I don't think it's a matter or trust, I think that it's a lack of communication and expressing your expectations. Had he said that he got a full panel done and he didn't, that would be a trust issue. He never said that he got a full panel so it is a communication on your end and lack of taking control of what people insert into your body. Don't be naive and assume that people will do something that you did not ask them to do

The moral of the story for you would be to communication your expectations.
