Abstract
Ammonium is the most important component of renal acid excretion. A reduced rate of ammonium excretion is the common feature of the group of diseases called distal renal tubular acidosis. We have presented an alternative approach to patients with distal acidification defects based upon the pathophysiology of these disorders. Accordingly, the purpose of this review is to describe a revised classification based on our current understanding of collecting duct hydrogen ion secretion and ammonium addition to the lumen of the distal nephron. We have subdivided these defects into four groups: disorders of the collecting duct proton pump (pump defects); failure to generate and/or maintain an appropriate electrical gradient to favor hydrogen ion secretion (voltage defects); back-leak of hydrogen ions across an abnormally permeable collecting duct membrane (gradient defects), and diminished availability of NH3 in this nephron segment (NH3 defects). These four subtypes can be identified by measuring the urine pH and PCO2 under appropriate circumstances and evaluating the renal excretion of ammonium and potassium.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
