Concordance between LDL-C estimated by various formulas and directly measured LDL-C.

Background: Although direct measurement of LDL cholesterol (LDL-C) in blood is possible, there are several formulas for its estimation. The performance and concordance of these formulas have not been evaluated in Colombia.

Objective: To determine the concordance between LDL-C directly measured using the enzymatic technique and existing methods to calculate it.
