  1. Crosstabulation showing the estimated glomerular filtration rate (GFR) stages when the modification of diet in renal disease equation (MDRD) is calculated with a standardized serumcreatinine versus a serumcreatinine as measured by a p10 (10th percentile) or a p90 (90th percentile) laboratory using a Jaffe technique.
