Would wife take lie detecter test if she cheated?
Lie detector tests are not 100% accurate and although given by law they are not admissibly in a court of law and using a lie detector is not used for public use; therefore it would not make any point for your wife to take a lie detector test.

Does lie detector always give 100 percent correct output whether a person in lying or not?
It depends on how it is designed.But most of them are generally not accurate. For example one such lie detector works on the principle of conductivity of our body.Generally resistance of our body is very high.When we lie we swet(may not be externally but surely our glands swet).Since water conducts electricity the resistivity decreases and so lie is detected. But this is not always true.resistivity of people vary and so it cannot give accurate results always. In the same way each method has its own limitations.
