First off all I would like to say I respect how most of the QL members are responding in this thread.

It’s in your friend’s best interest to get tested and find out his status. If he is worried about the authorities finding out he has requested the test or he may test positive, have him get the test done in another country. At least he would know what course of action to take. Not knowing is worst. I know that there is talk about having to take another medical for visa or RP renewals in the GCC.
