Hair testing is regarded as an effective method for identifying drug and alcohol consumption. Hair captures long-term use history by embedding biomarkers in the strands as they grow. When hair is collected near the scalp, it offers up to about a 3-month detection period for alcohol and drugs. Collection is straightforward, reasonably resistant to tampering, and convenient for shipping.
A sample measuring 1.5 inches, containing roughly 200 hair strands (comparable to a #2 pencil size) nearest to the scalp will yield 100mg of hair, the perfect sample for both screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, a specimen of 150mg is advised. The specimen should be weighed on a jeweler’s scale. If scalp hair isn't available, a corresponding amount of body hair may be gathered. Reference to head hair specifically pertains to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The four essential phases in a lab’s drug testing procedure include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's preliminary processing into the lab's system, ensuring the sample was securely sealed and transported, assigning a LAN (Laboratory Accessioning Number), and completing any outstanding data entry absent from an electronic chain of custody system.
Screening involves an initial swift inspection for drugs. While screening is a cost-efficient strategy to potentially rule out drug usage for most samples, any positive screenings must be confirmed to be judicially acceptable. Presumptive positives from Screening necessitate a secondary verification.
If a sample tests as presumptively positive during Screening, additional hair is extracted from the original sample and readied for Extraction. This phase retrieves drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), hence hair drug screening is notably challenging to execute.
Postive screening confirmation is via GC/MS, GC/MS/MS, or LC/MS/MS. Samples identified as presumptively positive are cleansed prior to confirmation as required. The full lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair guidelines and accredited by ISO / IEC 17025 standards.

Note: Commonly mislabeled as "hair follicle tests", these assessments scrutinize the hair shaft, not the underlying follicle beneath the scalp.
