Do you have any thoughts on why there are so many varying opinions on what lab values actually confirm a diagnosis? For example many very well respected experienced surgeons and endocrinologists correct calcium for albumin even when it’s not low. This can bring a high calcium down to normal or even low and possibly miss a diagnosis.
It's a great question. It seems like we should all be able to agree on which lab values are normal. Unfortunately this is not the case, and there are a few reasons.
First, when the lab gives the results, it gives a "normal range" - but this is looking at all humans in aggregate. A normal human can have a calcium of 10.5 mg/dl when she is 20 years old, but should not have that when she is 80...
