WebKey Points. Renal tubular acidosis is a class of disorders in which excretion of hydrogen ions or reabsorption of filtered bicarbonate is impaired, leading to a chronic metabolic acidosis with a normal anion gap. RTA is usually due to abnormal aldosterone production or response (type 4), or less often, due to impaired hydrogen ion excretion ... WebRTA. Once the diagnosis of RTA is established, it can be categorized further (Fig. 1) 5. Children with proximal (type 2) RTA should undergo evaluation for other proximal tubule functions (phosphate, electrolytes, glucose and aminoacid excretion) and screening for an underlying etiology (e.g., Wilson disease, cystinosis).
