The utilization of hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair serves as a record for prolonged substance use by embedding biomarkers within the fibers of each growing hair strand. When harvested from the proximity of the scalp, hair testing can reveal usage up to a roughly 3-month time frame for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient for transport.
Securing a 1.5-inch section of around 200 hair strands (equivalent to a #2 pencil's width) nearest to the scalp yields 100mg, the preferred quantity for screening and validation. For EtG, supplementary, or more than 10-panel tests, 150mg of the sample is suggested. It is advisable to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, a similar amount of body hair can be obtained. "Head hair" denotes scalp hair solely, while "Body hair" encompasses all other hair categories (such as facial, axillary, etc.).
Process Synopsis
The laboratory evaluation of a drug test result encompasses four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves introducing a sample to a laboratory's system. This step includes confirming the sample's seal and shipment integrity, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent in an electronic chain of custody system.
Screening involves a preliminary evaluation for illicit substances. While Screening is an economical method to discount drug consumption in the majority of samples, a positive outcome requires verification for legal submission. Samples preliminarily flagged as positive in Screening necessitate subsequent confirmation.
In the scenario where a sample receives a potential positive result during Screening, additional hair is taken from the primary specimen and readied for Extraction. At this juncture, substances are drawn out from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring why hair drug testing is the most challenging practice.
Verification of any potential positive outcome from Screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed potentially positive undergo pre-confirmation cleansing as required. The entire laboratory procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and accreditation standards of ISO / IEC 17025.

Note: Often addressed as "hair follicle tests," the test actually processes the hair strand and does not evaluate the follicle beneath the scalp.
