Urea is a waste product of nitrogen-containing compounds, such as amino acids, metabolized by the liver and excreted in urine. High BUN levels may reflect kidney dysfunction (e.g. reduced ability to excrete urea) whereas low BUN levels may reflect liver dysfunction (e.g., impaired protein metabolism) or malnutrition. BUN was measured using an enzymatic conductivity rate method35 -36 . The analytical measurement range measured via the Beckman UniCel DxC 800 Synchron was 1-150 mg/dL (or up to 300 mg/dL with ORDAC enabled). When measured with the Beckman Coulter UniCel DxC 660i Synchron it was 5-100 mg/dL (or up to 300 mg/dL with ORDAC enabled). The standard reference range for BUN for people aged 5-15 years is 7-18 mg/dL. For those over 15 years it is 6 – 23 mg/dL35 ,36 .

The main independent variable was SUA measured in mg/dL. SUA levels were collected during subject enrolment in the NHANES using a colorimetric method in which uricase oxidises UA to allantoin and hydrogen peroxide (the Beckman Coulter UniCel DxC 800 Synchron chemistry analyzer between 2013 to 2014, the Beckman Coulter UniCel DxC 800 Synchron and the Beckman Coulter UniCel DxC 660i Synchron since 2015). Quality-control procedures' specifics have been disclosed elsewhere [29]. Values are reported in mg/dL and can be converted to μmol/L by multiplying by 59.48.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
