WebNational Center for Biotechnology Information WebA useful tool to predict the likelihood of a drug to cross the hemofilter membrane is the sieving coefficient. This term is defined as the ratio of drug concentration in the ultrafiltrate to the pre- filter plasma water concentration of the drug. If the sieving coefficient is close to 1.0, the drug has relatively free passage across the filter.
