A: It does not affect the outcome of a polygraph exam to test a pregnant woman unless the fetus is making excessive movements or causing pain to the mother during the exam. Many examiners will not test a pregnant woman under any circumstances, but others are ok with testing after the first tri-mester. Some examiners will test only with a note from the woman's physician stating that there are no complications from the pregnancy and that the stress of taking a polygraph would not impact the health of the mother or fetus. Note: Most examiners in Texas are not permitted to test a pregnant person.
