To make a definitive diagnosis of type I hyperlipidemia, a deficiency of either lipoprotein lipase or apo C-II must be confirmed. The presence of lipoprotein lipase activity may be measured in plasma following intravenous heparin administration (50 IU of heparin per kg body weight) or by analysis of muscle or adipose tissue biopsy samples.
