Hair analysis is highly regarded as an effective means for detecting drug and alcohol consumption. It captures long-term drug and alcohol histories by embedding biomarkers within the strands of hair as they grow. By collecting hair from the scalp, it can reveal alcohol and drug use within an approximate 3-month period. Hair collection is straightforward, hard to tamper with, and convenient for shipping.
A sample measuring 1.5 inches with around 200 hair strands (similar to a #2 pencil's thickness) near the scalp yields 100mg of hair, which is the optimal quantity for both initial screening and follow-up confirmation. Nonetheless, for EtG, additional screenings, or tests exceeding 10 panels, a 150mg specimen is advised. Employing a jeweler’s scale to measure the sample's weight is recommended. If scalp hair is not available, a corresponding amount of body hair may be gathered. "Head hair" denotes scalp hair exclusively, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The processing of a drug test result in the lab consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial incorporation of a sample into the lab's system, which includes verifying the sample's correct sealing and shipment, issuing an arbitrary LAN (Laboratory Accessioning Number), and finalizing any needed data entry that an electronic chain of custody system does not cover.
Screening involves an expedited preliminary analysis for drugs of abuse. It’s an economical approach for excluding drug usage in the majority of cases, though a positive screening necessitates corroboration for courtroom acceptability. Any samples showing presumptive positivity in Screening mandate subsequent confirmation.
Should Screening suggest a presumptively positive result, more hair is extracted from the original sample and readied for Extraction, where drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation of any positive result from Screening is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples with presumptive positivity undergo washing before confirmation as required. The entire lab process from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation standards.

Limitations:
Note: Commonly termed as "hair follicle tests", the evaluation focuses on analyzing the hair strand itself, not the underlying hair follicle.
