Interpretation
Patients with increased lipoprotein a (Lp[a]) cholesterol values have been associated with increased risk for the development of atherothrombotic disease. Aggressive low-density lipoprotein reduction is the recommended treatment approach in most patients with increased Lp(a).
Lipoprotein-X (LpX) is an abnormal lipoprotein that appears in the sera of patients with obstructive jaundice and is an indicator of cholestasis. The presence of LpX will be reported if noted during Lp(a) cholesterol analysis.
