Hair analysis is now recognized as a valuable method for identifying substance and alcohol consumption. Hair can preserve a detailed historical record of substance use by encapsulating biomarkers within its structure as it grows. When hair is collected near the scalp, it can offer an approximately three-month window for detecting alcohol and other substances. Hair is easy to collect, somewhat challenging to tamper with, and straightforward to transport.
A 1.5-inch portion comprising around 200 strands of hair (equivalent to the width of a #2 pencil) closest to the scalp will yield 100mg, which is the optimal amount for both screening and confirmation tests. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the specimen is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair can be used. References to head hair specifically mean scalp hair, while body hair encompasses all other types (like facial, axillary, etc.).
Process Overview
The core steps in processing a drug test in a lab setting are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is integrated into the lab’s workflow. This phase includes ensuring that the sample’s packaging and shipment were secured properly, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any missing data entry not covered by an electronic chain of custody.
Screening provides a preliminary examination for substances of abuse. While it is a cost-effective step to potentially exclude drug use, a positive screen must be confirmed for legal proceedings. Samples that show presumptive positivity require additional confirmation.
If initial Screening suggests positivity, further hair is taken from the primary sample for Extraction. During this phase, drugs are isolated from hair at much lower levels than other methods (such as urine or oral fluid), highlighting why hair drug analysis is particularly challenging.
Confirmation of a positive initial result is through GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation, presumptive positive samples are washed as required. The entire laboratory process from Accessioning to Confirmation is overseen under the CAP (College of American Pathologists) Hair guidelines and adheres to ISO / IEC 17025 standards.

Limitations:
Note: Despite the term "hair follicle tests" being commonly used, the analysis targets the hair strand itself rather than the follicle beneath the scalp.
