Recognized for its effectiveness, hair testing is an advanced method for identifying drug and alcohol consumption. The composition of hair allows it to document prolonged exposure to substances by encapsulating biomarkers in the strands during growth. When hair is taken near the scalp, it offers a detection timeframe for substances that can stretch up to around 90 days. This method is easy to administer, challenging to alter, and straightforward to transport.
Obtaining a 1.5-inch segment of about 200 hair strands closest to the scalp yields 100mg, which is optimal for screening and confirmatory purposes. For EtG tests, other add-ons, or panels exceeding 10 tests, it's advised to have 150mg of hair. It's best to use a jeweler’s scale for accurate measurement. Should scalp hair be inaccessible, an equivalent volume of body hair can be collected. Note that 'head hair' refers solely to scalp hair, while 'body hair' includes all other types such as facial or axillary hair.
Process Overview
The laboratory processing of drug test results consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, samples are logged into the lab's system, ensuring correct sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing supplemental data entry absent in an electronic chain of custody.
Screening serves as an initial, economical evaluation for substance presence. Although effective for most cases, positive screenings must undergo further validation to be legally credible. Therefore, samples flagged as positive in Screening require additional confirmation.
Should a sample test positive at the Screening phase, more hair is extracted from the initial sample and readied for Extraction. This phase involves isolating drugs at lower concentrations than in alternative methods like urine or oral fluid testing, highlighting the complexity of hair drug screening.
Confirmatory testing on any Screening positive samples employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all presumptive positives undergo washing if necessary. The entire processing, from Accessioning to final Confirmation, complies with both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 certification requirements.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the analysis focuses on the hair strand above the scalp, not the follicle itself.
