Hair analysis is highly regarded for its efficacy in identifying drug and alcohol consumption. It retains a prolonged record of substances through the embedding of biomarkers within the fibers of the growing hair. When extracted near the scalp, it offers a detection period of up to roughly three months for alcohol and other substances. Collecting hair is straightforward, it resists tampering, and is easy to send.
A sample of hair measuring 1.5 inches, consisting of about 200 strands (about the diameter of a #2 pencil) nearest to the head yields 100mg, an optimal amount for analysis and validation. For EtG, additional elements, and/or screenings exceeding 10 panels, a sample of 150mg is advised. Utilizing a jeweler's scale for weighing is suggested. If scalp hair is lacking, an equivalent quantity of body hair may be used. We specifically refer to scalp hair when discussing head hair, whereas body hair denotes all other types (e.g., facial, axillary).
Process Overview
The laboratory process for a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample is initially integrated into the laboratory’s processing system. This involves ensuring the sample’s seal and shipment integrity, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent in an electronic chain of custody system.
Screening involves a preliminary swift check for illicit substances. Although Screening is economical for excluding drug presence in most samples, a positive result must be validated to be permissible legally. Samples indicating a presumptive positive in Screening necessitate a subsequent validation.
Presumptive positives identified in the Screening phase require more hair from the original sample for Extraction. Here, drugs are isolated from hair at a concentration notably lower than in other methods (like urine or oral fluid), which underscores the complexity of conducting hair drug screening.
Any positive outcome from Screening is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Necessary presumptive positive samples undergo cleaning before confirmation. The entire process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair categorization and the adherence to ISO / IEC 17025 standards.

Note: Despite being commonly termed as "hair follicle tests", the analysis focuses on the hair strand and not the follicle beneath the scalp.
