So I got thed email telling me the facility that ill be going to and its making me nervouse. They use escreen and their description of the cup type says " We’ve designed the lid of our eCup to include a built-in specimen-validity profile. This built-in test strip identifies any donor tampering. The eReader also provides interpretation documentation of possible tampering by testing for nitrates, pH and creatinine in the specimen." So now I'm thinking I'm fucked and need to look into substituting.. anyone had experience with diluting an escreen test?
