Fear of Poisoning
It's been a weird week.
One guy I'd never met before who works as a tech in another department upstairs came to the nurses' station and started talking to me as if we were good friends. He then asked me if I could run a blood sample on him to check for heavy metals, because he was afraid his wife was trying to poison him. He didn't want to be evaluated, he just wanted me to draw his blood and somehow order a heavy metal screen, off the record.
Then tonight we get toothbrush dude. He'd just bought a new toothbrush, and after using it his gums felt tingly, so he suspected that someone had clandestinely laced it with some sort of toxic chemical substance. He brought the toothbrush with him in a Ziplock bag so that we could have it analyzed.
