Gee, and here I sit getting PTSD from the online scholars who think learning a few Greek words turns them into a world-class John Calvin or Martin Luther but who couldn't parse a participle to save their lives. At some point I got used to it, though - and then I realized why ACTUAL scholars don't engage the rank and file with discussions. And that's just in my religion degree - which admittedly is an abstract field open to some level of interpretation, but it's NOT as complicated as folks make it. When God makes an OT promise to Israel, it has nothing to do with 21st century America yet that's a controversial take right there.
Then there's the laboratory.
Let me put it this way for you: NURSES often don't know laboratory beyond the basics, and I'm fine with that. I don't know their pharmacological dosing like they do because it isn't my field - yet I HAVE been to Med school and HAVE taken Pharmacology, so I have a better handle on it than almost any lab tech you're going to know. But it's not my place to make that call, either.
About a year ago, I called up a nurse with a notification. What had happened was my instrument was reporting a potassium incompatible with human life (>10.0) and a calcium below linearity (<5.0). I knew immediately what had happened. Someone had drawn blood in one of those purple top EDTA tubes and poured it into a green top tube with lithium heparin anticoagulant. The EDTA bound up the calcium (which makes blood clot) to prevent clotting - and the material is actually called POTASSIUM EDTA in the tube (K2EDTA or K3EDTA). So it spiked the potassium and lowered the calcium. (One does not have to be particularly bright to understand what I'm saying here).
So I call up the nurse and tell her, "It appears that someone drew the purple top tube and then put some of it into the green top tube." I'll never forget her response: "You can tell that?" I'm thinking, "You're a nurse and don't already KNOW that?"
And yes, folks, we can tell if you just run hot water into the cup and pass it off as urine. The specific gravity and lack of creatinine are dead giveaways.
Don't think I'm picking on nurses, though. Quite frankly, many of them keep the more inept doctors from killing you.
