mousie  Anion Gap: Na - (Cl + HCO3) = normally around 10-12 +2  
seagull  good to know. I keep looking up the urine values but all it said was "varies", then I threw my computer and yelled "does that vary Mother F****ers. I do feel better now. +57  
_yeetmasterflex  glad I wasn't the only one who got very pissed off at the urine values +4  
fulminant_life  Usually the first thing I look at is whether or not the Cl- is high. Generally if the Cl- is high its going to be a normal gap +7  
henoch schonlein  i think they gave you the urine values bc you can calculate the URINE anion gap which is (Na + K - Cl). In this case the Urine Anion Gap is positive (5). Boards and Beyond mentions that a positive UAG is due to Renal Tubular Acidosis Type 1 (inability of alpha intercalated cells to secrete hydrogen ions). just another approach to answer this q +17  
270onstep1  Actually diarrhea is the "D" in "HARDASS"(reason why I was stuck between Chron's and RTA). Ended up getting it right with RTA.. +1  
talha_s  So the reason this is not Crohn's disease is actually what BnB explains in Renal Tubular acidosis video. Anytime there is a Metabolic Acidosis with intact kidney secretion of H+, the URINARY Anion gap (Na+K-Cl) is NEGATIVE. This is because the excess NH4 that is secreted into urine is combined with Cl-. Therefore, in Crohn's disease and Type 2 Renal Tubular Acidosis, the urinary anion gap is NEGATIVE. In this question, the urinary anion gap is POSITIVE so this would be an example of Type 1 RTA because the kidney can not excrete H+. I got it right by chance, definitely did not understand it in this much detail when I was answering it lol +7
