Values for density ranges of the lipoprotein classes are approximate. The classes may be defined differently by different researchers, in part because class definitions depend on the number of subclasses into which the lipoprotein fractions are divided. chylomicron change measurement chylomicron measurement clinical_measurement_ontology mshimoyama
