Hair testing is recognized as an effective method for detecting drug and alcohol consumption. Hair offers an extensive record of substance use by capturing biomarkers within the strands of growing hair. When obtained near the scalp, hair can reveal a detection period of up to 3 months for alcohol and drugs. It's straightforward to obtain, hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (akin to a #2 pencil), nearest to the scalp provides 100mg of hair, which is ideal for analysis. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. Using a jeweler's scale for weighing is suggested. If no scalp hair is present, the equivalent amount of body hair may be used. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types (like facial or axillary hair).
Process Overview
The primary stages in processing a drug test in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of introducing a sample into a lab's system. This step involves confirming the sample's secure sealing and transport, generating a random LAN (Laboratory Accessioning Number), and finalizing any additional necessary data entry absent in the electronic chain of custody.
Screening is an initial rapid evaluation for substance abuse. Although it is a cost-efficient way to dismiss drug use in most samples, a positive result from Screening necessitates confirmation to stand up in legal settings. Any sample preliminarily positive in Screening must undergo Verification.
Should a sample be deemed preliminarily positive during Screening, additional hair is taken from the original sample for Extraction. At this stage, substances are retrieved from hair at a notably lower concentration than other methods (such as urine or oral fluid), which explains why hair drug screening is among the most challenging methodologies.
Verification of any positive Screening outcomes is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples are cleansed as required prior to Verification. The entire procedure encompassing Accessioning to Verification is supervised by both the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.

Note: Despite being frequently termed "hair follicle tests", the test actually scrutinizes the hair strand and not the follicle beneath the scalp.
