I don't even know where to begin to explain how I started reading up on this, but everywhere I have looked I am getting the same anwsers. Could someone explain in laymen terms what Gram's stain is or does?

There are more links but it's all pretty repetitive. What would be the circumstance of having a Gram test done? What does it tell us if it is Gram-positive bacteria or Gram-negative bacteria? Is this something that is routinely done?
