    The objective of this research was to determine the LDL-c values using the Córdova and Friedewald formulas and their relationship with values directly measured by the ADVIA 1800 equipment in adult patients treated at a level IV-3 hospital in Lima in 2017. The study was descriptive, retrospective, and cross-sectional, using 768 results from patients aged 45 to 70 from January 2 to July 31, 2017. The sample consisted of 293 males and 475 females. Regression analysis and the Lin’s Concordance Correlation Coefficient were used for method comparison and accuracy measurement. It was concluded that the triglyceride levels significantly influenced the Friedewald formula, showing moderate concordance in females up to 250 mg/dL and males up to 200 mg/dL. For the Córdova formula, there was poor concordance with the triglyceride values in both sexes compared to the ADVIA 1800 results.
