Dyslipidemia refers to abnormalities in serum lipid levels, including high or low levels of total cholesterol, triglycerides, LDL cholesterol, and HDL cholesterol. These abnormalities can be inherited, acquired, or secondary to other primary conditions. Dyslipidemias are classified based on the pattern of lipoproteins in electrophoresis or ultracentrifugation testing.

1. Dyslipidemia
Abnormalities in the serum levels of LIPIDS, including
Hyperlipidaemia
overproduction or deficiency. Abnormal serum lipid Conditions with abnormally elevated levels of
profiles may include high total CHOLESTEROL, high
LIPOPROTEINS in the blood. They may be inherited,
TRIGLYCERIDES, low HIGH DENSITY LIPOPROTEIN
acquired, primary, or secondary. Hyperlipoproteinemias are
CHOLESTEROL, and elevated LOW DENSITY LIPOPROTEIN
classified according to the pattern of lipoproteins on
CHOLESTEROL
electrophoresis or ultracentrifugation
