Superior Detection Rates
Our lab is able to use highly effective proprietary methods for getting the drug out of the inside of the hair. While other hair testing labs may leach drugs from the hair, leaving behind or destroying some of the drug in that process, Psychemedics uses its proprietary digestion methods to remove virtually 100% of the drugs from the hair, thereby increasing detection capabilities. In “side-by-side” evaluations with other tests such as blood, saliva, and urine, 6-10 times as many drug users were identified by the Psychemedics testing technology. Use of inferior non-Psychemedics methods can result in false negatives.
Full FDA Clearance
We are the only lab to have FDA clearances for all five drug classes for both head and body hair. We use this to increase the effectiveness of drug testing programs be ensuring that those without head hair are also properly tested. This population makes up approximately 15% of those who apply or are employed today.
We are the only company to develop and patent a process that releases virtually 100% of the drugs from the inside of the hair. This is critical because if you cannot get all of the drug out of the hair, you cannot identify all of the drug users.
Eliminates External Contamination
Psychemedics developed and utilizes the most extensive wash procedure in the industry to remove and / or account for any external contamination (a 3 hour and 45 minute multi-step wash procedure that also includes testing of the last wash with application of wash criteria). Other labs that use less effective washes or do not analyze the wash at all, put clients at risk for making employment decisions based on a false positive result. Numerous studies have demonstrated the effectiveness of the Psychemedics wash procedure and the ineffectiveness of others.
Resistance to Evasion
Psychemedics’ test cannot easily be beaten with cleansers, bleach and dyes, like some other hair tests. While some of these substances will dramatically affect some other labs results, Psychemedics has published data demonstrating that normal use of common hair products or adulterants are not effective on our test to create false negative results.
