LDL-cholesterol (LDL-C), calculate, measure, replace?
LDL-cholesterol (LDL-C), vypočíst, změřit, nahradit?
V roce 2025 bylo publikováno několik přehledných edukačních sdělení o praktických aspektech lipidemických mezinárodních doporučení, určených k aplikaci v rutinní činnosti klinických laboratoří. První pochází od ADLM - Association of Diagnostics and Laboratory Medicine, druhé sdělení je od HEART UK a ALM (Association of Laboratory Medicine) UK. V obou uvedených publikacích jsou zdůrazněny nedořešené analytické problémy metod stanovení LDL-C, zejména pak interference zvýšených koncentrací triglyceridů a z toho plynoucí úroveň správnosti diagnostických rozhodovacích limitů dyslipidémie. Z obou prací plyne explicitně preferování výpočtu LDL-C před jeho přímým měřením, zejména v amerických a britských doporučeních. To je v rozporu s obvyklou praxí u nás i v Evropě a stojí tedy za zvýšenou pozornost.

Overview
In 2025, several comprehensive educational communications were published on the practical aspects of lipid-related international recommendations, intended for application in the routine activities of clinical laboratories. The first comes from ADLM - Association of Diagnostics and Laboratory Medicine, the second communication is from HEART UK and ALM (Association of Laboratory Medicine) UK. Both publications emphasize unresolved analytical issues in LDL-C determination methods, particularly the interference caused by elevated triglyceride concentrations and the resulting accuracy of diagnostic decision limits for dyslipidemia. Both works explicitly favor the calculation of LDL-C over its direct measurement, especially in American and British recommendations. This is contrary to common practice in our country and in Europe and therefore deserves increased attention.
