Abstract :
Introduction: Low-density Lipoprotein Cholesterol (LDL-C) concentration in blood gives indication of cardiovascular disease risk. LDL-C may vary at various strata of Triglycerides and in metabolic diseases like Diabetes Mellitus. Measurement of LDL-C directly on laboratory instruments is the best method but is costly. It can also be estimated using various formulae. Our study involves the comparison of LDL-C measured directly with LDL-C estimated by calculations using various formulae.
Materials and Methods: Lipid profile data was collected from Central Clinical Laboratory of MIMER Medical College and hospital, Talegaon Dabhade. Serum LDL-C values were estimated by calculation from Triglycerides (TG), Total Cholesterol (TC) and High-density lipoprotein cholesterol (HDL-C) values, using Friedewald’s, Cordova and Cordova, Vujovic, Anandaraja, Puavillai, and Hattori formula. Data of Direct LDL-C and LDL-C estimated by various formulae were compared and correlated at various levels of TG.
Result: Puavillai formula correlates the best with Direct LDL-C at TG
