LDL-cholesterol: Friedewald calculated versus direct measurement-study from a large Indian laboratory database
Abstract
Background: Validity of Friedewald formula (FF) in patients with serum triglycerides (TGs) 200) underestimates the LDL calculated by FF particularly at LDL values 130 mg/dl. Conclusion: We suggest repeating the LDL by direct assay techniques particularly in patients with TG >200 and when LDL 130. This helps in correctly stratifying the coronary artery diseases′ (CADs′) risk and goals of treatment.
