Can they identify a specific brand name pill in a urine drug screen?

Two types: Of urine drug screen tests. When you hand your urine over, the first test is an immunoassay "dip" test most of the time.

Can a urine drug screen go back and detect all the meds ive taken the past two weeks?

Can a urine drug screen go back and detect all the meds ive taken the past two weeks?

Depends: Drugs vary greatly in how long they (and their metabolites, which is what most drug tests are looking for) stick around, and tests themselves vary greatly in their sensitivity and specificity to different drugs for different amounts of time. Some drugs (amphetamines, cocaine, short-acting benzos, opioids) are detectable for only a few days while others (marijuana, methadone) can persist for weeks. ...Read more

I've taken 12. 25mg alpralozam tabs sparingly in the past 2 days. I could possibly have a urine drug screen monday or tuesday morning. Will I pass?

3 problems with post: 1) 3 mg of alpralozam in 48 hours is NOT taking it "sparingly." 2) We don't see the dates of posts, so just stating "monday or tuesday" without dates is useless. 3) It amazes me how many people seem heedless that asking doctors for help beating a drug test is asking them to commit a violation of medical ethics & possibly the law. ...Read more

If I took about 3 to 4 mg of Suboxone on sunday about noon. Would it still show up on a urine drug screen thursday about 1 pm?

Depends on what test: The likelihood is low that one dose of 4 mg would show up 4 days later on a drug test, but it depends to some extent on exactly what test they are doing (a screening dipstick test or a formal gc/ms test = much fancier and more sensitive). More important than beating a drug test is dealing with your issues. Your success will not be measured in hiding your problems, but getting help dealing with it. ...Read more
