholesterol, which may result in plaque developing in the blood vessels. This accumulation can lead to heart disease, which can become grave or life-threatening if left untreated.
Interpreting Apolipoprotein - B results
Interpretations
Apolipoprotein A1 is the primary protein associated with HDL Cholesterol. It shows a protective function against heart disease. Increased levels are associated with reduced risk of cardiovascular disease.
Apolipoprotein B is the primary protein associated with LDL Cholesterol and plaque formation. Increased levels are associated with increased risk of heart disease.
The ratio of these two correlates with the risk of cardiovascular disease.
