What is Nutritional and Metabolic Indicator Panel — Glycosaminoglycan, Phosphate, and Miscellaneous Markers?
The remaining OAT analytes provide supplementary metabolic characterisation spanning renal tubular function (phosphate excretion), carbohydrate metabolism, and miscellaneous cofactor pathway markers. Phosphoric acid excretion reflects renal tubular phosphate reabsorption — elevated urinary phosphate alongside low serum phosphate suggests proximal tubular dysfunction (Fanconi syndrome) from cadmium toxicity, Lowe syndrome, or tenofovir nephrotoxicity.
