what are the probable causes that a law enforcement agent could use to give you abreath/urion/blood test?

Your question is fairly broad, but probable cause is developed with the given situation, and can be progressive as that situation develops. Let's say, for example, you are driving a car and the officer notice's that you are driving erratically, (left of center, off the roadway edge, weaving, ect.) and becauses of his/her observances, makes a traffic stop. When the officer reaches your door and requests your drivers license, insurance, registration, he/she will also be looking about the interior of your vehicle for what is in plain view or odors. After all, traffic stops are dangerous for the officer making the stop. Usually the officer does not know the person he's stopped and it's unknown if there are weapons in the vehicle, and there is always the risk of the officer getting hit by another motorist driving by and gawking at what's happening. \n      The manor in which your were driving will be a good indicator that the driver of the vehicle is impaired in some way, be it alcohol or drugs, and the officer will most likely request you to exit the vehicle to submit to field sobriety tests, especially if the officer notices the odor of marijuana on your breath, or coming from you vehicle or if he notices any drug items in plain view. (Odors and items in plain view are probable cause.) Three common tests are given: Horizontal Gaze and Nystagmus, One Leg Stand and the Walk and Turn.   The one leg stand and walk and turn tests can actually be practiced by a person in an alterted state, however, the horzontal gaze and nystagmus is an involuntary body reaction and cannot be practiced. The officer will instruct you to follow his finger or a pen, moving your eyes only. What he/she will be watching for is the lack of smooth pursuit of the eyes. If a person is intoxicated or using drugs, the eyes will jerk back and forth as the person is trying to follow the movement of the pen. This test is not a 100% guarantee that the person is drunk or on drugs, but is a real good indicator. All states require licensed drivers to submit to a secondary test as a condidition of holding a drivers license, and failure to submit to such secondary test usually is a mandatory suspension of your driving privileges. Each law enforcement agency designates in their policy and procedures manual which secondary test will be given.... blood, breath or urine. Should the officer test you by breath and the test result is "0", the officer may request you to submit to a blood test or urine test. If you refuse which you have a right to do, the officer will need to obtain a search warrant for your blood or urine, and his probable cause for the search warrant would be the manor in which you were driving, the results of the field sobriety tests, his/her observances inside your vehicle, any smells that were noticed and the result of the intoximeter's test result. \n      There are so many varibles that come into play it's difficult to answer you with out being so long winded and more specific information in your question. Hopefully I have helped you in some way.

i work in the healthcare field, and to the best of my knowledge, an employer can ask you to take a physical. however, i am pretty sure there would not be any blood testing. ive never encountered one. regardless, you are protected by federal law against discrimination of any kind in employment, so  if they did find out, and terminated you, or used that as an excuse to hire you in the first place, youve got yourself one hell of a case if you choose to sue.

drugs.  find a cheap alternative to your current method of investigation.  asking total strangers online is not the way to plan your life.  drugs. that's the ticket!

Being in Law Enforcement, I will tell you that every Agency has it's own set of guidelines, traffic violations of the non serious matter will not hurt you in most cases. Those of a serious matter will surely not be good. Any type of criminal background will be a negative for you. It simply comes to a decision by the Supervisors as to what the crime amounts to and how the disposition was handled.

i'd think that maybe they are really buissy.  if it was positive i dont think they would mis place it and they would have you come in and take more blood probalby for another sample would be my guess.  good luck.

A search warrant! they might say probable cause but is just to get them in the door! the constitution of the united states tells about unlawful search and seazure. Hope I spelled that last word right!

This can be done by a blood test.

Bowel irritability and kidney problems can arise from blood in urine.  Go back to your doctor and ask for a battery of tests.  Better safe than sorry.

Its possible...I wouldnt worry too much, I would assume that the blood center who drew the blood tested it for a variety of dieases before they would hand it over to the hospital.

Probable cause. The officer sees, hears, or smells something suspicious. You have every right (or at least you used to) to refuse. Then they can arrest you for disobeying a police officer and search your vehicle anyway.\n\nsome legal examples:\n Law enforcement officers may conduct a warrantless search of a vehicle if there is probable cause to believe that the vehicle contains evidence of a crime, and it is likely that, due to exigent circumstances, the vehicle will be unavailable for search by the time a warrant is obtained.  (Katz v. United States, 389 U.S. 347, 357 )\n\nwarrantless searches of automobiles are justified only when two factors are present: probable cause to believe that the automobile contained contraband, and exigent circumstances associated with the automobile. (Carroll v. United States, 267 U.S. 132 )\n\nIf consent is refused, you must have reasonable suspicion of unlawful activity to detain. The reasonable suspicion factors must establish the reasons for the detention. You must be able to articulate each observation that is a potential indicator of drug trafficking or use. (United States v Dewitt 946 F. 2d 1497)\n\nFor more info on roadblocks, see my link:

First of all...to all the people that said "duh"...Your answers to this question were 100 times as stupid as the question itself.  The answer to the question is that they will only find out if you have AIDS, if you've done marijuana, or other drugs if they run a specific test for it.  They don't put the blood in a machine and have it run all the tests that are known.  When you get blood drawn, there has to be a reason...They might be looking for how your kidneys or liver are functioning, so they will test for that.  If they want to know if you have been taking drugs, they can test for that as well.

First off, thanks for staying drug-free and passing the test!\n\nNow, please ignore the foolish advice to drink 3 quarts of water -- it's possible to get water poisoning by drinking too much water and it can be FATAL!\n\nYour problem is not unusual at all, actually.  Many people have problems doing this in the presence of another person, especially a stranger.  However, for legal reasons (that actually protect YOU if you're drug-free!) a monitor is required to view the flow of urine from the urethra into the cup and to certify such under penalty of perjury.  In some non-justice related testing, such as pre-employment screening, alternative methods are used to verify that the sample is legitimate such as taking the temperature of the sample immediately after collection.  Unfortunately, this won't work in your case.\n\nYou might ask if a blood test could be used in lieu of the urine test.  Not all jurisdictions allow this and those that do may require you to pay the increased cost for blood testing but it's worth asking the question.\n\nFailing that, you're going to have to work through this on your own.  Try to psyche yourself up prior to the test.  Remind yourself that you ARE drug-free and this test is going to PROVE it to the world.  Picture yourself having successfully completed your probation or parole and NEVER having to do this again.  Anything that will ease the mental block for you.\n\nOnce you get a couple of clean tests, the folks there will come to accept the fact that you have problems doing this and may ease off the pressure a bit.  Actually, they deal with this on a daily basis but there's no way to separate the scammers from the folks with difficulty in providing a witnessed sample until they become accustomed to dealing with you.  In the best case scenario, they might use the same witness each time to help make it a bit easier on your though local policy may prohibit this.\n\nIt does help to have a bit extra to drink prior to reporting to the testing facility.  An extra cup of coffee or can of soda or two will usually suffice.  Don't overdo it though as excessive intake can be dangerous as I mentioned earlier.  It's also possible that the test could come back as "diluted" which would require you to retake the test.  This is a common ploy for drug users to try to cheat the test but it never works and if you're truly drug-free you don't want them to think that you're trying to get one over on them.

I think it can cause a positive reaction to methamphetamine (aka crystal meth, ice), and the drug test they may be using might test for that drug along with cocaine. I would ask the company that does the testing exactly what drugs were tested for the one that brought you up as positive. Are you a member of a union? It's time to seek legal guidance. If you can't afford a lawyer, then go to the free legal services in your city or town.

They need more probable cause than a nervous look. Proving a civil rights violation can be very difficult unless you can document the cop's action.
