One area of concern with widening the number of drugs searched for in the 10 panel drug test is this issue of testing for medicines that can be legally prescribed. Positive results for benzodiazepines, amphetamines, and antidepressants may reveal medical conditions like attention deficit disorder, anxiety disorder or depression. Even if a person provides documentation for the legal right to use a medicine, concern exists about employer discrimination in the future based on revealing sensitive medical information.
Laboratory errors can also result in false positives or false negatives. If an initial drug screen is positive, a second round of more precise confirmatory testing is done to confirm or rule out that positive result. In this case, the results indicate the presence of a drug that the person has not used. If it’s an instant result, the people who administer the drug test usually give the results in terms of positive or negative rather than numeric values. Many instant immunoassay tests don’t display the ng/mL measurements.
A positive result indicates that a drug was detected at or above the reference range for that test. A negative result indicates that the drug wasn’t detected or was below the threshold for a positive test result. For some drugs like amphetamines, the main (parent) drug will be detected in urine. For most other drugs, metabolites will be detectable for a longer time than the main drug. Although it’s possible to use blood or other bodily fluids to conduct a 10-panel drug test, urine tests are the most common.

Amphetamines
Moreover, it’s not clear that employers have to continue to employ someone who uses marijuana, even when prescribed, and a few cases of this nature have attracted national attention. If your first test comes back positive, a follow-up test known as gas chromatography/mass spectrometry (GC/MS) is done for confirmation. This type of test uses the same procedure for getting a urine specimen as the immunoassay. GC/MS results are more expensive and take longer to give results, but they rarely produce false positives. A urine drug test can help a doctor detect potential substance abuse problems.

Quaaludes (methaqualone) are detectable for about two to four days in urine, and four to six months in hair. Methadone is detectable for about three days in urine, and four to six months in hair.

Begin urinating, and then place the collection cup under the urine stream, collecting at least 1 or 2 ounces. Remove the cup, finish urinating, and give the sample to the lab technician.
