Contaminated, hemolyzed, grossly icteric, or severely lipemic specimens. General description The 3-hydroxy-3-methylglutary l-coenzyme A reductase (HMG-CoA reductase) enzyme is a ubiquitously expressed glycoprotein that is bound to the membrane of the endoplasmic reticulum (ER), but also projects an active C-terminal catalytic tail into the cytoplasm. Although infrequent, these antibodies may also be observed in statin-naive patients with NAM. Memon S, Ganga HV, Masrur S, Thompson PD. Elevated plasma cholesterol levels are often the result of decreased catabolism and/or overproduction of plasma LDL. HMG-CoA reductase inhibitors include Pitavastatin, Rosuvastatin, lovastatin, Fluvastatin, and Simvastatin (Goldstein and Michael 163). Synonyms. <>>> Consider other causes for elevations >100-fold 1.2. Differential diagnosis of myositis in patients with or without statin exposure.
