Default Merck Manual, re: HDL > 80

This might be more helpful:

Quote:
Low HDL:

[...]
Alcohol raises HDL cholesterol but is not routinely recommended as a therapy because of its many other adverse effects.
Quote:
Elevated High-Density Lipoprotein Levels

Elevated high-density lipoprotein (HDL) level is HDL cholesterol > 80 mg/dL (> 2.1 mmol/L).

[...]

Primary causes are single or multiple genetic mutations that result in overproduction or decreased clearance of HDL. Secondary causes of high HDL cholesterol include all of the following:

Chronic alcoholism without cirrhosis
Primary biliary cirrhosis
Hyperthyroidism
Drugs (eg, corticosteroids, insulin, phenytoin)

The unexpected finding of high HDL cholesterol in patients not taking lipid-lowering drugs should prompt a diagnostic evaluation for a secondary cause with measurements of AST, ALT, and thyroid-stimulating hormone; a negative evaluation suggests a possible primary cause.
