Identified as a robust method for identifying drug and alcohol use, hair testing captures longer-term substance history by embedding biomarkers within hair strands. If taken near the scalp, it grants approximately a 3-month detection period for drugs and alcohol. The collection process is straightforward, less susceptible to tampering, and simple to transport.
A 1.5-inch hair segment with around 200 strands (comparable to a #2 pencil) from the scalp yields 100mg, which is the preferred amount for both screening and verification. For EtG, enhancements, or panels exceeding 10, 150mg is suggested. It's advisable to use a jeweler’s scale to measure the sample weight. In the absence of scalp hair, an equivalent quantity of body hair can be utilized. Note that 'head hair' refers exclusively to scalp hair, whereas 'body hair' includes other types of hair (e.g., facial, axillary).
Process Overview
The key stages in lab processing of a drug test are: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about processing a sample into the lab’s database initially. This step ensures the sample's proper seal and shipment, assigns it a LAN (Laboratory Accessioning Number) randomly, and finalizes any missing data not available through electronic custody systems.
Screening is a preliminary, swift scan for illicit substances. It's a cost-efficient way to dismiss drug presence in most samples, but results for court validity require confirmation. Samples testing presumptive positive in Screening necessitate further verification.
In the event of a presumptively positive Screening, additional hair from the original sample is set aside for Extraction. During this phase, drugs are extracted from hair at a much lower concentration compared to other test forms (serum or oral fluid), making hair drug testing one of the most intricate methods.
GC/MS, GC/MS/MS, or LC/MS/MS techniques confirm positive screenings. Before Confirmation, all samples testing presumptive positive undergo necessary washing. The complete lab process from Accessioning to Confirmation is scrutinized per CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
