you have to CONSENT to one being done-
it is NOT admissible evidence in court, however if you consent to one and pass then it is admissible...

Police agencies these days most commonly use polygraph examinations as an 'investigation tool', not as a piece of admissible evidence for court. Polygraphs results are not admissible as evidence of a crime by a prosecutor.
But the police can use the polygraph for other purposes. For instance the murder of a wife under suspicious circumstances and the husband says, "it's not me" but the facts don't seem to eliminate him very well either. So the police 'ask' if he will take a polygraph test and the husband can say no or he can say yes, and he will often check with an attorney first. If he says yes, because he feels darn confident he's telling the truth and he passes the test, then the police can have a bit more confidence looking elsewhere for a suspect. If he does not pass the test, the test failure cannot be used in court against him and it can't cause his arrest, but it may validate a police investigator's belief that they need to spend more time checking on the husband.
Sometimes the accused 'wants' to take a polygraph test and the police say no, they don't have a need to provide one. The defendant (probably with his attorney's help) may use a polygraph examiner (check the yellow pages) and may do it himself to see if it comes out favorable in order to offer it on his own as an indicator of innocence.
Polygraph exams are an expense factor so the police don't want to be too extravagant when making offers and trying to set these appointments up. Outside profit making resources are often the ones used.
Such a long story :)

There are private agencies that can administer lie detector tests but it's costly. You can look in the yellow pages for listings.

Police have used this for what it is not suppose to be used for. It can't tell if a person is untruthful, only physiological changes which is thought to be a marker for lying, when it could be inaccurate as hell! Any psychopath could pass one standing on his hands!
Police now use them to often determine who they should charge! I investigated child abuse for 16 years! I didn't need a lie Detector! If you can't do an investigation in which you aren't able to charge because you can't make up your mind, you don't belong on any police force!

Just swear off truth serum as implausible, as well as hypnosis.
You might get lucky enough to get a lie detector test.
Bare your veins.

If 'lie detectors' were reliable, the 5th amendment would prevent requiring you to take one.

Apply for a job which uses it as a criteria for hiring or become a suspect in a felony crime such as murder; you could probably get it done then.

They are not used in criminal court at all. You can hire someone and take one and try and use it as evidence, but it is not reliable enough.
They use them for employment purpose mostly
