Hair testing is regarded as an effective method for detecting drug and alcohol consumption. Hair captures a long-term record of substances by embedding biomarkers within the fibers of the growing strand. When hair is collected close to the scalp, it can indicate substance use history up to roughly a 3-month period. Hair sample collection is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of about 200 strands (comparable to the thickness of a #2 pencil) near the scalp, provides approximately 100mg of hair, the preferred amount for initial screening and verification. For tests such as EtG, add-ons, and those exceeding 10 panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale for accurate specimen measurement. In the absence of scalp hair, an equivalent amount of body hair is acceptable. References to head hair specifically mean scalp hair. Body hair encompasses all other hair areas (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase, where a sample is processed into the laboratory’s documentation system. This process confirms the proper sealing and transportation of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any needed data input not covered by an electronic chain of custody system.
Screening is a preliminary, efficient check for drug presence. Though Screening is cost-effective for excluding drug use in most samples, a confirmation is necessary for court-admissible evidence. Samples with a presumptive positive in Screening require secondary confirmation.
With a presumptive positive result during Screening, additional hair from the original sample is set aside for Extraction. Drugs are extracted from hair at a lower concentration than other samples like urine or oral fluid, underscoring hair testing’s complexity.
Positive screening confirmations are carried out using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation if needed. The full laboratory procedure, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
