I know this is not what you want to here but I don't think it looks good for your sample. I don't know if any of thoses things act as adulterants, probably not, so they probably don't test for them. But the lab tech may see oil floating in your sample and that might set off a few alrams. I am sorry to say that. Maybe if it does raise question but it is negative and nothing is an adulterant then maybe they will retest .
