ABSTRACT
Objetive: To determine the reference levels of LDL-cholesterol by an enzymatic method and identify variations in the estimations of analyte according to Friedewald´s formula.Method: A descriptive study was performed from September 2013 to April 2014 in 159 ambulatory patients assisted in the central laboratory of “Saturnino Lora Torres” Teaching Surgical Clinical Provincial Hospital of Santiago de Cuba city, through the application of Kolmogorov-Smirnov´s non-parametric statistical test.
Results: MThe group of patients aged from 15 to 44 (89/56%) predominated, associated with the male sex (121/76, 1%). The lowest reference for LDL-cholesterol was 1, 4 mmol/L, and the highest 4,8mmol/L. The comparison of methods of direct homogenous determination versus the Friedewald´s formula, was evaluated through an analysis of linear regression with r=0, 87.
Conclusions: Reference values obtained for LDL-cholesterol, were not within the clinical ranges established for this analyte. Although the regression analysis showed a good correlation among the LDL-cholesterol values, determined by the direct method and Friedewald´s formula, values were considerably lower in the latter until the cohort made.
