Journal ArticleDOI
HFE C282Y homozygosity is associated with lower total and low-density lipoprotein cholesterol the Hemochromatosis and Iron Overload Screening study
Paul C. Adams,James S. Pankow,James C. Barton,Ronald T. Acton,Cathie Leiendecker-Foster,Gordon D. McLaren,Gordon D. McLaren,Mark Speechley,John H. Eckfeldt +8 more
TL;DR: The Hemochromatosis and Iron Overload Screening study as discussed by the authors showed that C282Y homozygotes had significantly lower mean total and low-density lipoprotein cholesterol concentrations than wild-type subjects.
Journal ArticleDOI
EDTA-plasma vs serum differences in cholesterol, high-density-lipoprotein cholesterol, and triglyceride as measured by several methods.
TL;DR: It is concluded that P/S ratios vary by analytical methods, and that HDLC ratios tend to be larger in magnitude and in the opposite direction from TC and TG, which lead to significant biases in computed disease risk.
Journal Article
Matrix effects on proficiency testing materials. Impact on accuracy of cholesterol measurement in laboratories in the nation's largest hospital system.
H. K. Naito,Yun-Sik Kwak,J. L. Hartfiel,J. K. Park,E. M. Travers,G. L. Myers,J. W. Ross,John H. Eckfeldt,A. E. Hartmann +8 more
TL;DR: The results showed significant matrix-effect biases with the CAP Surveys materials with six of the eight major peer groups, despite the fact that accuracy of cholesterol measurements was maintained with fresh serum samples, and collaborative efforts are needed to improve PT fluids to analytically behave more like fresh, human serum.
Journal ArticleDOI
Serum β-Trace Protein and Risk of Mortality in Incident Hemodialysis Patients
Tariq Shafi,Rulan S. Parekh,Bernard G. Jaar,Laura C. Plantinga,Pooja C. Oberai,John H. Eckfeldt,Andrew S. Levey,Neil R. Powe,Josef Coresh +8 more
TL;DR: The serum level of β-trace protein is an independent predictor of death and cardiovascular disease mortality in incident hemodialysis patients.
Journal ArticleDOI
ARIC hemostasis study--II. Organizational plan and feasibility study.
TL;DR: A pilot study was carried out to test the feasibility of an integrated organizational plan to increase efficiency and minimize errors in the blood collection and processing system suitable for the ARIC multicenter hemostasis study.
