I’m really happy how the lecture turned out. Not my best but pretty strong for a first crack at a new topic.
I structured the topic by looking at patients with low, normal and high anion gaps to go along with the high osmolar gap and started with a case of a high osmolar gap paired with a negative anion gap. I have only seen one negative anion gap and that was a case of hyperkalemia and hypoalbuminemia. This case comes from the Canadian Medical Association Journal. The low anion gap is from the unmeasured cation, lithium. The patient had a lithium level of 14.5 mmol/L.
