You all know how much I love acid-base balance, and all things ABGs (See episode 43 from 2018)……so for this episode in renal month, I thought I would tackle a sub-topic of metabolic acidosis that doesn’t as much love as the high-anion gap conditions…..and this is renal tubular acidosis.  We will cover the pathophysiology, what you see on ABGs, and the labs you need order to help diagnosis one of the normal anion gap metabolic acidosis.
