Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. It offers an extended timeline of alcohol and drug exposure by embedding biomarkers within the fibers of an actively growing hair strand. When sourced closely to the scalp, hair can reveal drug or alcohol presence over nearly a 3-month period. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.
A 1.5-inch segment comprising roughly 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp yields 100mg, the optimal sample for analysis and verification. For EtG, additional tests, or evaluations exceeding 10 panels, 150mg is advised. It's suggested to weigh the sample with a jeweler’s scale. Should scalp hair be unattainable, a similar quantity of body hair may be utilized. When discussing head hair, it exclusively pertains to scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result is comprised of four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a sample into the laboratory system. This process includes confirmation of the sample’s seal and proper shipping, allocating a random LAN (Laboratory Accessioning Number), and carrying out any supplementary data tasks absent in an electronic chain of custody system.
Screening is an initial rapid assessment for prevalent drugs. While this is a cost-efficient approach to eliminate drug usage for most samples, a positive screen must be validated to hold up in a legal setting. Samples that yield a presumptive positive in Screening require a subsequent confirmation.
Should a sample yield a presumptive positive in Screening, further hair is extracted from the original sample for Extraction. At this stage, substances are drawn from hair at significantly lower concentrations compared to other methods (such as urine or saliva), highlighting why hair drug screening is the most intricate method to administer.
Confirmation of any positive screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples presumptively positive undergo washing before confirmation as appropriate. This entire laboratory sequence, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Note: Frequently termed "hair follicle tests", the analysis is performed on the hair strand, not the follicle beneath the scalp.
