Haha! That's what I thought, but I googled capillary blood culture and did find a study about it that said they were able to collect cultures that way, but they had over 20% contamination rate. So, I was wondering if anyone actually does it that way!? It did involve sterilizing the heel, and applying a thin layer of sterile petroleum jelly and then letting the blood bead up on the jelly. I'm 99.99% sure our ER did not follow that procedure-haha.
Coincidentally, the tech who accepted the culture quit the very next day!!
