OSORIO, J. H  e  VINASCO, J. DETERMINATION OF LDL CHOLESTEROL LEVELS OF COMPARING THE PRECIPITATE METHOD VS THE FRIEDEWALD FORMULA CANINE. Rev. Med. Vet. Zoot. [online]. 2015, vol.62, n.2, pp.10-15. ISSN 0120-2952.  https://doi.org/10.15446/rfmvz.v62n2.51986.

The objetive of this study was to compare the precipitation method with the method of Friedewald formula for the determination ofLDL cholesterol in dogs. For that, blood samples of 185 overnight fasted adult dogs of different breed and sex were obtained. Blood levels of LDL cholesterol were determined by the precipitation method and later by the Friedewald method. The results were analyzed using one way ANOVA. The precipitate method reported values in mg/dl of: 52.40 average, 2.66 minimum, 132.67 maximum, 130.01 range and 24.29 of standard deviation. For its part, the Friedewald equation values in mg/dl were: 65.19 average, 4.55 minimum, 184.20 maximum, 179.65 range and 31.51 of standard deviation. The p-value in the F test was less than 0.05, indicating statistically significant difference between the two methods analyzed with a confidence level of 95.0%. In conclusion it can be used the precipitated method for determining LDL cholesterol levels in dogs.
