It means that that person responded positive to have consumed amphetamine
No. = you mean drug screen?
She would most likely test positive for methamphetamine and amphetamine. One of the breakdown products of methamphetamine is regular amphetamine, so a positive result for methamphetamine is basically needed to discriminate a positive amphetamine as due to ingestion of meth vs ingestion of amphetamine. So basically, your sister's test should be positive for methamphetamine also if she did crystal meth.
Yes, could.
That some contamination was noticed and there are going to look deeper.
If you have a positive TCA result in a drug test, it means you have tested positive for taking an antidepressant drug. They can found traces of the drug in your system.
What exactly do you mean by 'causes a positive?' Please rephrase your question. Thank You Is their a nonprescription drug that causes a false positive for benzodiazepine?
If you mean Bactrim, the answer is no.
THC positive.
What does it mean when mucous rare in an urinalysis
Trace a means the first trait that shows up in DNA when talking about urinalysis
There are several components to a urinalysis such as specific gravity, pH, leukocyte esterase, protein, glucose, nitrite, bilirubin, urobilinogen, blood and a microscopic analysis including white blood cells, red blood cells, bacteria, epithelial cells, etc. A urinalysis can be used to diagnose anything from kidney stones to pyelonephritis so in order to know what positive 3 means, you will have to know which component showed the result.
I am assuming that you mean "phenteramine." The answer is YES, both show up in drug screens. Drug screens do not test for specific drugs, only broad classes of drugs like amphetamines and benzodiazepines. Phenteramine, being a sympathetic amine of amphetamine (an "amphetamine congener") will make a drug test show up as "hot" for amphetamine. Same thing with Adderall, which is simply four different salts of amphetamine mixed together. Hope this helps, Dr. Ron
