The Apolipoprotein A1 and B Test measures the levels of Apo A1 and Apo B proteins in the blood, which are essential components of high-density and low-density lipoproteins, respectively. Apo A1, associated with HDL or good cholesterol, aids in removing cholesterol from the bloodstream, while Apo B is directly linked to LDL or bad cholesterol. Elevated Apo B levels may indicate higher cardiovascular risk. This test is often recommended for individuals with a family history of heart disease or when a standard lipid profile does not provide clear insights. By measuring Apo A1 and B, healthcare providers can better assess a person’s risk for heart disease and tailor preventive strategies.

Elevated Apo B levels indicate a higher risk for cardiovascular disease due to the presence of LDL particles that may contribute to arterial plaque buildup. Conversely, high Apo A1 levels are protective and linked to lower cardiac risk. The Apo A1 and B Test is particularly valuable for individuals with existing conditions such as diabetes, renal issues, or thyroid disorders, where cholesterol levels and cardiovascular risk need closer monitoring. Regular assessment of Apo A1 and B levels can aid in managing cholesterol treatment and monitoring the effectiveness of therapies.
