What does a lab confirmation tell us?
What are the differences between screening VS. confirmation
Screening refers to a preliminary test that yields a qualitative “Positive or Negative” result. Screening can be conducted with a rapid test or using laboratory instrumentation (EIA, EMIT). Both rapid tests and lab screens use the same testing technology, called immunoassay technology. Screening technology is non-specific in that it does not differentiate among the drug class. For example, a positive OPIATE result only indicates that there is some opiate present. It does not indicate whether it is hydrocodone (vicodin), codeine (tylenol 3), heroin, or a combination of these.
Confirmation testing utilizes high complexity instrumentation that yields a definite and specific result. Best practice for confirmation testing involves using either a GC/MS or LC-MS/MS. The results of a confirmation test provide an absolute and definite result that indicates the specific drug/compound present in the urine or oral fluid sample. Premier Biotech utilizes all LC-MS/MS instrumentation for confirmation testing which is considered to be the platinum standard. LC-MS/MS results are defensible in court.

If a patient admitted to taking Suboxone on the first day of the month, than tested positive on the last day of the month, could this be new usage?
Why do some test (T) lines appear more faint than others?
Does the Opiate Strip pick up Oxycodone?
What cross reacts with the standard opiate (OPI) panel?
Why EDDP would be advantageous over a test for MTD?
In many cases, the test administrator would like to know if the individual is actually taking their prescribed methadone and not diverting it. If you are using a standard methadone test you cannot tell the difference as you can sprinkle some MTD from a tablet into the sample and you will get a positive. If you use an EDDP test, you are testing for the MTD metabolite which allows you to make sure the person is taking their recommended dose.
Additionally, you will also pick up the abuser that is not prescribed and is just abusing it.
ETG negative, ETS positive. Would this be a positive for alcohol consumption?
If the Premier Bio-Dip was not inserted until 2 hours after collection. Are results still valid?
Why would THC come back negative in the rapid cup while positive on lab confirmation?
