What does the medical abbreviation HOB mean?

Often you need to know the context to determine what medical acronyms stand for. HOB can mean different things.

Some examples are:

• "Head of Bed" and would be used, for example, in an order from the doctor to "Sleep with the HOB raised to 45 degrees after meals if you have acid reflux."
• Another is "Human Osteoblasts". These are cells that work in the formation of bones.
