Recognized as an effective method for identifying substance use, hair testing provides an extended timeline for detecting alcohol and drug presence by capturing indicators within the strands. When sourced near the scalp, hair offers a detection range of up to 3 months for such substances. Collecting hair is straightforward, challenging to tamper with, and convenient for transport.
A sample of 1.5 inches consisting of roughly 200 hair strands (comparable to the girth of a #2 pencil) from the scalp yields 100mg, which is optimal for both screening and verification. For tests like EtG, add-ons, or those exceeding 10 panels, 150mg of the sample is advised. It is suggested to measure this on a jeweler’s scale. In the absence of scalp hair, collecting a similar quantity from body hair is an option. When discussing head hair, we focus solely on scalp hair. Body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The key phases in lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is concerned with the preliminary assimilation of a sample into the lab's system. This step involves confirming the sample’s seal and shipment accuracy, assigning it a random LAN (Laboratory Accessioning Number), and completing any data entry that was not supplied by an electronic chain of custody system.
Screening is a preliminary drug abuse assessment. Although cost-effective in excluding drug use for most samples, a positive screen necessitates confirmation for legal proceedings. Any samples that show potential positivity in Screening require additional confirmation.
Should a sample exhibit potential positivity during Screening, further hair is extracted from the original sample for the Extraction phase. Here, drugs are extracted from the hair at significantly lower concentrations relative to other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.
Confirmation of any positive findings from Screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All potentially positive samples undergo necessary washing before confirmation. The entire lab procedure from Accessioning through Confirmation undergoes scrutiny under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditations.
