Hair assays have grown in popularity as an effective method for identifying alcohol and drug use. This is because hair strands encapsulate biomarkers within their tissues, offering a retrospective timeline of substance consumption. By acquiring samples near the scalp, one can achieve detection for drugs and alcohol stretching up to a quarter-year. The collection procedure is uncomplicated, challenging to tamper with, and convenient for transport.
A segment measuring 1.5 inches from roughly 200 hair strands (comparable in size to a #2 pencil) closest to the head supplies 100mg, which is the preferred quantity for both screening and validation. When conducting EtG tests, add-ons, or analyses exceeding 10 panels, 150mg is advisable. Using a jeweler’s scale is suggested for weighing the hair. If hair from the scalp isn't available, an equivalent volume of body hair serves as an alternative. The term head hair solely refers to hair from the scalp. Conversely, body hair encompasses all other types like facial or axillary hair.
Process Overview
The primary stages in the lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the starting stage where a sample enters the laboratory's tracking system. This stage confirms the proper sealing and dispatch of the sample, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data tasks absent from an electronic chain of custody.
Screening acts as a preliminary glance for addictive substances. Although Screening is an economical method for excluding drug usage in most samples, a court-valid confirmation is necessary for positive outcomes. Samples testing presumptively positive in Screening demand a follow-up validation.
Should Screening yield a presumptive positive, additional hair is extracted and prepared for the Extraction step. Here, drugs are isolated from hair at notably reduced concentrations compared to other methods (e.g., urine or oral fluid), making hair drug analysis one of the most intricate procedures.
Positive results during Screening undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Samples labeled as presumptive positive are cleaned before this step as required. The absolute laboratory workflow from Accessioning through Confirmation is subjected to scrutiny under the CAP (College of American Pathologists) Hair directive and accreditation in line with ISO / IEC 17025 principles.
