I have been accepted into a Nursing program and have taken two drug tests. Both have come back "outside the parameters". Too dilute to read. I don't understand why this is happening. But yesterday they told me I didn't even have to stay for orientation. They will have to convene the board about me. I'm crushed. I pleaded with them to allow me to do a blood test. "We'll see." Can you give me some reason this test could be doing this?
