Analyzing drug and alcohol consumption through hair testing is increasingly recognized as an effective method. The fibers of hair strands, as they grow, encapsulate biomarkers, offering a prolonged record of substance use. When sourced close to the scalp, hair provides an opportunity for detection of alcohol and drugs spanning up to roughly three months. Hair collection is straightforward, hard to tamper with, and convenient to transport.
To conduct screening and confirmation, a sample measuring 1.5 inches with about 200 strands (equivalent to a #2 pencil thickness) near the scalp provides 100mg of hair, considered ideal. For EtG analyses, supplementary tests, or those exceeding 10 panels, 150mg is advised. Using a jeweler’s scale to measure the sample is recommended. Should scalp hair be inaccessible, a similar quantity of body hair is acceptable. Note that “head hair” exclusively refers to scalp hair, whereas "body hair" includes all other types (e.g., facial, axillary, etc.).
Process Overview
The laboratory process of determining a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial stage where a sample is integrated into a laboratory system. Steps include verifying secure sealing and safe shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and executing any leftover data recording not addressed by an electronic tracking system.
Screening involves the preliminary assessment for drugs of abuse. Although Screening effectively rules out drug presence in most samples, a positive result must undergo confirmation for legal validity. Presumptive positives in Screening require further verification.
Should Screening suggest a positive result, additional hair from the primary sample undergoes Extraction. Drugs are extracted from hair in significantly lower concentrations than in alternatives such as urine or saliva tests, underscoring the complexity of hair drug screening.
Confirmation of any positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleansed prior to Confirmation if necessary. The entire lab workflow from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
