In a recent Perspective published in AJKD, Jaime Uribarri and colleagues review the literature on urinary ammonium excretion (UNH4) in an attempt to establish reference values to interpret UNH4 results if and when UNH4 measurements become available as a routine clinical test. They also provide further evidence that the urinary anion gap is not a good predictor of UNH4.
