  1. HAGMA. Lactate alone does not explain derangement. Would like to see glucose level to establish if DKA. Could be sepsis driving DKA, which explains the fever, lactate and the derangements. Creatinine normal but would follow closely with urine output to see if acute kidney injury a component. Lastly, measure and calculate osmolality – high osmolar gap suggestive of toxins (salycilates, etyhlene glycol, methanol).
