<prompt> In a 32yr old male presenting with the following blood chemistry Na 135,K 5.0, HCO3- 14.0, Cl- 116, PO4-- 5.0, S04-- 5.0, Mg 2.0, Ca 8.0 the anion gap is :20151310  <response>: We cannot get the answer by using the calculation we have all been using till now i.e. -Anion gap - then the anion gap would be - 5But 5 is not an optionIn all the books I have looked for i.e., Harrison, Nelson Ganong, Guyton, C.P.D.T., Cecil; anion gap is calculated inthe similar way except for Bailey where anion gap is calculated as follows:Anion gap - Using this anion gap isequal to 140 - 130 10
