Apolipoprotein - B

Apolipoprotein B, known as Apo-B, is a critical protein involved in the transport and metabolism of fats in the blood. It is primarily associated with low-density lipoprotein (LDL), also known as “bad” cholesterol. Elevated levels of Apo-B are associated with an increased risk of atherosclerosis, the process involving the buildup of plaque (harmful fats, cholesterol, and other substances) in the arteries (blood vessels that carry blood). This buildup can lead to heart attacks, strokes, and other cardiovascular diseases. Therefore, understanding your Apo-B levels can be an important part of managing your overall heart health.

An Apolipoprotein - B is especially useful when standard cholesterol tests, such as LDL cholesterol levels, may not provide a complete picture of cardiovascular risk. Your doctor may advise this test if you experience symptoms suggestive of heart disease or cardiovascular problems, such as chest pain, shortness of breath, palpitations, or other cardiac symptoms. Apolipoprotein - B test is also recommended if you have risk factors such as high blood pressure, high cholesterol, obesity, diabetes, smoking, or a family history of heart disease or chronic conditions like diabetes, high blood pressure, etc. This test is also recommended to monitor the effectiveness of ongoing treatment in individuals already diagnosed with cardiovascular disease. Additionally, an Apolipoprotein - B also helps diagnose a rare inherited deficiency of Apolipoprotein B. 

No fasting is required for this test. You can eat and drink normally as per your routine. It is important to inform your doctor about any heart medications or supplements you are taking, as some could impact the test results. Always seek your doctor’s advice before altering any medication routine. 

Lab test results may vary across different laboratories. Discuss your symptoms and specific test results with your doctor to help them correlate your clinical and laboratory findings. Based on your test results, the doctor may recommend a treatment plan and lifestyle adjustments. These can include dietary changes, weight loss, medication, and discontinuation of certain medications.
