Hair testing is recognized as an effective medium for identifying drug and alcohol consumption. Hair retains a historical record of alcohol and drug usage by embedding biomarkers within the strands as they grow. When hair is collected close to the scalp, it can provide a detection window of about three months for the presence of alcohol and drugs. The collection of hair is straightforward, relatively tamper-resistant, and suitable for shipping.
A 1.5-inch segment comprising around 200 hair strands (roughly equivalent to a #2 pencil) near the scalp will yield 100mg of hair, considered the optimal sample for both screening and confirmation. For tests involving EtG add-ons or more than 10 panels, 150mg of hair is recommended. It's advised to weigh the sample on a jeweler's scale. Should scalp hair be unavailable, an alternative collection of body hair of equal mass may be performed. The term head hair pertains specifically to scalp hair, whereas body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of drug test results encompasses four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase whereby a sample is processed into a lab's system. This includes ensuring the sample was appropriately sealed and shipped, generating a LAN (Laboratory Accessioning Number), and completing any necessary data entry not handled by an electronic chain of custody system.
Screening is a preliminary procedure to detect potential drugs of abuse. Though Screening is an economical approach to rule out drug presence in most samples, any positive results from this phase require confirmation to be legally valid in court. Samples that are presumed positive in Screening mandate secondary confirmation.
In cases where a sample is tentatively positive during Screening, additional hair is extracted from the initial sample and prepped for Extraction. During this stage, drugs are extracted at a significantly lower concentration than with other techniques (e.g., urine or saliva testing), underscoring the complexity of hair drug testing as a methodology.
Confirmation of any preliminary positive screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, any samples identified as presumptive positives are washed if deemed necessary. The comprehensive laboratory workflow from Accessioning to Confirmation undergoes evaluation under the CAP (College of American Pathologists) Hair criteria and aligns with ISO/IEC 17025 accreditation standards.

Note: Although commonly termed "hair follicle tests," the evaluation centers on the hair strand itself and excludes the hair follicle beneath the scalp.
