referred on left ear

Ok so my boy was born on May 1st and was referred on his left ear twice in the hospital and passed on the right.  I have taken him to the commission for children with special health care needs 4 times and they were finally able to do the test this afternoon. Now they are saying he passed left and not passing on right. I'm so frustrated.  I have to take him back again to retest right side.  The reason they weren't able to test before was because of "excessive" wax... Pediatrician said it looked normal.  Just wanting to see if anyone has had a similar experience.  Thanks!
