Abstract:Comment is made on 7 methods with respect to replicate analysis and correlation with results of the Schoenheimer-Sperry determination of serum cholesterol. Estimates of variance are tabulated for 5 of the methods in terms of twice the coefficient of variation (2CVx); values range from 6.2% to 11.8%, averaging approximately 10%. For cholesterol standards, reproducibility of color development is somewhat better for standards equivalent to more than 200 mg./100ml.; the range of values for 2CVx is 3.8% to 39% abov… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
