Which Methods for Determining Glomerular Filtration Rate Most Strongly Associate with Risk of Progression of Kidney Disease?

In the March 2019 issue of Clinical Chemistry, Professor Andrew Levey and others from a multinational consortium of institutions, published a study titled, "Validation of a Metabolite Panel for a More Accurate Estimation of Glomerular Filtration Rate Using Quantitative LC-MS-MS."  In fact, we have another podcast from one of the authors of that paper available.  But today, we're joined by Dr. Anders Berg, the Associate Medical Director of the Core Laboratories at Cedars-Sinai in Los Angeles, who co-authored an editorial that accompanied the paper. Dr. Berg is here to help us deconvolute the significance of this intriguing study and where this research might lead us in the future.
