Hair tests have gained recognition as an effective resource for identifying the consumption of drugs and alcohol. Hair archives a prolonged history of alcohol and drug exposure by embedding biomarkers within the fibers of the developing hair shaft. When obtained near the scalp, hair can offer a detection period of approximately 90 days for alcohol and drugs. Hair is uncomplicated to gather, relatively tough to tamper with, and convenient to transport.
A sample measuring 1.5 inches from roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the perfect sample size for both screening and validation. For EtG, additional tests, and/or panels exceeding 10, a specimen size of 150mg is advised. We advise using a jeweler’s scale for specimen weighing. If scalp hair cannot be obtained, an equivalent quantity of body hair may be used. When 'head hair' is mentioned, it refers specifically to scalp hair. 'Body hair' encompasses all other hair varieties (such as facial, axillary, etc.).
Process Overview
The quintessential steps consisting of Accessioning, Screening, Extraction, and Confirmation form the laboratory procedure for processing a drug test outcome.
Accessioning is the preparatory handling of a sample into a lab’s system. This procedure involves confirming that the sample was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and inputting any extra data absent from an electronic chain of custody system.
Screening is an initial brisk assessment for drugs of abuse. Screening is an economical method to disprove drug use for most samples; however, a positive screen must be substantiated to be permissible in court. Samples that are tentatively positive in Screening necessitate an additional confirmation.
If a sample indicates presumptive positivity during Screening, more hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are isolated from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening incredibly challenging to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are cleansed prior to confirmation as necessary. Each laboratory stage from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation per ISO / IEC 17025 standards.

Note: Commonly called "hair follicle tests", the analysis actually focuses on the hair strand and not the follicle beneath the scalp.
