Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair retains an extended history of alcohol and drug presence by encapsulating biomarkers within the strands as they grow. When acquired near the scalp, hair may indicate the presence of alcohol and drugs within a scope of roughly 3 months. Acquiring hair samples is straightforward, less prone to tampering, and convenient for transport.
A sample measuring 1.5 inches consisting of approximately 200 hair strands (similar in size to a #2 pencil) taken nearest to the scalp equates to 100mg, considered optimal for initial screening and confirmation testing. For EtG tests, additional screenings, and examinations exceeding 10 panels, a 150mg sample is advisable. Employ a jeweler’s scale for precise specimen measurement. In the absence of scalp hair, a corresponding amount of body hair might be utilized. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other categories (such as facial, axillary, etc.).
Process Overview
The laboratory analysis in drug testing is comprised of four critical phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts by registering a specimen within the laboratory framework. This phase confirms the sample was appropriately sealed and sent, a LAN (Laboratory Accessioning Number) is allocated randomly, and any outstanding data entry tasks that are absent from an electronic chain of custody are completed.
Screening consists of an initial rapid assessment for substance abuse. While Screening is an efficient method for dismissing drug presence in most samples, a confirmed positive screen is necessary for legal acceptability. Samples flagged as presumptively positive during Screening necessitate dedicated confirmation.
When a sample is deemed presumptively positive in Screening, additional hair from the initial collection is set aside for Extraction. Here, substances are drawn from the hair at a substantially reduced concentration compared to other techniques (e.g., urine or oral fluid), making hair analysis the most challenging approach to conduct.
Verification of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo a wash before confirmation if applicable. The complete laboratory process, encompassing Accessioning to Confirmation, is scrutinized under the auspices of both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Although commonly termed "hair follicle tests," the analysis pertains to the hair shaft and not the follicle beneath the scalp.
