Urinary citrate: helpful to predict acid retention in CKD patients?

Acid retention occurs early during the course of chronic kidney disease (CKD). Studies conducted in patients with CKD suggest that alkali supplementation may slow CKD progression. However, the diagnosis of acid retention is challenging when plasma bicarbonate concentration is still normal. In this issue, Goraya et  al. suggest that urinary citrate may predict acid retention in eubicarbonatemic patients with stages 1 and 2 CKD . Although interesting, this claim yet requires confirmation by further studies.
