OSORIO, José Henry; SUAREZ, Yirly Johanna  e  PEREZ, Jorge Enrique. VALIDATION OF FRIEDEWALD'S FORMULA FOR DETERMINING CATTLE LIPID PROFILE. Biosalud [online]. 2012, vol.11, n.2, pp.70-76. ISSN 1657-9550.

Objective: To validate Friedewald's formula for determing LDL cholesterol levels in cattle, species with HDL metabolic pattern. Materials and Methods: One hundred (100) blood samples from different age, race and gender cattle were taken. After removing the serum, the LDL cholesterol levels were determined using the direct method and later the same values were determined using Friedewald's formula. Results were statistically analyzed using one-way ANOVA. Results: The direct method reported values (mg/dl) of average, minimum range, maximum range, and standard deviation of 40.769, 2.438, 126.751, 29.814, respectively, and Friedewald method results showed minimum, maximum and standard deviation averages of 34.659, 1.349, 145.31, 29.108, respectively. The value of P in the F test Direct in the comparison of the direct method and Friedewald's method was greater than or equal to 0.05 (0.154), reason why no significant difference was evident at a level of confidence of 95% between the values obtained through the two methods. Conclusion: Friedewald's formula can be used for determining LDL cholesterol in species with HDL pattern.
