Do tests go bad if left in hot car?!

[LoveMy2Boys2]

I bought some FRER but have to leave them in the car for a few hours it's 84 outside! Will they go bad if left in car for a few hours? :/

Check the instructions. They tell you the temps to store between so will give you an indication as to if they may be affected or that xxx
