Hair assessments have gained recognition as an effective means for identifying alcohol and drug consumption. Hair retains a prolonged archive of intoxication markers by embedding them into the fibers of the burgeoning hair strand. When clipped from near the scalp, hair can offer up to about a 3-month detection period for substances. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.
A sample measuring 1.5 inches with approximately 200 hair strands (comparable to a #2 pencil's thickness) next to the scalp yields 100mg of hair, which is optimal for analysis and verification. For EtG, add-ons, or tests exceeding 10 panels, a specimen weighing 150mg is advised. It's best to measure the sample using a jeweler’s scale. If scalp hair cannot be sourced, an equivalent quantity of body hair may be used. "Head hair" pertains solely to scalp hair in this context, whereas "body hair" encompasses all other hair categories (including facial and axillary).
Procedure Breakdown
The key phases included in the lab management of a drug test result are Accessioning, Screening, Extraction, and Verification.
Accessioning encompasses the initial integration of a sample into a lab’s database. This process entails checking that the sample was securely sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and filling out any supplementary data not captured by an electronic chain of custody mechanism.
Screening consists of a preliminary rapid assessment for illicit substances. Although Screening is an economical approach to negate drug usage in most samples, a positive indication necessitates validation to be valid in legal proceedings. Samples yielding a presumptive positive result in Screening mandate further confirmation.
In the event of a presumptive positive outcome during Screening, additional hair is extracted from the original sample and geared for Extraction. At this juncture, substances are drawn from hair at a notably reduced concentration versus other techniques (e.g., urine or oral fluid), highlighting why hair drug testing is the most complex method to execute.
Verification of any positive screening outcomes is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Before affirmation, all presumptive positive samples undergo washing as needed. The comprehensive laboratory sequence from Accessioning through Confirmation is reviewed pursuant to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
