Confirmation testing is an important tool for many organizations and individuals. It can step in and answer a lot of questions when an initial screen comes back positive.

We understand that there is always a lot riding on the results of a drug screen. It is important for you to know you are taking the best action. When results come back positive, you may find you have even more questions than before. Ordering a confirmation test can be an excellent way to get more answers through additional scientific data.

A confirmation test is a secondary analysis performed using completely different technology than the initial method. It is used to confirm the presence of drug, or further pinpoint which drug made the initial result positive.

We perform targeted extractions on most of our samples instead of a “dilute and shoot” analysis. This provides a cleaner sample that has optimized the withdrawal of the drug out of the urine. The cleaner the sample, the better the instrument can see it, and the more confident you can be in the identification of the drug and its quantitation.

Our assays are performed by both GC/MS and LC/MS/MS technology. These two techniques are considered the gold standard of the toxicology industry.

Confirmations are excellent for:

  • When a person tests positive for a ‘family of drugs’, such as Opiates, confirmation testing can help pinpoint which drug triggered the test for positive. This is a great tool for when a patient is taking oxycodone and has a positive result for opiates. You may have questions about whether the prescribed oxycodone caused the positive opiate result. Confirmation testing can help identify if there are any other reasons why your patient might have tested positive for opiates.
  • When you want to be absolutely sure a drug is present, a confirmation test will employ a different method of testing than the initial screen. Also, in many cases, the cutoff numbers for confirmation testing are lower than the initial screen cutoffs. Confirmation tests are often completed when any results might be admitted into court as evidence.
  • When you want to eliminate environmental factors as a possible cause of a positive result, confirmation testing can give more detailed information. For example, if your patient claims that they tested positive because they were at a party over the weekend with exposure to marijuana smoke a confirmation test will be able to conclude whether the initial positive was from exposure or consumption.
  • When you want to be sure appropriate, prescribed medication is being taken, regulatory confirmatory testing can help to establish a pattern of use in certain programs where participants should be taking certain medications. This is helpful information for patients in pain management programs, using painkillers like oxycodone and hydromorphone. It is also essential for patients in drug replacement therapy programs, using prescription medications like buprenorphine, suboxone or subutex.
