Is there something I can take to pass a 12 panel blood and urine drug test. The only thing I have used is meth.

Is there something I can take to pass a 12 panel blood and urine drug test. The only thing I have used is meth.

Stop using meth: Nothing will work; online stuff's for suckers. The best thing that can happen to you is to acknowledge your meth use and get help. This stuff is treacherous and if you continue to treat this business lightly, you are likely to lose self-control and enter the downward spiral to death. I've autopsied folks like this and yes, they DO claw the flesh off their bodies as they are dying. Save your life. ...Read more

When getting a annual physical does the blood work include a drug test, and does the physical require a urine sample? I'm worried about false positive

When getting a annual physical does the blood work include a drug test, and does the physical require a urine sample? I'm worried about false positive

It does not: You can only be tested for drugs of abuse with your consent. Your physician doing your routine history and physical will not screen you for recreational substances. False-positive drug-of-abuse tests that have medicolegal consequences are very uncommon as the results must be verified by a test using a different chemical principle. And even if you're actually using, your physician is your friend. ...Read more

I took a drug test, but was on my 1st day of period, so blood mixed in urine, will it affect the results?

I took a drug test, but was on my 1st day of period, so blood mixed in urine, will it affect the results?

Drug tests: Usually blood does not invalidate a drug test. I would read the insert if it was on a home drug test, or ask the technician if you had a test at a commercial testing lab to verify whether blood affects the readings. Usually the quality of tests are good enough that the readings stand on their own. ...Read more

Will high bloodsugar cause low creatin levels in urine? I had blood sugar levels of 300 and above and recently took a drug test that came back having low creatin levels.

Will high bloodsugar cause low creatin levels in urine? I had blood sugar levels of 300 and above and recently took a drug test that came back having low creatin levels.

Diluted urine: A low creatinine is not from elevated sugars, but from excessive water drinking, which is common in diabetics. It means you are drinking enough water to dilute your urine. It is not dangerous, but most drug tests will be considered "adulterated" - a failed test - if the creatinine is below 20. Get your diabetes under control asap. Continued high sugars are dangerous to your health. ...Read more

Can a blood drug test determine how much of my. Kolonopin and Vyvanse (lisdexamfetamine) I've taken all month long or is there a.detection period? Why not do a urine test

Yes: If you are taking your medicine on a consistent basis, a Steady State Serum or Blood test should provide a pretty good indication of your adherence to directions. Urine Drug testing only gives a qualitative indication of your medication taking history-in other words-yes you are taking or no you're not taking it. The blood level is an instant snapshot of your blood level so it is difficult to fool. ...Read more

Depends: On the sensitivity of the test. Honesty is the best policy, though. So if you're prescribed these meds, it's most likely u're doc wants to b sure you actually are taking them.

If I used marijuana less than a month ago and I'm using a detox drink for a urine drug test and my menstrual cycle is on will my test be positive?

If I used marijuana less than a month ago and I'm using a detox drink for a urine drug test and my menstrual cycle is on will my test be positive?

Maybe: Marijuana stays in your hair follicles for far longer then the kidneys rate of excretion. In other words, your urine test may or may not be positive for marijuana depending on how long your body needs to excrete THC (marijuana) products. Your menstrual period has nothing to do with the rate of kidney excretion. ...Read more
