> 500mg/dL

 

Increased in

Genetic hyperlipidemias (e.g. Lipoprotein lipase deficiency, apo C..II deficiency, familial Triglyceridemia, dysbetalipoproteinemia); secondary hyperlipidemias (gout, pancreatitis, acute illness (e.g. in AMI rises to peak in 3 weeks and increase may persist for 1 year); drug use (e.g. thiazides, steroids, amiodarone, interferon).
