Is a polygraph confidential?

What are the necessary consideration for an effective polygraph testing?
Evidence relevant to the validity of polygraph testing can come from two main sources: basic scientific knowledge about the processes the polygraph measures and the factors influencing those processes, and applied research that assesses the criterion validity or accuracy of polygraph tests in particular settings.
What are the factors that affect the accuracy of the polygraph result?
