Lipoprotein(a) further invalidates Friedewald formula.
92% had THCA concentrations 30 zgfL. Of the 97 specimens that screened negative at 100 pgfL, 80% had quantitative values for THCA of 30 p gfL. This suggests that reducing the screening cutoff to 50 pgIL will not result in laboratories being flooded with large numbers of specimens for which the THCA concentrations are within 20% of the 15 ig/L confirmation cutoff. The THCA-positive detection rat...

متن کاملValidation of the Friedewald Formula in Patients with Metabolic Syndrome
Currently, the Friedewald formula (FF) is the main method for evaluating low-density lipoprotein cholesterol (LDL-c). Recently, many limitations have emerged regarding its use, including patients with triglyceride levels ≥400 mg/dL, diabetes mellitus, and kidney or hepatic chronic diseases. We analyzed the use of the FF in patients with metabolic syndrome. We selected patients with known metabo...
متن کاملInfluence of intermediate-density lipoproteins on the accuracy of the Friedewald formula.
Values of low-density lipoprotein (LDL) cholesterol (C) according to the Friedewald formula (Clin Chem 1972;18:499-502) were compared with those obtained by lipoprotein fractionation in 98 healthy subjects (control group), 135 specimens from patients with peripheral vascular and cerebrovascular disease (atherosclerotic group), and 45 with chronic renal failure on hemodialysis (CRF group). All h...
متن کاملIs Friedewald formula a good estimation for low density lipoprotein level in Iranian population?
OBJECTIVE Serum low density lipoprotein (LDL) level is an important biomarker for coronary artery disease (CAD). As direct LDL measurement is expensive and not cost effective, especially in a large population, it is estimated by Friedewald formula. Therefore, we decided to compare the direct LDL measurement method with LDL measured by Friedewald formula in a large general population for the fir...
