Can a drug test detect alcohol in the body?

If it is a 2 panel, 3 panel, 5 panel or 10 panel urine test then no they are not testing for alcohol.  If they swab your cheek, yes...this is called an Alco test.  If they do a blood test the answer is also yes.\n\nhttp://www.onsitedrugtesting.com/drugtest/multidrug.htm\n\nHope this helps!

Standardly Detectable in Urine for 48-72 hours after use.\n\n"Elimination of cocaine is predominantly controlled by its biotranformation. Very low concentrations of cocaine may be detected in urine during the initial several hours, but benzoylegonine persists in urine at detectable concentrations for 48 hrs."\n\nLong term habitual users may have traces of cocaine remain in their system for longer than the standard 3 days.\n\nIn hair tests, it can be detected at different variables, depending on your metabolism.  Increasing doses usually result in increased levels of the drug and metabolites in hair.

The Breathalyzer machine tests for a specific gas that is a by-product of alcohol being metabolized in the human body. In other words, if you drink, this gas will be exhaled from your lungs. There is no way to disguise it by changing the smell of your breath. Since the police are trained to administer the test, you can not trick them or the machine by rapid breathing or blowing real hard. They won't test you if they don't suspect you.

metabolites, or the original compound if its not broken down in the body...  the active chemicals in these drugs are usually broken down by the body and excreated thru urine..  some take longer for the body to break down.  and some are able to dissolve in you body fat (like the THC from pot)  and therefore get slowly released into your blood and then urine over time...  so that we can detect them for alot longer.   THC can be detected for up to 3 months(fat soluble), cocaine 4 days max, since the active dose for acid(LSD) is 100 millionths of a gram, the amount of metabolites is extremely small, so the test is extremely expensive, and RARELY used... if they actually test for it (never heard of it) it wouldnt be detectable for more than 3 days. \namphetamines(exstacy, methamphetamine, STP, )  for up to 5 days max..\n gas chromatography is the method of revealing compounds in the urine.  \n\nthey dont test for prozac or any other selective seratonin reuptake inhibitor(SSRI)..  unless they had a VERY specific reason to do so..  they can find out if your taking prescription drugs that are in the same class as they test for..  they typically test for amphetamine, cocaine, pot, opiates, pcp, and maybe benzodiazepines.  \n\nSOME scripts that will fall in these categories are:\n\namphetamines: adderall, dexedrine, ritalin\n\ncocaine: maaaybe if u ate a ton of novacaine lol\n\nopiates: oxycontin, darvocet, vicodin, codiene, morphine, percocet and most other pain killers that warn about drowsiness on the bottle lol\n\nbenzodiazepines: valium(diazepam), xanax(alprazolam), atavan (lorazopam), .. sonota, ambien, librium, klonapin(clonazepam), and a few more..   \nin this last class of compounds it totally depends on which one..   ranging from 3 days to 2 weeks...\n\nfor thing not listed here...  i suggest you go to wikidedia.com and look up the ones i mentioned, and compare how long i said they would be detectable with the drugs "half-life" (listed in the right column for drugs on wikipedia) .. and compare the two numbers for each to get a feel for it.. and then look up what your wondering..  \n\nhalf life means the time it takes half of it to leave your system.

Yeah there is an amount it takes to set off the test, it's called a cutoff. The cutoff for marijuana is 50 nanograms per milliliters of piss. If it really was 9 to 1 how much piss you  used of hers, you'll be clear unless you smoke ALOT. No, they cannot detect the smallest amount of THC, they don't even test for THC. They test for metabolites that are a result of THC breaking down in your body. There is not a home test available that can detect an amount under that i already stated, that requires extensive urinalysis using a mass spectrometry machine, and they wouldn't show it as positive at levels that small, because it's possible to have that amount of those chemicals in your body without ever smoking, that's why we have cutoffs.

Technically they can't. Doctors can't just run a drug test on your urine or blood all willy nilly, unless you've been notified and agreed to the testing, there is no way they could tell. Unless you go in there all stoned. Thats about it.

Anything really, cigarettes give false positives all the time, probably the worst offenders in your question... Keep in mind that breath alcohol tests are NOT RELIABLE and you can easily get out of a DUI in which that is the only evidence against you...  if you were busted with a breathalyzer you can get out of it because so many things cause false positives and can inflate the readings...

Probably Not. The usual panel tests for:\nAmpethamine\nCocaine\nMethamphetamine\nMarijuana\nOpiates

Not much.  Why would they?  They don't even cover up the booze on your breath from people smelled by people, why would it affect the test?\n\nSeriously, I have a chemistry degree and I ask, why would it?

If you took two hits and haven't taken anything else, then more than likely it won't show up. Urine samples make up a majority of the drug tests used today and they are not that accurate. I used to administer them and there are a certain percentage of "allowable" residues that show up on the tests all the time. These low levels are included because of all the false negatives that would show up if they weren't. Therefore you should be fine. But as mentioned, you should always drink plenty of water to further dilute the sample.

I really don't thinks cause it can test for every thing you have done in the past a six months and that is a long time to go to get clean so the best thing is to either get clean and stay that way or just forget about passing any of those drug tests cause they are to wise to all the new thing people do and use to even pass urine tests they can even tell if you have overloaded yourself with fluids to dilute a substance and will fail you on it.

Diabetes itself can cause a false positive on blood tests for alcohol.  The sugar content of the blood may indicate the same results as a "thouroughly pickled" person.

No way.  Even if some trace showed up, there are cut-off limits for a test to be considered a positive result.\n\nHair is another matter, but you didn't ask about that and no one does that unless they have a really good reason to.  The amount of THC in your system is negligible.  But if it will make you feel better, drink lots and lots of water and do a lot of exercise.

its a achohol blood level test it tell how drunk you are

2 weeks. but there is a loop hole. as long as you dont scratch off any skin onto the mouth swab it might not detect anything. a friend got stoned right before the drug test. he pasted because his mouth was so dry and he rubbed the swab on his teeth, not the inside of his cheek.

Yes they can, however not all narcotics are tested and it depends upon what type of test you will be given.\n\nFor instance the standard NIDA-5 only tests for 5 drugs and while opiates are tested it is only certain ones.  In this test they are looking for morphine and it's metabolites.   Medications such as morphine, Heroin, Codeine, Hydromorphone will show up in this test.  However medications such as Oxycodone, Hydrocodone, Darvon, Fentanyl will not show up with this test as they are not broken down into morphine and need more advanced tests for detection

The generally accepted standard measurement of blood alcohol content (BAC) is given in milligrams of alcohol per 100 milliliters of blood, i.e. mg/100 ml.  An individual's true BAC can only be determined by actual testing of that person's blood in a lab.  However, commercially available tools are used by law enforcement personnel and others to estimate someone's BAC; the Breathalyzer is probably the most commonly used.  BAC can also be estimated with a urine test.  Note that both these noninvasive methods assume a "standard" ratio of alcohol in air or urine to the true BAC.  This ratio is then used to calculate the estimated BAC.  Note that as with many kinds of tests, the results will vary with the circumstances of the test and from person to person.  Nevertheless, Breathalyzer and urine test results are used everyday in law enforcement and alcohol rehab situations, and the Breathalyzer has the force of law when it is used to support charges of DUI, OUIL, etc.
