Hi,
I know I'm about 6 years behind this debate, but I can't seem to find much on the subject.  

I'm 5 months pregnant and am trying to convince the FBI to allow me to take a polygraph.  I cannot be considered for an FBI position without having a polygraph.  By the time I deliver, the hiring blitz will be over...opportunity lost.  

When I asked why I was not being allowed to take the polygraph, they seemed to be wish washy on the answer.  The bottom line is (like many other things pregnant women are told NOT to do) they just don't know the affects of pregnancy on polygraph.

I have gained medical clearance from my doctor.  I've had no complications thus far with my pregnancy and am in fine health (great blood pressure, taking spinning classes, working full time, eating well).  

And based on the position of the heart rate sensor, there would be no risk of catching the baby's heart rate instead of mine.  If they were monitoring my heart rate with a chest strap and the baby flipped positions so that her heart is in the upper most part of my abdomen, then there MIGHT be interference.  If they are monitoring heart rate with the blood pressure cuff, no worries.  

My beef is that I'm tired of people telling me I can't do things just because I'm pregnant, and they don't have a scientific/rational/reasonable answer.  Telling me NO, just because there's some sort of imagined/feared risk is ignorant.  

I'm willing to take the polygraph and have medical clearance.  That should be enough.  If I fail, that's my loss.  If I pass, the FBI should have no question about me.  Agreed?
