Is it posible for the drug ice not to show positive in a urine analysis if used on a regular basis?

Ironically, the drug that stays in the system longest is the most innocuous, marijuana. Ice (methamphetamine), cocaine, heroin will only test positive for a couple days after the last time they were taken. Marijuana can last up to 6 weeks. These times vary somewhat based on dosage and frequency of use before the test and the metabolism and body chemistry of the test subject.\n\nPS: Ice is an incredibly addictive drug that can cause permanent changes in brain structure with very limited use. It is still rising in popularity and is already causing more problems than heroin and cocaine combined. Just stay away from it. And I say this as a person who is generally pro-legalization when it comes to drugs. Meth makes cocaine seem like icing sugar.

No, You have to have done the drug for it to be in your system. If the police thought the house was a danger they would have condemed it after it was raided.

I worry if it mine is dark, I'm not getting enough fluid and the urine is too concentrated or there may be a kidney problem.  When I was a medical lab scientist the accepted 'standard' colour for screening urine samples was  'straw-coloured' (the dried grass sort, not what you drink through!), anything else usually led to further testing.

There have been no reports of this product causing a false positive drug screen.\n\nDrug screening processes have grown more sophisticated. They don't test for remnants of chemical byproducts in the system anymore. They now test for traces of the drug itself. We get people in our police dept all the time who fail a drug test but say "I just took some Sudafed." The response is "Cool. We don't test for Sudafed. We test for methamphetamine. You failed."

Continue to deny any use of drugs, ask for another test, they have to administer it. There are a lot of false positive results with most of the urine tests employers use as a screening tool, because they are using the cheapest tests they can find (in most circumstances). Some medications you take can result in a false positive, be sure to let someone know exactly what medications you are taking.

A specimen of urine will be good for about 24 hours at room temperature. You can prolong that by refrigerating it, but most tests for a drug screen will record the temperature of the sample. You can also freeze your sample and it will be good for a very long time. If you want to use it for a pregnancy test you will need to use fresh urine to make sure the enzymes and hormones are in proper order for testing.

Yes, especially if you are taking a narcotic (pain killer) or some sleeping pills.  Testing positive shouldn't be an automatic reason for termination of employment.  Most people who have a positive test are notified that they tested positive and are allowed to explain that they are on prescription medication.  The employer (or rather the agency that actually performs the test) will then contact your physician for a list of your medications.  If the medications match what you came up positive for (IE if you come up positive for cocaine and you have a prescription for lidocaine) then you will pass and your employer is usually never notified that you were on meds, they will simply be told that you passed.  However, if you test for something that you don't have a current prescription for then you will fail.

im a medical assistant at a drug testing facility. we have to tell people that the test in inconclusive or "non-negative" because we cant tell you that its positive. more than likely it will be if they sent it to the lab though. some medications, however, do show up (pain med, etc.). if it were diluted (too much water) it would have showed negative on a quick screen. (those only show neg or positive). e-mail me if you want to.

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 would have though they woule be testng for more regular drugs - recreational - HOWEVER ephedrine may give a false positive for other drugs, specifically methamphetamine. It does depend on the test they use.\n\nAs for how long, 2-4 days seems to be atypical guestimate from most of the websites I have seen in the past.  The previous answer MIGHT be correct but it seems to contradict most of the other sites I have seen. I will try and check some more. Here is a list of others which might be of use....\n\nAlcohol                                6-24 hours\nAmphetamines                           2-3 days\nBarbituates                             1 day to 3 weeks\nBenzodiazepines                3-7 days\nCocaine                               2-5 days\nCodeine                               3-5 days\nEuphorics (MDMA, Ecstasy) 1-3 days\nLSD                                         1-4 days\nMarijuana (THC)                 7-30 days\nMethadone                            3-5 days\nMethaqualone                          14 days\nOpiates                               1-4 days\nPhencyclidine (PCP)              2-4 days\nSteroids (anabolic)                 14-30 days\n\n\nThe following medical products (including ephedrine) can lead to "false positives" and might be wroth bearing in mind as an emergency excuse....\n\n    * Ibuprofen (Advil, Motrin)\n    * Midol\n    * Nuprin\n    * Sudafed           The one you are interested in - false pos for ephidirine/meth\n    * Vicks Nasal Spray\n    * Neosynephren\n    * Ephedra and Ephedrine-based products (often used in diet products)\n    * Detromethorphan\n    * Vicks 44

Nope.  If you think you can fool a drug test, you're probably still high.  \n\nYour best bet is to come clean with whomever is administering the test BEFORE you pee in the cup.\n\nThen, quit smoking and get a life.

It depends what is being evaluated. In drug testing, urine can be kept for a long time, years even.  For all testing, if it is stored properly - long periods may elapse as well.  If the pourpose is to evaluate for infection - immediate evaluation (same day or 24 hours) is best.

I believe when you have a drug test, you list the prescription medications you are taking.  I wouldn't think it should be a problem for you.

Yes, most likely this drug will show up on an abused drug screening, particularly if it is taken daily.  However if you have a prescription for this medication and disclose this before the test a positive result will not be held against you.

Your best thing to do is to ask the doctor or pharmacist. I couldn't find a conclusive answer for you either. It really is not a problem even if SSRI's show up on a urinalysis though. They are prescription medications,not anything illegal. Sorry I couldn't be of more help. Zoya.

Benedict's reagent can be used to test for the presence of glucose in urine. Glucose found to be present in urine is an indication of diabetes. 5.0ml of Benedict's qualitative solution is mixed with 0.5ml of urine and the mixture is put in a boiling water bath for 5 minutes. The results are recorded thus:\n\nno precipitate — \nGreen a trace \nyellow + \norange ++ \nred +++ \n\nOnce sugar is detected in urine, further tests have to be undergone in order to ascertain which sugar is present. Only glucose is indicative of diabetes.
