The use of hair testing has become notably effective in identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering a comprehensive history of substance use over time. When harvested close to the scalp, hair samples can reveal a detection period extending up to about three months for alcohol and various drugs. Collecting hair is hassle-free, challenging to tamper with, and convenient for shipping.
A sample measuring 1.5 inches, consisting of roughly 200 strands (similar in thickness to a #2 pencil) near the scalp, yields 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, or tests above 10 panels, 150mg of the sample is suggested. Utilizing a jeweler’s scale for weighing the sample is recommended. In instances where scalp hair is insufficient, an equal amount of body hair can be utilized. The term head hair refers exclusively to scalp hair, whereas body hair encompasses other hair varieties (such as facial and axillary).
Process Overview
The laboratory processing of a drug test result consists of four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary integration of a sample into a lab's system. This process entails ensuring the sample's seal and shipping integrity, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any additional data needed beyond what's available from an electronic chain of custody system.
Screening is a preliminary assessment for substance markers. While Screening serves as an economical method to dismiss drug usage in most samples, a positive screen necessitates Confirmation for legal admissibility. All samples that show potential positivity during Screening are subject to secondary confirmation.
In the event a sample tests presumptively positive in the Screening phase, additional hair is extracted from the collected sample for further preparation in the Extraction phase. At this point, the drugs are retrieved at lower concentrations than encountered in alternative methodologies (like urine or oral fluid), which contributes to hair drug screening's complexity.
Confirmation of positive results from screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples indicating presumptive positivity undergo washing as required. Every step of the laboratory procedure from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
