In the realm of detecting alcohol and drug consumption, hair testing is considered a highly effective method. This technique captures a comprehensive history of substance use by embedding biomarkers in the strands of hair as they grow. By collecting hair samples near the scalp, a detection window of approximately up to 90 days for alcohol and drugs can be achieved. Hair is straightforward to collect, somewhat challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of around 200 hair strands (akin to the thickness of a #2 pencil), cut close to the scalp provides 100mg of hair, representing the perfect sample size for screening and confirmation. For tests like EtG or those exceeding 10 panels, 150mg of the sample is advised. It is suggested to use a jeweler’s scale to weigh the sample. If necessary, in the absence of scalp hair, an equivalent amount of body hair can be utilized. The term head hair pertains solely to scalp hair, whereas body hair covers all other varieties (including facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the first step in integrating a sample into a laboratory's system. The process verifies the proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data collection not included by an electronic chain of custody system.
Screening conducts an initial rapid assessment to spot drugs of abuse. Although it cost-efficiently excludes drug use in most samples, a positive result in the Screening phase necessitates confirmation for court admissibility. Samples that test presumptively positive in Screening require further confirmation.
When a sample is marked presumptively positive during Screening, additional hair is extracted from the initial sample and prepped for Extraction. At this stage, drugs are retrieved from hair at lower concentrations compared to other methods (like urine or oral fluid), highlighting the complexity of hair drug screening.
To confirm any positive screening outcomes, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are employed. Prior to confirmation, all samples with presumptive positive results undergo washing as needed. The entire lab process, from Accessioning through Confirmation, is conducted in accordance with both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Drawbacks:
