Lipoprotein (A) Test
Your doctor will order Lipoprotein (a) Test to check for risk of stroke, heart attack or other heart-related conditions only if you have certain risk factors, such as a family history of heart disease. This test estimates the level of lipoprotein (a) in the blood. Lipoproteins are composed of protein and fat that carry cholesterol through the bloodstream.
How does Lipoprotein (A) Test Help?
Lipoprotein (A) test helps in determining the levels of a specific type of low-density lipid present in the bloodstream. It is directly responsible for maintaining a healthy cardiovascular system.
It is often performed for patients who have a history of cardiovascular distress. In patients with cardiac complaints, it is not the first line of diagnosis. Levels of triglycerides, cholesterol and other lipoproteins are usually checked first.
ECG or angiography may also be required in such patients. If these diagnostic tests still leave a doubt in the physician’s mind, Lipoprotein (A) test levels are checked.
Importance of Lipoprotein (A) Test
- Lipoprotein A is chemically composed of a core of fat and cholesterol, which is surrounded by a rim of proteins. This lipoprotein circulates through a complex network of blood vessels and may get deposited on the insides of vascular walls. If this happens recurrently, the fat deposits increase, leading to a narrowed vascular lumen.
- If the coronary arteries get blocked because of lipoprotein (A) deposit, it could lead to reduced blood supply to the heart muscles. That may cause myocardial ischemia and other similar cardiac disorders.
- A venous blood sample is required to measure blood levels of Lipoprotein (A). A vein in the patient’s upper arm is chosen to withdraw the blood sample. The sample is preserved by mixing it with anticoagulants until it is tested. Advanced medical technology and highly calibrated tools are used to perform the tests and get accurate results.
- Levels of Lipoprotein A in a healthy person are usually lesser than 30mg/dL. Levels above 30 are harmful and a probable risk for developing cardiovascular disorders.
- Other disorders which disturb the levels of Lipoprotein A include severe hypothyroidism, abnormally elevated blood sugar levels, disturbed levels of estrogen, etc.
- Lipoprotein (A) test should be performed only if it has been prescribed by a physician or cardiologist.
