Cholesterol measurement and current guidelines [PDF]
Vnitřní lékařství, 2022 The concentration of total cholesterol has so far been part of the SCORE tables for estimating the risk of cardiovascular events; in the new SCORE2 tables, it has already been replaced by non-HDL-cholesterol. Total cholesterol continues to serve as a guide for the presence of dyslipoproteinemia and is necessary for the calculation of LDL-cholesterol ...
