Hair analysis has gained recognition as an effective instrument for identifying substance use. Hair captures a prolonged history of alcohol and drug consumption by embedding biomarkers within the hair shaft. When obtained near the scalp, hair offers roughly a 90-day detection timeframe for alcohol and drugs. It is easy to collect, challenging to tamper with, and simple to transport.
A hair sample measuring 1.5 inches and comprising around 200 strands (similar in thickness to a #2 pencil) closest to the scalp provides 100mg, the optimal amount for examination and verification. For EtG, supplements, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair can be gathered. When mentioning head hair, it exclusively refers to scalp hair, while body hair covers all other hair types (facial, axillary, etc.).
Procedure Synopsis
The four critical phases in the laboratory completion of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample into a lab's system. This encompasses confirming the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry missing from an electronic chain of custody system.
Screening consists of an initial swift assessment for abusive substances. Although Screening is a cost-efficient method to eliminate drug use in most samples, a positive result necessitates confirmation to be accepted in judicial proceedings. Samples showing presumptive positivity in Screening must undergo secondary confirmation.
When a sample appears presumptively positive during the Screening phase, additional hair is extracted from the original sample for Extraction. In this phase, substances are isolated from hair at much lower concentrations than in alternative methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology.
Positive screening results are verified through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 norms.
