Apolipoprotein B (Apo B) is the main protein in LDL Cholesterol and is the ligand concerned with the uptake of cholesterol.
Elevated levels of Apo B indicate an increased risk of cardiovascular disease even when total and LDL cholesterol levels are normal. Apo B is often tested alongside Apo A-I to determine the Apo B/Apo A-I ratio which is sometimes used as an alternative to the total cholesterol/HDL cholesterol ratio when determining cardiovascular risk. The Randox Apo B assay is based on an immunoturbidimetric method. All reagents are liquid ready-to-use and suitable for use on a wide range of chemistry analysers.
