Lab Case 44 – Interpretation
1.
High anion gap metabolic acidosis – renal failure, possible sepsis (lactate and ketones not given). Delta gap =1, pure high anion gap metabolic acidosis
Acute on chronic renal failure with moderate to severe hyperkalaemia secondary to possible acute blood loss (??GI – low Hct, low Hb, high platelets), infection, dehydration
Microcytic hypochromic anaemia – chronic blood loss, Fe deficiency, renal failure (however expect anaemia of chronic disease to be normocytic, normochromic)
2.
ECG changes – tall T waves, flattening of P waves, some early lengthening of the PR interval. Possible ischaemia as cause of presentation
