clinical definition of lp (a) â€“ lipoprotein(a)
Lipoprotein (a) commonly known as Lp (a) are molecules made of proteins and fat. They carry cholesterol and similar substances through the blood. They are made in the liver and are genetic variation of LDL (bad) cholesterol. They are very similar to LDL, or “bad” cholesterol, except that the LDL cholesterol molecule has an apolipoprotein (A) molecule attached to it. Lp (a) may interact with substances found in the artery walls and contribute to the buildup of fatty deposits. It has been identified through some research studies, as a risk factor for atherosclerotic diseases such as coronary heart disease (CHD), cerebrovascular disease (CVD), thrombosis, and stroke. However, the complete function of lipoprotein (a) is not fully known although it has been found that it is is genetically linked.
when do you expect results?
24 to 36 Hours
why get tested?
A Lp(a) is ordered to when a person is found vulnerable and at the risk of developing heart disease. The test also monitors on going treatment for cardio vascular diseases. The Lp(a) detects the the lipoprotein component present in the blood. It is also conducted to rule out other risks like atherosclerosis, stroke, and heart attack.
reason to take lp (a) â€“ lipoprotein(a) test
Symptoms to watch out for are pain, fullness, and/or squeezing sensation of the chest, jaw pain, toothache, headache, nausea, vomiting, and/or general epigastric (upper middle abdomen) discomfort, sweating, heartburn and/or indigestion.
Arm pain (more commonly the left arm, but may be either arm)
Upper back pain, hypertension, shortness of breath and general malaise.
preparations needed for lp (a) â€“ lipoprotein(a) test
Fasting samples have to be collected after a minimum 12-14 hour overnight fasting status.
Clear fluids like water is allowed during this period. Refrain from consumption of early morning beverages like tea, coffee and milk until specimen collection is completed.
In case of diabetics on oral or injectable hypoglycemic agents, consult your physician about continuing with these medications prior to specimen collection.
Specimen type: Serum (Blood Sample),Specimen collection procedure:Venipuncture (Collection of blood from a vein, usually from the arm)
Understanding results ofLp (a) â€“ Lipoprotein(a)
|< 14 mg/dL||Desirable|
|31 - 50 mg/dL||High risk:|
|14 - 30 mg/dL||Borderline risk|
|> 50 mg/dL||Very high risk|
‘*A Reference range is a set of values which helps the healthcare professional to interpret a medical test. It may vary with age, gender, and other factors. Reference ranges may also vary between labs, in value & units depending on instruments used and method of establishment of reference ranges’
