As far as medical conditions are concerned it is the patients right to keep that information a secret. Do you feel that drug testing is forcing you to disclose medical conditions which should remain private?
No I am not talking about illegal drugs.

If you read the question you can plainly see I am speaking in regards to medical conditions.
I know that refusing to take the test is an automatic denial. I also know that you can use synthetic or urine from someone with no medical conditions.
