How to check if a player is one of your followers?

I'm just curious to know if it's possible to see if a player is one of your followers? Not as in, following you into a game but a follower which would affect this total

I've looked through the roblox wiki and have not found much. I assume there probably is a way to do this similar to checking if a player is in a group, though could possibly be wrong...

Any help would be appreciated :) Thanks ^.^
