What is LDL Cholesterol Blood Test?
LDL tests are a type of blood test used by doctors to determine how much LDL cholesterol is present in a person’s circulation. LDL testing can be part of a lipid panel test or can be used to determine LDL levels on their own.
Cholesterol cannot be dissolved in the blood. It must be transported to and from cells through molecules called lipoproteins. On the one hand, low-density lipoprotein (LDL) is also known as “bad” cholesterol. One molecule of bad cholesterol (LDL) is a single molecule of apolipoprotein that helps circulate fatty acids, and the only function of these less dense molecules is to transport cholesterol to tissues and arteries.
Why get a Blood LDL Cholesterol test?
In most cases, a person with high cholesterol levels will show no signs or symptoms. High amounts of LDL cholesterol, on the other hand, can cause plaque to build up in a person’s blood vessels.
Plaque is made up of fat, cholesterol, calcium, and waste products from the body’s cells. Plaque can accumulate inside a person’s arteries, narrowing or blocking them. Plaque accumulation can lead to:
- Coronary artery disease (CAD).
- Stroke and heart attack.
- Chronic kidney disease is a condition that affects the kidneys.
As a result, it is critical that a person’s cholesterol levels be monitored on a frequent basis. A person may need to fast for 9–12 hours before getting an LDL blood test.
What does the test measure?
The higher the level of bad cholesterol in the blood, the higher the risk of developing coronary heart disease.
High LDL cholesterol levels may be caused by:
- Kidney disease.
- Liver disease.
- Sub active thyroid gland (hypothyroidism).
Low LDL cholesterol levels are not considered dangerous. They can be found in patients with inherited lipoprotein deficiency, in those with:
- Inflammation and cirrhosis.
How long do blood test results take?
The target turnaround time for LDL Cholesterol Blood test is 1-2 working days from receiving in the laboratory.
