Apolipoproteins are proteins on the surface of the lipoprotein complex that bind to specific enzymes or transport proteins across the cell membrane.
The normal range is 40 to 125 mg/dl.
Elevated levels may be seen in familial combined hyperlipidaemia and acquired hyperlipidaemia. Elevation may also be seen in cases of acute angina and myocardial infarction.
