I need help deciphering test restults

[Tickler]

Hello, I was wondering if you guys could help me understand exactly what I am looking at and what constitutes good results vs. bad results and why. I am just trying to wrap my head around all of this stuff so that I can better understand various regs.

An example of a test result is linked below.
