| description | Protein catabolic rates can be used to estimate protein intake in dialysis patients and determine if dietary protein consumption is appropriate. Protein catabolic rate (PCR) is calculated using the urea-nitrogen appearance rate (UNA). Special consideration including, dietary monitoring of caloric and protein intake, should be given to patients with low protein catabolic rates. [PMID: 2129442] | ||

| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
