Fragen und Antworten zu Apolipoprotein A
What is the respective laboratory value?
Apolipoprotein A1 (ApoA1) is a major component of HDL cholesterol and plays a central role in the transport of cholesterol to the liver. The laboratory value measures the concentration of ApoA1 in the blood and is used to assess cardiovascular risk.
For whom is such a test to be considered?
An ApoA1 test is recommended for: • Persons with increased risk of cardiovascular diseases • Patients with abnormal lipid profiles (e.g. low HDL cholesterol) • Monitoring of patients with known arteriosclerosis or cardiovascular diseases • Persons with familial lipid metabolism disorders
What is it used for?
The test serves to assess the risk of arteriosclerosis and cardiovascular diseases, as well as to monitor the success of therapy for lipid metabolism disorders.
What can be inferred from that?
A low ApoA1 value can indicate an increased risk for: • Arteriosclerosis • Heart attack • Stroke. A high ApoA1 value is associated with a lower cardiovascular risk. Symptoms of lipid metabolism disorders are often non-specific, but may include fatigue or weight gain.
What is the ideal time for a test?
The testing should be carried out in a fasting state in order not to influence the values through food intake.
Particularly interesting?
ApoA1 is a more specific marker than HDL cholesterol alone to assess the risk of cardiovascular disease. • The ApoB/ApoA1 ratio is often used to assess the ratio of "bad" to "good" cholesterol. • Genetic factors can influence ApoA1 levels, independent of diet or lifestyle.
