Can I sue my employer for unprofessional drug testing?

My brother and I work for the same company and we recently had a surprise drug test. While we were waitng I had an emergency to run to and left. My brother stayed and was afraid he was going to fail his drug test so he picked my paperwork up and took my drug test. The owners wife was doing the drug test at the facility and never asked for any type of I.D. I was reviewing DOT laws about drug testing and my company didnt comply to the rule about identification.

Can I sue?
