The assessment of substances in hair is now acknowledged as an effective means for identifying drug and alcohol use. Hair captures a prolonged history of substances as it ensnares biomarkers within its developing strands. Collected close to the scalp, hair offers nearly a 90-day window for detecting alcohol and drugs. The collection process is straightforward, resisting tampering to an extent, and is conveniently shippable.
A 1.5-inch length of roughly 200 hair strands (similar in thickness to a #2 pencil) cut nearest the scalp yields 100mg, which is the optimal quantity for both screening and verification. For tests like EtG, extended panels above ten, 150mg is advised. The weight of the specimen should be measured on a jeweler’s scale. In the absence of scalp hair, an equivalent measure of body hair can be used. 'Head hair' refers specifically to scalp hair, while 'body hair' denotes other hair categories (such as facial, axillary, etc.).
Process Overview
The laboratory processing for a drug test encompasses four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is incorporated into a lab’s system. This involves checking that samples are sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any pending data entries absent from an electronic chain of custody system.
Screening involves a cursory assessment for substances of concern. Though it's a cost-wise means to exclude drug use from the majority of samples, confirmation is needed for a positive screen to hold in legal settings. Any sample that tests positive in the Screening phase demands additional confirmation.
If a sample tests positive in Screening, more hair is extracted from the original specimen and readied for Extraction. Drugs are isolated from hair at a markedly lower concentration compared to other approaches (e.g., urine or saliva), highlighting the complexity of hair drug testing as a methodology.
Confirmation for any positive result from the screening is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that initially test positive are cleansed before confirmation as needed. The progression from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation along with ISO / IEC 17025 standard accreditation.
